Rack up big fun as you race to put 10 cards into sequence: low number in the front to high number in the back. Sound simple? It is-with a solid strategy, concentration and a little luck! Whoever yells Racko first ends the round and earns the most points! Other players score points but only for cards they have in sequence. Scoring is tricky so it challenges kids to add and multiply. Includes 60 cards, draw/discard tray, 4 card racks. For 2 to 4 players.
