Dungeon Ball

From BoardGameGeek:

While the monsters wait for more heroes to wander into the dungeon to meet their untimely end, they bide their time by playing games they learned through torturing adventurers. For the most part, they understand how to play, but they're a little hazy on things like the rules against cheating and whatnot. Dungeon Ball gives 1-2 players a fast-paced, arcade style experience as they try to outwit and outscore each other over the course of two halves of play. The player with the most points at the end wins. Games take around 45 minutes. -description from the designer
