With a name so ingrained into computer game history, there are not many gamers who haven't played Tetris. Created by Soviet engineer Alexey Pajitnov in 1984, Tetris is perceived as probably gaming's greatest hit, and has established itself as one of the most outstanding selling computer game franchises of all time.
The enduring popularity of Tetris, as well as its status as a retro game with a straightforward, easy-to-understand gameplay circle, has made it into the ideal avenue for players to showcase their talents by recreating Tetris in other games like Minecraft or - in this case - for programmers to foster an AI that plays through the game with increasingly better proficiency. Generally, this effectiveness far surpasses that of a normal human player - allowing players, programmers, and other interested parties something else entirely into their favorite games of old.
In this particular example, programmer Greg Cannon shared a gameplay video of his StackRabbit AI playing through the NES form of Tetris in which the AI managed to advance so far as to break the game completely. While as yet being dependent upon the arbitrary savagery of Tetris handing players an adequately large succession of alternating S and Z tetrominoes, the AI was not limited as far as reaction times or input procedures the way a human would normally be.
The conventional ending for this particular form of Tetris was intended to be Level 29, where the speed of the game would make finding solutions on the fly out and out unthinkable. Notwithstanding, thanks to StackRabbit AI, Greg Cannon was able to easily advance into more significant levels that weren't intended or accounted for by the game's programming.
After getting past the 29th level, Tetris started to exhibit strange behaviors, for example, generating messed with shading plans, or breaking the game's level indicator and score tally altogether. The shading plans for the levels were lovingly given amusing nicknames, for example, "Stardew Valley Sunset", "Week-old Bubblegum" or "Internship at Marie Curie's Lab" - and there was even an instance of an "unending" (Level 235) addressed with a monotone dark green shading plan that continued to go almost ceaselessly from a score of 59 million to 101 million points.
The game eventually gave up, gave up, and broke completely at Level 237, with 102 million points as the final score. An interesting statistical takeaway is that significantly north of 8,000 tetrominoes later, the exceptionally pined for I shaped ones were as yet the rarest type by a noticeable margin. Some individuals have inactively contemplated whether Tetris at any point had an ending, and a resounding answer to that age-old inquiry has at last been given.
