Fast Fun™ Whac-a-Mole™ Stack-a-Mole™ is a fast-paced, 2-player game and is a shorter, simpler version of the original Whac-a-Mole™ game. The game features a stacking mallet and colored cups. To play, flip a card and use your mallet to match the colors on the card with colored mole cups. You'll "whack" the cups with your mallet to stack them up in order. But hurry—your opponent is trying to stack theirs first! Be the first to stack all the cups in the correct order and you win! It's mallet-smacking, mole-stackin' excitement! It's "Fast Fun" that kids as young as 3 can enjoy. For 2 to 4 players. Colors and decorations may vary.
