In real-time games, time progresses continuously. This may occur at the same or different rates from the passage of time in the real world. For example, in Terraria, one day-night cycle of 24 hours in the game is equal to 24 minutes in the real world.{{Cite web |last=Meunier |first=Nathan |date=2011-05-25 |title=Terraria Review |url=https://www.ign.com/articles/2011/05/25/terraria-review |access-date=2024-10-30 |website=IGN |language=en}}

In a multiplayer real-time game, players perform actions simultaneously as opposed to in sequential units or turns. In competitive games, players must consider that their opponents are working against them in real time and may act at any moment. This introduces additional challenges.

Many sports, such as soccer or basketball, are almost entirely simultaneous in nature, retaining a limited notion of turns in specific instances, such as the free kick in soccer and the free throw and shot clock in basketball. In the card games Nerts{{cite book |last1=Parlett |first1=David |author-link=David Parlett |title=The Penguin book of card games |date=2008 |publisher=Penguin |isbn=978-0-141-03787-5 |location=London |page=544}} and Ligretto,{{Cite web |title=Ligretto (Playroom blue set edition) {{!}} Board Game Version {{!}} BoardGameGeek |url=https://boardgamegeek.com/boardgameversion/172916/playroom-blue-set-edition |access-date=2023-08-28 |website=boardgamegeek.com |language=en-US}} players must compete to discard their cards as quickly as possible and do not take turns.

In turn-based games, game flow is partitioned into defined parts, called turns, moves, or plays. Each player is allowed a period of analysis (sometimes bounded, sometimes unbounded) before committing to a game action.

Turns may represent periods of time, such as hours, days, or years.{{Cite web |title=Game Theory (Ferguson) |url=https://www.math.ucla.edu/~tom/Game_Theory/mat.pdf |url-status=dead |archive-url=https://web.archive.org/web/20180516185509/http://www.math.ucla.edu/~tom/Game_Theory/mat.pdf |archive-date=May 16, 2018 |access-date=January 8, 2018}}{{Cite web |year=2016 |title=The Path to Equilibrium in Sequential and Simultaneous Games |url=http://www-bcf.usc.edu/~brocas/Research/simseq.pdf |vauthors=Brocas, Carrillo, Sachdeva}} This is common in 4X video games like the Civilization series{{Cite web |last=Axon |first=Samuel |date=2024-08-20 |title=Civilization VII hands-on: This strategy sequel rethinks the long game |url=https://arstechnica.com/gaming/2024/08/civilization-vii-preview-a-new-age-dawns-for-this-decades-old-4x-series/ |access-date=2024-10-31 |website=Ars Technica |language=en-US}} and world-building tabletop role-playing games.

Turn-based games come in two main forms: simultaneous or sequential (also called player-alternated). Diplomacy is an example of a simultaneous turn-based game. There are three types of player-alternated games: ranked, round-robin start, and random. The difference is the order in which players start a turn. In ranked player-alternated games, the first player is the same every time. In round-robin games, the first player selection policy is round-robin. Random player-alternated games randomly select the first player. Some games also decide the order of play using an initiative score based on players' attributes, positions within the game, or dice rolls. Dungeons & Dragons and Wizard101 are examples of this style.{{Cite web |last=Cardosa |first=Rowan |date=2024-03-20 |title=Dungeons & Dragons: 8 Best House Rules For Initiative |url=https://www.thegamer.com/dungeons-dragons-best-homebrew-initiative-rules/ |access-date=2024-10-30 |website=TheGamer |language=en}}{{Cite web |last=Neal |first=Chris |date=2021-03-02 |title=Choose My Adventure: The combat is the sauce in Wizard101 {{!}} Massively Overpowered |url=https://massivelyop.com/2021/03/02/choose-my-adventure-the-combat-is-the-sauce-in-wizard101/ |access-date=2023-09-08 |language=en-US}}

The term turn-based gaming is also used for play-by-mail games and browser-based gaming websites that allow long-term gameplay of board games such as Go and chess.

