VS ブロックVS BLOCK is a free puzzle game developed by kngw for Android devices. This game is a computer-based falling block game where the opponent's blocks increase as the player clears lines. The game has two modes, "Normal Mode" where the player competes against the computer, and "Time Trial" where the player competes against the computer to clear lines in the shortest amount of time possible.

The game is controlled by sliding the blocks left, right, and down, flicking them downwards to move quickly, and tapping to rotate them clockwise. When the player clears a line, the blocks in that line disappear, and the player's score is determined by the number of lines cleared, the speed of the blocks, and the height of the lines. As the player clears more lines, their level increases, and the speed of the blocks changes. If the player reaches a score of zero, they lose the game, and the opponent's score increases. When the computer loses the game, a 10,000-point bonus is added in Normal Mode, and the strength of the computer changes. In Time Trial mode, a bonus is awarded based on the time taken to win, but if it takes more than 1000 seconds, there will be no bonus.
