Check sheet is also available to find which number is filled in already on the screen.

2 types of check marks here:

When you tap once, a check-mark is displayed in green.

When you tap again, it turns to a cross-mark, and the number would turn into gray accordingly.

It'd be recommended making your own rules in advance. For example, count a check-mark as the number you are looking for, and a cross-mark as the number you already filled in. This way you can continue the game very smoothly after the break.
