The longboats have returned from their raids, and in good Viking style, there is a fight over how to split up the treasure. In Clash of Vikings, players play as Vikings in an arena trying to gather the most treasure. Each player has a deck of ten cards with different possible actions. On a turn, a player plays two of the three cards they hold. For each card, they must declare (without revealing the card) what the action is, and other players must decide whether or not to call a bluff or not.
