Tetris for Sega Mega Drive/Genesis, an adaption of 1988 arcade game, went unreleased due to various licensing issues.

Game Modes

• Normal: The game continues until the player dies
• Time Trial: A three minute countdown
• Doubles: Two-player co-op

Gameplay Details

• ARE without a line clear: 41 frames
• Line clear delay: 17 frames
• ARE after a line clear: 24 frames
• Lock delay is either 12 or 19 frames, selected seemingly random
• DAS: 6 frames initial, 6 frames auto repeat
• Hard Drop is 1G and disables all controls of the piece until it locks. There is no special bonus for this move. Both soft and hard drops of T, J or L pieces at the beginning of level 0 give the player 38 points.
• Level increases for every 10 lines as opposed to 4 lines in the original. There seems no level timer mechanics.
• Doubles mode has 2x2 invisible wall at the top-center of the playfield, presumably to prevent a player's active piece to overlap with the other player's newly spawned pieces.

Scoring

Scoring in this game is very different from the arcade original, encouraging players to place the pieces on high places.

Score = 2 + (Level*3) + (((Lowest row-1) + Manual drop rows)*2) + (Line clear bonus)

• The first 2 points is awarded no matter what. This is the minimum points the player receives when the player let a piece fall to the bottom of the playfield in level 0 without doing anything.
• (Level*3) is also awarded for every piece except in level 0. This is the only bonus where the level number matters.
• (Lowest row-1) is the minimum Y position the piece landed. The minimum is 0 when the piece is directly placed on the floor. The maximum is 19 when the player places a horizontal I Tetromino on the 20th row.
• Manual drop rows is the number of rows passed with a soft or a hard drop. Note that this is awarded only when the player manually cancels a lock delay. Letting a piece lock by itself will set this bonus to 0.
• Line clear bonus follows the following table. Note that it doesn't increase with levels.

Line clear bonus

Lines cleared	Points
1 (single)	20
2 (double)	50
3 (triple)	120
4 (tetris)	300

Items

This game has an items option. When enabled, a flashing Tetromino will appear for every 10 pieces. When at least one line is cleared with the flashing Tetromino, the item will activate its effect. Excluding the S Tetromino, when these flashing Tetrominos are placed without clearing lines, they will stop flashing and thus the item is lost. The item effects are specific to each Tetromino:

• I: Activates a random effect from other Tetrominos.
• O: Gives you larger line clear bonus.
• Z: Gives you slightly larger line clear bonus.
• T: Erase nearby three lines.
• J: Increases the level by one.
• L: Reduce the level by one.
• S: This item does not disappear when placed, and do different things depending on whether the S Tetromino was "activated" by immediately clearing lines like other items, or when "placed" on the field without clearing lines.
  • Placed: It will continue flashing in the field and will disappear after 10 seconds. There seems no special effects when "placed" S blocks are cleared before disappearing.
  • Activated: The whole S Tetromino disappears when the lines are cleared, in addition to the blocks included in the lines.
