愚者の棺 (Gusha no Hitsugi, "Fool's Casket") is a test-your-luck game from Polygonotes. A band of heroes have found an ancient treasure horde, but before they can take any of the prizes away they'll have to get by the ghosts that haunt it.
Each round you'll try to get a piece of treasure by drawing from the ghost deck. If you draw a ghost with the same element as the treasure you can keep it, but if the fourth ghost of a type comes out it'll play a trick. Exactly what the trick does varies by type, but it includes swapping your treasure with the top of the deck, swapping someone else's treasure, or even flipping the deck upside down.
You can choose what treasure you go after, so will you go for high points, the safe bet, or try to interfere with the other players? You can avoid ghost types that are about to play a trick on you, or you can go after them to trigger the trick on purpose.
The first player to ten points wins the round and escapes the tomb with their treasure - and their life!