Various adaptations of the real-time and turn-based systems have been implemented to address common or perceived shortcomings of these systems (though they often introduce new issues that did not exist before).{{cite web | last =Davies | first =Gareth | title =Treatise on Combat to Pink Floyd | publisher =RPG Codex | date =December 10, 2002 | url =http://www.rpgcodex.com/content.php?id=21 | access-date = April 5, 2007}} These include:

Timed turns are designed to prevent one player from using more time to complete turns than another. In chess, for instance, a pair of stop clocks may be used in order to place an upper limit on turn length.

In exchange chess, four players on two teams play on two boards with each team taking one white and one black side. A taken piece can be given to a teammate and placed on their board. A player can abuse this game mechanic by taking an opponent's piece, giving it to a teammate, then waiting unusually long to play a turn on their own board—thereby allowing the teammate to use the advantage for many future moves on their board. To avoid this, players are often limited to ten seconds per move—with their opponent being allowed to remove one of the player's pawns from the board for each additional ten seconds consumed.[https://www.schaakbond.nl/sites/default/files/userfiles/schaakbond/handboek/schaakregels/Reglement%20doorgeefschaak.pdf Reglement Doorgeefschaak ("Passing chess rules")] {{Webarchive|url=https://web.archive.org/web/20171023063950/https://www.schaakbond.nl/sites/default/files/userfiles/schaakbond/handboek/schaakregels/Reglement%20doorgeefschaak.pdf|date=2017-10-23}}, retrieved February 7, 2022.{{cite web |last1=Bodlaender |first1=Hans |author-link1=Hans Bodlaender |last2=Scott |first2=Jay |last3=Junta |first3=Cristobal Joseevich |date=March 18, 2002 |title=Bughouse and Tandem Chess |url=http://www.chessvariants.org/multiplayer.dir/tandem.html |access-date=July 29, 2007 |publisher=The Chess Variant Pages}}

The turn-based strategy game Utopia (1982) featured an early example of timed turns.{{cite web|url=http://uk.gamespy.com/articles/495/495918p1.html |title=GameSpy: Utopia - Page 1 |publisher=Uk.gamespy.com |date=August 3, 2004 |access-date=June 23, 2016}} The early Ultima role-playing video games were strictly turn-based, but starting with Ultima III: Exodus (1983), if the player waited too long to issue a command, the game would issue a "pass" command automatically, thereby allowing enemies to take their turns while the player character did nothing.

Time compression is a feature commonly found in real-time games such as flight simulators. It allows the player to speed up the game time by some (usually adjustable) factor. This permits the player to shorten the subjective duration of long and relatively uneventful periods of gameplay.

Many browser-based MMORPGs allocate a number of turns that can be played within a certain period of time, called a tick. A tick can be any measurement of real time. Players are allocated a certain number of turns per tick, which are refreshed at the beginning of each new tick. Tick-based games differ from other turn-based games in that ticks always occur after the same amount of time has expired.

In some real-time games, game actions are timed according to a common interval that is longer than the duration of play in the real world. For instance, non-player characters might only begin actions at the beginning or end of a round. Some video games such as the Baldur's Gate series use a rounds system based on tabletop role-playing games such as Dungeons & Dragons.

