Hint

Reveal a hint

A spider is hiding under the rock, and the tiny ones on the buttons still count.

Why It Works

Counting works only if you find every spider, not just the obvious ones. Dragging the rock reveals the hidden spider, and adding the spiders on the numbers, cross, and checkmark gives 20, which you type in and confirm.
