Tetris

In Tetris game, players should manipulate Tetrominos, which are variants of tile set, to make as many tiles-filled rows as possible. Whenever a tiles-filled row is formed, all tiles in that row will disappear and the player win 10 points. Besides, additional lines clear at once or combos will give players 10 points of bonus for each. On the other hand, when any Tetromino surpasses the skyline or 1-minute-time is up, the game will end.
