A randomized board game that tasks the player to knock out castles by landing on a castle tile. Players can move from tile to tile using math multiples. 1. Select a beginning number. 2. Roll the die to start the game. 3. Find a tile that is a multiple (add, subtract, multiply or divide) of your number and the number rolled. 4. The goal is to land on a Castle tile and turn it to rubble! 5. The game ends when no more Castle tiles exist. 6. Your score is the number of rolls you've made and incorrect penalties* added. A lower score is better! * Penalties are 3x the number of incorrect answers.
