Tap numbers or letters on the grid in ascending order (1→2→3… or A→B→C…) as quickly as possible. Choose a grid size and mode (numbers or letters). Start the timer, then tap tiles sequentially. Correct taps turn green and lock; wrong taps flash red. The timer stops when the last tile is tapped, displaying your completion time. Challenge yourself to beat your best record! This game trains focus, visual perception, and cognitive agility, making it perfect for brain training. Practice daily to improve speed and concentration. Enjoy the challenge!
