The dragon was slain, leaving behind a treasure to fight for.
The players are wizards, fighting to claim the most gold from the Dragon's pile.
The players have cards depicting various well known D&D spells, and each card shows a Rock-Paper-Scissors gesture that the player must make to cast, while pointing at another player as the target of the spell.
All players choose their spells simultaneously.
The spells can move the wizards closer or farther away from the treasure, and can affect the game state in other ways as well.
The first player to collect 25 gold wins.