The "Active Time Battle" (ATB) system was introduced by Hiroyuki Ito in Final Fantasy IV (1991).{{cite web | url = http://www.gametrailers.com/player/27455.html | archive-url = https://web.archive.org/web/20090306070051/http://www.gametrailers.com/player/27455.html | archive-date = March 6, 2009 | title = Final Fantasy Retrospective Part XIII | publisher = GameTrailers | date = November 2, 2007 | access-date = March 30, 2009}} ATB combines turn-based combat with a continuous flow of actions and variable wait times.{{US patent reference | number = 5390937 | y = 1995 | m = 02 | d = 21 | inventor = Hironobu Sakaguchi and Hiroyuki Itou | title = Video game apparatus, method and device for controlling same}} Enemies can attack or be attacked at any time.{{cite web|url=http://www.gamespot.com/features/vgs/universal/finalfantasy_hs/sec1_4_2.html|title=The History of Final Fantasy — Final Fantasy IV|date=November 2, 1998|publisher=Gamespot|archive-url=https://web.archive.org/web/20121105062237/http://www.gamespot.com/features/vgs/universal/finalfantasy_hs/sec1_4_2.html|archive-date=November 5, 2012|author=Andrew Vestal|access-date=December 31, 2008}} The ATB system was further developed in Final Fantasy V (1992), which introducing a time gauge showing which character's turn is next.{{cite book|last1=Meyers|first1=Andy|title=Final Fantasy V Advance: The Official Nintendo Player's Guide|date=2006|publisher=Nintendo|isbn=9781598120172|pages=14–15}} The ATB system has since been used in VI (1994), VII (1997), VIII (1999), IX (2000), and X-2 (2003). Both Final Fantasy XII (2006) and XIII (2009) used heavily modified versions of the system. The ATB system was also used in Chrono Trigger (1995).

In simultaneously executed games (also called "phase-based", "We-Go" or "Turn-based WeGo"), turns are separated into two distinct phases: decision and execution. In the decision phase, each player simultaneously plans and determines their units' actions. In the execution phase, all players' chosen actions occur automatically and at the same time. One early example is the 1959 board game Diplomacy. Video game examples include Laser Squad Nemesis (2003), the Combat Mission series, Master of Orion series, Star Hammer: The Vanguard Prophecy (2015) and Battlestar Galactica Deadlock (2017).

Clock-based games tie all unit actions directly to the game clock. Turns begin and end depending on the duration specified for each action, resulting in a sequence of turns that is highly variable and has no set order. It is also possible for different players' actions to occur at the same time with respect to the game clock, as in real-time or simultaneously executed games. Examples of video games that use a clock-based system include Typhoon of Steel (1988) and MechForce (1991), both originally for the Amiga.

In some games, the sequence of turns depends on the initiative statistic of each unit, no matter which side the unit belongs to. Games of this type are still technically sequential, as only one unit can perform an action at a time, and the duration of actions is not tied to the game clock. Examples include the video games The Temple of Elemental Evil (2003) and Final Fantasy Tactics (1997).

Some games allow players to act outside of their normal turn by interrupting an opponent's turn and executing additional actions. The number and type of actions a player may take during an interrupt sequence is limited by the number of points remaining in the player's action point pool carried over from the previous turn. Examples include the X-COM series of video games, the board wargame Advanced Squad Leader (1985), and attacks of opportunity in Dungeons & Dragons. Newer editions of Dungeons & Dragons also allow a Ready-action to prepare an action to be executed during the enemy's turn. This is also implemented in some video games, such as Solasta: Crown of the Magister (2020).

The Silent Storm video game series includes an "Interrupt" statistic for each character, to determine the likelihood of out-of-turn action. In the video game M.A.X. (1996), defensive units may be set to fire out of turn instead of on their own turn. In the board game Tide of Iron, a special card interrupts an opponent's turn to perform an action. In the Mario & Luigi series, the player often has the opportunity to "counterattack" on the enemy's turn, causing damage and often halting the attack.

In some turn-based games, not all turns are alike. The board game Imperium Romanum II (1985), for instance, features a "Taxation and Mobilization" phase in every third turn (month), which does not occur in the other turns. In the video game King Arthur: The Role-Playing Wargame (2009), every fourth turn, the season turns to winter, the only time when buildings can be constructed. In the board game Napoleon (1974), every third player turn is a "night turn" when combat is not allowed.

Other turn-based games feature several phases dedicated to different types of activities within each turn. In the Battle Isle series of video games, players issue movement orders for all units in one phase, and attack orders in a later phase. In the board game Agricola (2007), turns are divided into three phases: "Upkeep", "Replenishing" and "Work." A fourth "Harvest" phase occurs every few turns.

