Bloops

From BoardGameGeek:

Bloops is a clever and chaotic card game where memory and attention make all the difference. Each player starts with a grid of face-down cards, memorizing only three of them to start. From there, the tension builds as cards are drawn, discarded, swapped, and secretly added. Every turn offers a choice: discard the card you just drew, or keep it and discard one of your own without looking at it. Special cards trigger immediate effects, allowing you to peek, force cards onto opponents, or even swap cards blindly. And at any moment, any player can jump in with a counter-discard… as long as they're confident they remember what's in front of them! Think you're winning? Say “Bloops” to trigger the end of the game. But be careful, a single forgotten card can turn victory into disaster! Bloops is perfect for players who love sharp memory games with a mischievous twist. -description from the publisher
