Tetra Blocks

This is a classic puzzle-game app similar to Tetris. A tetra block is a figure consists of four squares. Tetra blocks drop and stack in a space consists of 10x20 cells continuously. You can horizontally move, or rotate a tetra block counter-clockwise or clockwise before it drops down the bottom. Once you piece together the stacked blocks in rows, they are removed. You get more scores if you remove more rows with single tetra block.

The game has 10 levels, and the dropping rate of tetra blocks increases with the levels. When the blocks stack and reach to top of the space, the game ends. In addition to the classic play, the app adds holding, bomb tetras, and the struggling time to the games. This provides you more tactics and fun when playing the game.
