In this game, you'll tap numbers or letters on a grid in increasing order, like 1 to 2 to 3 or A to B to C, as fast as you can. First, pick how big you want the grid to be and whether you want to use numbers or letters. Once you're ready, start the timer and begin tapping the tiles in the right sequence. When you tap correctly, the tile turns green and locks in place, but if you make a mistake, the tile will flash red. The clock stops once you've tapped all the tiles in order, showing you how long it took. Try to beat your previous times to improve your focus, visual perception, and quick thinking skills. Playing every day can help you get faster and more concentrated. Have fun with the challenge!