Some games that are generally real-time use turn-based play during specific sequences. For example, the role-playing video games Fallout (1997), Silent Storm (2003){{cite web | last =Butts | first =Steve | title =Silent Storm Review | publisher =IGN | date =January 27, 2004 | url =http://pc.ign.com/articles/475/475977p1.html | archive-url =https://web.archive.org/web/20040202085434/http://pc.ign.com/articles/475/475977p1.html | url-status =dead | archive-date =February 2, 2004 | access-date =December 12, 2007}} and Baldur's Gate 3 (2023) are turn-based during the combat phase and real-time throughout the remainder of the game.

In real-time games with an active pause system (also called "pausable real-time" or "real-time with pause"), players can pause the game and issue orders. When the game is un-paused, the orders automatically execute. This offers additional tactical options, such as letting players issue orders to multiple units at the same time.{{cite book |last1=Barton |first1=Matt |url=https://books.google.com/books?id=IMXu61GbTqMC |title=Dungeons And Desktops: The History Of Computer Role-playing Games |date=2008 |publisher=A K Peters |isbn=978-1568814117 |location=Wellesley, Massachusetts |access-date=September 8, 2010}}

In Baldur's Gate, players may also let the artificial intelligence take control during combat and press the spacebar at any time to regain control of their characters. Further, in Baldur's Gate, players are able to configure the game to automatically pause when certain conditions are met, such as at the end of a round or upon the death of a non-player character. A variation of active pause, called "Smart Pause Mode" or SPM, is a feature of Apeiron's Brigade E5: New Jagged Union (2006) and 7.62: High Calibre (2007).{{cite web | last = Tait | first = John | title = Brigade E5: New Jagged Union — PC Game Reviews — The Armchair Empire | publisher = The Armchair Empire | date = January 30, 2007 | url = http://www.armchairempire.com/Reviews/PC%20Games/brigade-e5-new-jagged-union.htm | access-date = November 13, 2008}}{{cite web | title = Strategy — Brigade E5: New Jagged Union | publisher = Strategy First | url = http://www.strategyfirst.com/en/games/BrigadeE5/ | archive-url = https://web.archive.org/web/20101007054733/http://www.strategyfirst.com/en/games/BrigadeE5/ | archive-date=October 7, 2010 | access-date = June 18, 2008}}

The grand strategy games developed by Paradox Interactive exclusively use pausable real-time. It was the originally intended mode of the Civilization series before the developers decided to switch to turn-based. It has been present in the SimCity construction and management simulation series since SimCity (1989) and is also used in the Transport Tycoon and RollerCoaster Tycoon series.

In the single-character console RPGs Parasite Eve (1998) and Vagrant Story (2000), the player can pause the game to take aim with a weapon.{{cite web|title=Retronauts: Volume 4 - Yasumi Matsuno|author=Jeremy Parish|publisher=1UP.com|date=March 18, 2006|url=http://www.1up.com/features/retronauts-yasumi-matsuno|access-date=April 9, 2011|url-status=dead|archive-url=https://web.archive.org/web/20130223182908/http://www.1up.com/features/retronauts-yasumi-matsuno|archive-date=February 23, 2013}} In Vagrant Story, this allows players to target specific body parts while the game is paused.

Some games use a timeline as part of a game mechanic that lets players establish or alter the order of events within the game world.

A progress clock is a tabletop role-playing gamemaster (GM) tool for keeping track of ongoing events that cannot be handled within a single turn, such as the player characters' continuous headway toward defeating a challenge, the gradual approach of an enemy, or a time-limited window of opportunity. The GM draws a segmented circle to represent a clock face, then fills in a segment whenever progress develops toward the outcome. Progress clocks are important in the heist film-inspired game Blades in the Dark and other games that adapt its Forged in the Dark system.{{Cite web |title=Progress Clocks {{!}} Blades in the Dark RPG |url=https://bladesinthedark.com/progress-clocks |access-date=2024-10-31 |website=bladesinthedark.com}}{{Cite web |last=Sklar |first=Patrick |date=2021-01-09 |title=Play Blades In The Dark If You Want Your Heists To Feel Cinematic |url=https://www.thegamer.com/blades-in-the-dark-tabletop-rpg-why-play/ |access-date=2024-10-31 |website=TheGamer |language=en}}

