At the beginning pick a number from 10 to 25. After you have picked a number, a bunch of squares with one-digit numbers on them will appear. And you need to click on those digits and have them add up to the sum. Like, if you chose the number 10 in the beginning, then if you see a 1, an 8, and another 1 on the screen, click on those numbers and you will get points! But remember, if you chose a big number, it might be hard to count up what numbers you already have clicked on. That's why there's a counter, which counts for you!
