GridQuickFill is an endless fill game with a blank grid marking empty cells at random. Tap each empty cell quickly to fill it for ten points. Failing to clear them before the timer ends is a fault, and three faults end the run. Grids grow larger, empties refresh faster, and fill windows shrink as your score rises. Rules stay clear with no stages to unlock. After the lights fade, review your score and high score, return to the main screen, and chase a longer clean fill streak under rising pressure.
Tap empty grid cells before time runs out. Timeouts are faults.
