EA Tetris is a licensed Tetris game for Apple iOS, available for 0.99 USD. There is a membership option, which gives lower shop prices, earns 15% more in-game coins, and a 15% higher score for line clears. The membership, called the T-Club, costs 2.99 USD for one month or 29.99 for twelve months.
 One-TouchOne touch mode offers a simpler way to control the tetriminos, by tapping the screen instead of dragging and sliding them. 1-5 possible placements will show up, and by tapping the outline, the tetrimino will drop there.
Marathon is like normal Tetris, but the controls are different since you are playing on a touch screen. You slide your finger left or right to move the Tetrimino left or right, swipe down to perform a hard drop, slide down to perform a soft drop, and tap the "Hold" icon to hold a piece. T-spins, Tetrises, Combos, and Back-to-back Tetrises can be performed in this mode.
Galaxy is an exclusive feature to the iOS edition. It is similar to one-touch, but the playing feild is smaller, tetriminos are not randomly generated, and there are some blocks already onscreen. Players place tetriminos to remove the onscreen blocks. As you progress through Galaxy, Power-ups such as the fragment and the anvil appear. The better you do in Galaxy, the more T-Coins you earn, which can be used to buy songs or extra levels in Galaxy.
