Tetris Giant (known as テトリス デカリス Tetris Dekaris in Japan) is a Tetris arcade game developed and published by Sega. It was released for arcade on the Sega System SP platform in Japan in December 2009, and in the west in 2010. The word Dekatris comes from the Japanese word Dekai, meaning huge, and ris from the word Tetris. The game is played using giant versions of ball top joysticks called Dekacons, on a cabinet with a 70" projector screen. In 2-player mode, players can choose between cooperative or competitive modes.

The soundtrack was performed by Team Dekaris and produced by Hiroshi Kawaguchi.

Gameplay

Everything is giant in Tetris Giant, including the blocks. The playfield is 6 × 7 instead of the normal 10 × 20. The game lacks hard drop, and there is no way to manually lock pieces, or hold pieces, so managing a good stack and odd pieces is very important. While locking a tetromino fully above the 7th row will cause a top out, pieces appear in the 9th and 10th row, giving extra room to maneuver over the playfield, and allowing pieces to be set partly over the 7th row.

Arcade operators can choose to allow the selection of Kids mode, which limits the available tetrominoes to JLOIT. In Kids mode single player, only Line Challenge is available.

Score Challenge

The goal of Score Challenge is to score as many points as possible within the 200-line limit, or before topping out. On the left, the Ranking Tower displays the rank in real time, compared to 1000 other scores on the machine.

Scoring

Action	Points
Single	10 × level
Double	30 × level
Triple	50 × level
Tetris	500 × level
T-Spin	40 × level
T-Spin Single	90 × level
T-Spin Double	150 × level
T-Spin Triple	210 × level
Soft Drop	2 ÷ cell

Levels increase every 10 lines, and caps at level 15.

Line Challenge

In this mode, the goal is to clear as many lines as possible before the time runs out or the 200-line limit is reached. By default the time limit is 120 seconds, but the operator can change it to 150 seconds. Bonus time is given when line clears are made. Topping out does not end the game, instead the bottom 7 rows are cleared and wastes about 3 seconds of time.

Bonus time

Action	Time
Single	0 s
Double	+2 s
Triple	+5 s
Tetris	+20 s

Co-op Score Challenge & Co-op Line Challenge

In Co-op mode, two players play cooperatively in a 12 × 7 playfield. The middle two rows are shared, and a player can not move their active piece past that area. You can swap each other's pieces up to three times by pressing the start button.

Versus Mode

If the player clears more than one line at a time, the opponent's piece will speed up and drop faster, it's also possible for the Dekacon to vibrate when this happens. The first person to win two rounds is the winner. Players share the same piece preview.

Development

Tetris Dekaris was announced by Sega on September 11, 2009, and was first playable at the 47th Amusement Machine Show on September 17, 2009. In 2011, A 47” LCD version of the cabinet was also developed, but was only produced in limited quantities.

Reception

During the 47th Amusement Machine Show, Amusement Journal asked attendees to fill out a questionnaire of their favorite games. Tetris Dekaris ranked second most popular arcade game on the first two days, and most popular on the last day. As of April 28, 2010, the official website listed 424 locations with a cabinet in operation in Japan.
