Skulduggery!

Skulduggery! is a fast-paced take-that style trick-taking game. Players send adventurers into an unknown dragon's lair in hopes of making it out alive with the most riches. Use the human's ability to peak at the dragon card, the dwarf's ability to steal gems, the halfling's ability to swap cards, and the elf's ability to double the value of cards in play. Each round uses a different dragon's lair, so you need to be as crafty as you can to win. Plays in 30 to 60 minutes and up to 8 players.
