Flip's Number Hunt

For grown-ups
- Children check sums and products in their head, over and over, to rule numbers in or out. That is the fact practice, hidden inside a puzzle.
- Every group has exactly one answer, and a wrong tap only says “try another.”
- The timer is off unless you turn it on. Best times stay on this device. Nothing to sign up for.
