Fairtris is a video game, a clone of the 32-year-old Tetris® game produced by Nintendo for the Famicom and NES consoles, designed for modern Windows systems. Fairtris is not an emulator — it is a full-fledged game with OpenGL support via the SDL library (using the SDL2-for-Pascal headers). Thanks to this combination, it is super-fast and ultra-light. This project was initially created as a tool to test various RNG algorithms, but after some time it turned into a complete and rich video game and a knowledge base for those who would like to know more about the internal mechanisms of the classic version of this game. For more information, see the project wiki on GitHub.

Important features:

  • implementation of gameplay mechanics compatible with the Nintendo Tetris® game,
  • DAS mechanics fixed and spin buffering added, making the controls fabulously responsive,
  • extended mechanics with basic wall kick, hard-drop and multi-spawn soft-drop,
  • support for eight regional versions of the game, including original NTSC and PAL versions,
  • support for as many as seven random piece generators, including the classic RNG,
  • support for free marathon and speedrun modes, qualifications and matches with same piece set,
  • the ability to start the game from any level up to the killscreen,
  • the ability to play on a keyboard or any USB controller (with input mapping support),
  • supports window mode and exclusive video mode,
  • support for additional meters, such as TRT, BRN, as well as gain popup,
  • stores the best results for each game region and RNG type,
  • has a pause menu with the ability to quickly restart the game and change settings,
  • shows the game summary screen after each game,
  • support for two themes (minimalistic dark and classic skin),
  • possibility to use it with NestrisChamps and MaxoutClub,
  • it's light and very fast — should run smoothly even on a heavily loaded PC,
  • it is fully portable, no installation required,
  • and many more!
