The game contains a field of 8 by 10 cells (the background can be any, the main thing is that it is a classic rectangular matrix) and blocks of length from 1 to 4 cells. At the beginning of the game, these blocks form a starting row with randomly placed empty spaces. The user can swipe (left or right) to move any block to an empty space. After moving, the blocks on the field go up one cell and a new line with blocks appears at the bottom.

A player can move any block if there is a free space. During the game there may be situations when a void forms under a block or another block, which causes it to fall down. The goal of the game is to collect rows of blocks without gaps. The player needs to move the blocks to form solid rows. When a row is collected, it disappears and the blocks above it fall down. The player gets points for the collected row. The game ends when the blocks reach the upper border of the matrix.
