Your task is to quickly mark the even numbers that appear on the cards that continuously move from top to bottom, each card has a size that covers the entire screen and contains a number with an even or odd value; before the even number disappears, you need to touch it to mark it, if the even number has been marked before disappearing, you will score points, otherwise, you will lose if you let the even number disappear without being marked or if you touch the odd number.
