Tetris S (テトリスS) is a puzzle game developed by Bullet-Proof Software for the Sega Saturn. It is a variation of Tetris made specifically for the Sega Saturn system (unlike Tetris Plus, which was an arcade port). During development it was known as BPS Puzzle, possibly until the Tetris license could be secured.


The game is a version of Tetris that is very similar to Sega's 1988 arcade version of Tetris, using the Sega rotation scheme, a similar presentation, and an identical ruleset, albeit with enhanced graphics and sound. It contains only a one-player endless mode and a two-player competitive mode (against either a human or a computer opponent). It features a purple ape as a mascot (recalling the monkey that appears in the Sega arcade game), who appears during gameplay to encourage the players and to throw bananas to speed up a player's blocks in the competitive mode.

Like other Tetris games, pieces called tetronimoes fall into the playfield one at a time in a random order, and the player must fit them together in such a way as to form complete lines, which are then cleared. Eliminating multiple lines at a time awards more points. The next piece is visible at the top of the playfield before it drops. The game ends if the playfield fills so that the player can no longer place new pieces.

Pieces are moved with Left and Right. They are dropped faster with Down (which awards extra points). Pieces are rotated clockwise with B or counterclockwise with A or C.

Classic Mode

This is a single-player endless mode that continues until the player loses. The game starts at level 0, and the level increases (up to level 99) for every four lines eliminated or otherwise when forty seconds passes. The speed of the game increases and the background changes at certain levels. The game lasts until the player loses; the player is given the option to continue the game at the previous level, with an empty playfield.

Vs Mode

There are two versus modes, Com Vs for one player to compete against a computer player and 人 Vs for two players to compete against each other. The goal is to outlast the other player. Matches are played to the best of 3 games (which can be changed to any number between 1 and 5 in the options). There are five difficulty levels for computer opponents (Easiest, Easy, Normal, Hard, and Hardest).

When a player clears multiple lines at once, instead of sending additional lines to the opponent (as is common in other Tetris games), the ape throws a banana at the opponent that increases the speed at which a certain number of the opponent's pieces drop. Eliminating more lines at once increases the number of pieces that are sped up. A double (two lines at once) speeds up 1 piece, a triple (three lines at once) speeds up 3 pieces, and a tetris (four lines at once) speeds up 5 pieces.
