Tetris Battle Gaiden is a Tetris game developed and published in 1993 by Bullet Proof Software for the Super Famicom. Rather than playing solo, the only game type in Tetris Battle Gaiden is versus matches, vs a CPU opponent, or a local opponent. The game is notable for its unique gameplay involving crystals and character abilities.

Gameplay

Both players draw from the same 3 piece preview. The player who places the next piece gets the next one at the top.

Some tetrominos have crystals in them. Players must clear a line containing a crystal to collect it. This brings a lot of strategy for the timing of your piece drops because you want to get the ones with crystals, and leave the ones without crystals for the opponent. However you also want to let the opponent have the pieces you don't have a spot for, and get the ones you do want.

• 1 crystal is usually a small attack or a defensive move,
• 2 crystal usually interferes with the opponent's screen or controls,
• 3 crystal is something unique for each character, e.g., Halloween's 3 crystal move is to steal the opponent's crystals,
• 4 crystal is a powerful attack.

Topping out

Blocks that get pushed up the vanishing zone are deleted. The only way to top out is by place a tetromino partially or fully above the 20th row.

Characters and abilities

	Halloween
	Level 1 Fry - Fills the bottom 3 rows with blocks. These lines are cleared once the next piece is placed, and the lines are sent to the opponent. Crystal blocks are converted into normal blocks and are not collected. Level 2 Dark - Blacks out the opponents playfield, and only a small section under the active piece is visible. Level 3 Vampire - Steals the opponent's crystals. Level 4 Bomb - Destroy random blocks on the opponent's field.
	Mirurun
	Level 1 Mirurun - Removes the bottom four rows of the player's field. The lines removed are not sent to the opponent. Level 2 attack - Level 3 Pentris - Send five lines of garbage to the opponent. Level 4 Sirtet - All rows containing blocks on the opponent's field are inverted, so that spaces are converted to blocks and non-crystal blocks are converted to spaces.
	Shaman
	Level 1 Moses - The playfield is split in two, blocks on the left of the center are pushed two columns to the left, and blocks to the right are pushed two columns to the right. Blocks at the extremities are pushed out and lost. Any floating non crystal blocks fall as far as they can. This leaves a 4 wide center well. Blocks do not fall after the split if they are stone, or if Ninja's web attack is active. Level 2 Rotation - The opponents next 3 pieces will rotate rapidly when they try to soft-drop. Rotating a piece with A or B buttons will rotate the piece rapidly as well. If a piece cannot rotate, such as when next to a wall, it can not be soft dropped. Pieces can also not be manually locked. Level 3 Curse - Level 4 attack -
