Description
How it works
Players prepare nine index cards each — three showing 2, three showing 5, three showing 10. Both draw a card from the deck without revealing it, then choose which index card to pair it with, aiming for the greater product. Both reveal at once; the greater product scores a point, ties score for both. First to five points wins. The decision is genuinely interesting: spending your 10 on a low card wastes it, but holding it too long may mean never using it.
