Tetris for WonderSwan Color is the first Tetris Guideline compatible game in Japan. (8 days earlier than GBA version of Tetris Worlds)

Modes

• Marathon: Endless mode. Uses a variable goal system, with the number of lines required to advance a level being level*5 (no carry-over between levels). The maximum level is 15.
• 40 Lines: Clear 40 lines as fast as possible. However, this is not really 40 lines mode. See details about "Lines" in Scoring section below.
• 3 min: Score as many points as possible in 3 minutes.
• VS: Fight against a human opponent.

The starting level in single player game modes can be adjusted from 1-15.

Options

The following game rules can be adjusted from their Guideline defaults in the Options menu:

• Next Piece: 0-3 (default: 3)
• Ghost Piece: On/Off (default: On)
• Hold: On/Off (default: On)

Scoring

• Line clear score: See Scoring#Original Nintendo scoring system. It is same as Nintendo's scoring system. Base score value is multiplied by current level.
• "LINE" awarded by line clear (This applies to all modes, including 40lines mode)

Single	Double	Triple	Tetris	Back-to-back Tetris
1	3	5	8	12

• Back-to-back Tetris has a bonus for total lines, but no bonus for the score.
• T-Spins have no bonus.
• A Perfect Clear has a big bonus of 1,000,000 points. This bonus is not multiplied by the current level, and is awarded equally for all types of line clears (i.e., a flat bonus without adding the points that otherwise would have been awarded for a normal line clear score).
• Maximum score is 999,999,999 points, while the line cap is 9999.

Timings

• DAS: 12 frames start-up, 4 frames period (= 1/4G)
• ARE: 0 frames
• Line clear delay: 38 frames (0.5 seconds)
• Soft drop: Varies by level.

The following table shows gravity and soft drop speeds for levels 1 to 15.

Level	Frames/row	Soft drop (G)
1	75	1/3
2	59	1/3
3	41	1/3
4	35	1/2
5	20	1/2
6	15	1/2
7	10	1/2
8	5	1/2
9	3	1/2
10	2	1
11	1	1
12	1	1
13	1	1
14	1	1
15	1	1

This game features "diagonal drop," and allows DAS to be preserved between pieces so long as the direction remains held when hard dropping.

Additionally, the design of the WonderSwan features separated directional keys (as opposed to a directional pad) and allows simultaneous opposite directions to be pressed. Pressing left+right cancels out to a "neutral" movement direction, however DAS remains charged when doing so.

Randomizer

This game uses a 7+1 Bag randomizer. It behaves similarly to the 7 Bag randomizer used in other games following the Tetris Guideline, but with a duplicate of one randomly selected piece shuffled in (resulting in a bag size of 8).
