The game starts with an 8 by 10 cell field (the background can vary, but the field is a standard rectangular matrix) and blocks ranging from 1 to 4 cells in length. At the beginning, these blocks create an initial row with randomly placed empty spaces. Players can swipe left or right to move any block into an empty space. After a move, all blocks on the field shift up one cell, and a new row of blocks appears at the bottom. Players can only move blocks if there is free space available. During gameplay, moving a block may create a void underneath it or another block, causing that block to drop down. The objective is to form complete rows of blocks without any gaps. When a row is successfully formed, it disappears, and the blocks above it fall down. Players earn points for each completed row. The game ends when the blocks reach the top of the matrix.
