Linesweeper

Somewhere there is a garden. In that garden are bushes, and in some of those bushes sit cats — smug, motionless, entirely invisible cats.

You are not allowed to touch a bush. Digging is Checkers' work. They are parked all around the garden, one per row and one per column, each wearing a number on its face like it is doing you an enormous favour. That number is every piece of truth you are going to get today.
