Victory Vault: Grid Clash

The game initially presents a field of 8 by 10 cells (the background can be any, the main thing is that the field is a classic rectangular matrix) and blocks of length from 1 to 4 cells. When the game starts, these blocks form the initial row with empty spaces in random positions. The user can swipe (left or right) to move any block to an empty space. After that, the blocks on the field are moved up one cell, and a new line with blocks appears at the bottom of the matrix. A player can move any block if there is a free space to move. During the game there may be situations when when moving a block, a void is formed under it or under another block, and this block falls down. The goal of the game is to collect rows of blocks without voids. The player must move the blocks in such a way 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.
