About What's Under Your Bed?, from BoardGameGeek:
What's Under Your Bed? is a fast-paced, easy-to-learn card game where players compete to build the biggest pile of monster cards by the end of the game. Each turn, players play a card from their hand, attempting to match a monster in the center or on another player's pile. A match allows them to claim that pile, while unmatched cards create new open piles for future turns.
Adding to the chaos, special action cards-Steal, Split, Switch, and Rotate-let players shake things up by swiping piles, splitting stacks, or forcing players to swap their hard-earned collections. Every round, the stakes get higher as the deck dwindles and players scramble to secure the largest monster hoard.
With simple rules, strategic depth, and plenty of opportunities to mess with your opponents, What's Under Your Bed? is perfect for families, casual gamers, and anyone who enjoys quick, competitive gameplay. Once the final card is played, the player with the biggest monster pile wins!
