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. The game is played using giant versions of ball top joysticks called Dekacons, on a cabinet with a 70" projector screen.

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.

Arcade operators can choose to allow the selection of Kids Mode, which limits the available tetrominoes to JLOIT.

Score Attack Mode

The goal of Score Attack Mode 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 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 Attack Mode

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. Bonus time is given when line clears are made. Topping out does not end the game, instead the field is cleared and a time penalty is given.

Bonus time

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

2P Score Attack Mode & 2P Line Attack Mode

In 2P 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 exchange each other's pieces up to three times.

2P Battle 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.

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.