Debates occur between fans of real-time and turn-based video games based on the merits and flaws of each timekeeping style.{{cite news | last =Saltzman | first =Marc | title ='Nations' offers 2 types of game play | publisher =CNN.com | date =July 1, 2003 | url =http://www.cnn.com/2003/TECH/fun.games/06/26/rise.nations/index.html | access-date =December 2, 2007}}{{cite web | last =Breeden | first =John | title =A Thinking Man's Wargame | publisher =Game Industry News | url =http://www.gameindustry.com/review/item.asp?id=877 | access-date =December 2, 2007 | url-status =dead | archive-url =https://web.archive.org/web/20071217141502/http://www.gameindustry.com/review/item.asp?id=877 | archive-date =December 17, 2007}}{{cite web | title =A Hex on You | publisher =StrategyPlanet | date =December 4, 2000 | url =http://www.strategyplanet.com/features/gaming_is_life/ahexonyou/ | access-date =December 2, 2007 | url-status =dead | archive-url =https://web.archive.org/web/20071231190124/http://www.strategyplanet.com/features/gaming_is_life/ahexonyou/ | archive-date =December 31, 2007}}{{cite web | last =Quick | first =Dan | title =Zeus: Master of Olympus | publisher =GameSpy | url =http://archive.gamespy.com/legacy/interviews/zeus2_a.shtm | archive-url =https://web.archive.org/web/20120910075510/http://archive.gamespy.com/legacy/interviews/zeus2_a.shtm | archive-date =September 10, 2012 | access-date =December 2, 2007 | url-status =dead}}{{cite web | last =Maddox | first =John | title =Interview: John Tiller on Game Design and His Perceptions of the Industry | publisher =Gamesquad.com | date =April 26, 2001 | url =http://www.gamesquad.com/index.php?option=com_sections&id=6&sid=207 | access-date =December 2, 2007}}

Arguments made in favor of turn-based systems include:

• The extra time available to players in turn-based systems allows them to plan their moves to a greater degree,{{cite web | title =Point — CounterPoint: Turn Based vs. Real Time Strategy | publisher =StrategyPlanet | date =June 27, 2001 | url =http://www.strategyplanet.com/features/articles/pcp-turnvsreal/ | access-date =April 5, 2007 | url-status =dead | archive-url =https://web.archive.org/web/20070226185919/http://www.strategyplanet.com/features/articles/pcp-turnvsreal/ | archive-date =February 26, 2007}}{{cite web | title =Icarus: Sanctuary of the Gods Review | publisher =Yahoo!

• Games are fairer due to a lack of reliance upon player reflexes. A player with slower reflexes is not at a disadvantage compared to faster players; rather, only the ability to think through and solve the current problem is important.
• Games can have better artificial intelligence due to the greater amount of computer processing power available to them.
• It is more realistic to control multiple units intelligently using this system, as players do not have to divide their attention among multiple independent units all moving simultaneously. Likewise, it is easier to keep track of what the enemy is doing at all times since the player is typically informed of every move in advance (not taking into account fog of war).

Arguments made in favor of real-time systems include:

• Armies pausing mid-combat to take turns and act in a sequential manner is unrealistic. Real-life combat occurs simultaneously with no side pausing to let the other side move.
• Thinking and acting quickly are part of the strategy, providing additional challenge.
• Real-time systems are viscerally exciting and add to players' sense of immersion. Players feel more like they are experiencing game events first-hand.
• Turn-based games have too many rules and are difficult to master.
• Real-time games are more multiplayer-friendly, since sitting around and waiting while other players take their turns can become tiresome.
• The added element of a shared clock prevents gameplay from becoming an easily repeatable series of steps. The reliance upon player timing makes outcomes highly variable.
