Exacto

Can you figure out which two cards match? The combination will differ each time you play! Exacto contains 15 large, thick cards, each having a pair of holes in it, along with eight colored circles on the front side. To play, shuffle the deck, then lay out two cards, one face up with the colored circles visible and the other face down with only the holes visible. The first player looks at the cards — without touching them or using any tool other than their eyes — then names the two colored circles they think are the same distance from one another as the holes on the face-down card. They then take the face-down card and overlay it on the face-up card to see whether they're correct. The match will be perfect, and if they're correct, they keep the face-down card as a point and return the face-up card to the bottom of the deck; if they're wrong, the next player names two colors, etc. The next round starts with the player to the left of whoever most recently won a point. When only one card remains in the deck, the game ends, and whoever collected the most cards wins. Alternatively, play until someone scores their third point.
