This quick to learn fun game will soon become a family favourite. Players are dealt four cards: two of which they know and two of which they don't. Players try to find out the amount of their unknown cards and to have the lowest hand. If you think you have the lowest score call Rat A Tat Cat and hope everyone has a higher score than you. Great game for all ages to play together and it practises those math skills (but don't tell the kids!) 2 to 4 players, ages 6 and up.
