Poucave!

Poucave, the game where you have to throw your buddies at the right moment. It's playtime and the Mistress has limited patience. On your turn, you must add a card from your hand to the yard. The cards add up; as soon as a player feels that the last card played gives a total that exceeds the Mistress's threshold, he must seize the opportunity to rat out his buddy. A snitch who is right scores points, but conversely, a snitch who tells on his comrades too early will give them points. —description from the publisher (translated)
