CollectO!

Players race to collect either four cards with the same number or five cards of the same color by drawing from a shared display row. Each turn, take a card and choose whether to keep it or place it in the display for others to potentially claim. The tension comes from the "O!" rule: when one card away from winning, players must shout "O!" or forfeit the game if caught. This creates a delicate balance between progressing toward victory and revealing your position to opponents. Action cards add strategic depth - steal cards with Thief, peek at opponents' hands with Wise Vision, or protect yourself with Defense cards. The Joker acts as a wild card for any color or number, while Penalty cards can derail your progress. The scoring system rewards finishing order across multiple rounds, with points allocated based on player count. Success requires careful hand management, timing your "O!" declaration, and using action cards to disrupt opponents while protecting your own collection. —description from the publisher
