無盡奔跑遊戲

Endless runner (also infinite runner or auto run) is a subgenre of platform game in which the player character potentially runs for an infinite amount of time while avoiding obstacles. The player's objective is to reach a high score by surviving for as long as possible. The method by which the game level or environment appears to continuously spawn before the player is an example of procedural generation. The genre exploded on mobile platforms following the success of Temple Run, Canabalt, and Doodle Jump. Its popularity is attributed to its simple gameplay that works well on touchscreen devices.

Endless runners can be side-scrolling, as in the genre's early titles, top-down, or 3D, but the player is placed in a neverending level in which the character automatically moves forward. The player's only form of control is to have the character dodge obstacles, either by moving out of the way or using a specific button. Some form of points, currency, or other rewards are gained over time by maneuvering in the level or simply staying alive longer. The game progressively increases in difficulty as time goes on. Usually, the player has a game over if they are hindered enough by the obstacles that they are "caught" by whatever is chasing them and die; however, this is not always the case.

The genre has its origins in the vertically scrolling video games of the 1970s, primarily racing games. The player always moves forward, avoiding obstacles and other vehicles. Taito's Speed Race, released in 1974, was the first. In the late 1970s and early 1980s, the same concept was used in skiing games.

Vehicle-oriented platform games, like Jump Bug (1981) and Moon Patrol (1982), added both jumping and shooting as ways to deal with obstacles in continually scrolling levels. River Raid (1982) has no end; the aircraft flies upward on a procedurally generated setting. The home game B.C.'s Quest for Tires (1983) uses the forced-scrolling and jumping gameplay of Moon Patrol.

The idea of being chased relentlessly by an indestructible obstacle, monster, or boss to enforce forward progression was greatly influenced by the boulder scene from the 1981 film Raiders of the Lost Ark. This theme appeared in games like Draconian (1984) in which the player must avoid obstacles while being pursued by an invincible giant dragon. This would become a recurring theme of endless running gameplay.

177 (1986), a controversial adult game for the PC-88, has endless running from a 2D side-scrolling perspective. The 3-D Battles of WorldRunner (1987), a Squaresoft rail shooter for the Nintendo Entertainment System, has endless running from a pseudo-3D third‑person perspective. Atomic Runner Chelnov (1988), an arcade run-and-gun shooter, has several hallmarks of a modern runner with forced scrolling and long jumping onto platforms to avoid hazards. The 1990 Amiga and TV show game Hugo has sequences of pseudo-3D endless running. In Genji Tsuushin Agedama (1991), the player is constantly running in a forced scrolling environment.

Battletoads (1991) has several forced scrolling areas where the player is required to avoid hazards and obstacles. SkiFree (1991) by Chris Pirih and released in Microsoft Entertainment Pack 3 was inspired by the 1980 Atari 2600 cartridge Skiing. The player skis down an endless slope with procedurally generated obstacles, pursued by large indestructible yetis. Score is based on distance traveled. The pinball machine Doctor Who (1992) includes a video mode with forced running and avoiding obstacles.

The emergence of the touchscreen on smart phones and tablets paved the way for the type of simplistic game controls which gave birth to the modern genre.

Doodle Jump (April 2009), a vertical scroller, was one of the first mobile titles to be endless, with game only ending when falling to the bottom of the screen or hitting an obstacle. It was to pave the way for even more popular titles.

The prototypical endless runner, building on Doodle Jump's success, was Canabalt (a common misconception is that Canabalt was the first modern endless runner, but Ovenbreak was added to the App Store in June 2009, two months prior to the release of Canabalt in August 2009), an indie game developed by Adam Saltsman in which the player flees from a city being destroyed by giant robots that is procedurally generated and infinite. Cannabalt used distance gained as the main scoring system. These were both common elements of subsequent runners. The 2D scroller limited movement to leaping and dodging obstacles simply by touching the screen, overcoming control limitation of touchscreen devices. Adult Swim Games soon asked Saltsman for permission to adapt Canabalt's design into their own title, and released Robot Unicorn Attack (2010). It became an internet meme due to Adult Swim's larger audience and its quirky themes.

Endless runners became known for the addictiveness of their gameplay. This also led to them being monetized using the Free to Play model. Monetization tactics used in endless runners included virtual
