In this outer-space themed game players select a card and compete in a battle - rolling the corresponding giant squishy foam asteroid-dice to try and score the highest number each round. The player with the highest roll at the end of the round takes all the cards (which indicate a number of points). When all cards have been played the player with the highest total score wins. Each round players pick a card and after a countdown reveal their choice to the others. If two players have chosen the same asteroid-dice they compete in a throw off; grabbing any dice from the middle and throwing it at the other player. The last person to get hit wins the asteroid they intended for the battle and takes the other players card, adding it to their total score. In the Battle phase, players roll their asteroid-dice in turn starting from the largest die (d20) to the smallest (d6). Players can attempt to use their dice to knock other dice and change their score. The player with the highest score at the end of the battle phase wins all the cards and adds them to their score. -description from publisher
