It's a mix between Connect 4 and Tetris. Use AD, arrow keys, or mobile controls to move the block around. The block moves downward as well, and you can either wait until your block touches the ground or another block, or you could press space to drop your block. If one row is completely full, then it will disappear, like in Tetris.
