Runi's Math Castle

Runi's Math Castle is a math game for K–5 children, with number and word matching, addition and subtraction, and optional multiplication and division. You solve questions in a castle, earn Stars for correct answers and take on brain teasers and mini-games. Older children and adults can also play the brain teasers.

Math challenges

Choose Addition, Subtraction or Word Match, then turn on Multiplication or Division when you are ready. You can also practice reading analog clocks by enabling Time. Random mixes question types, while the Math Magical Maze offers any of the math modes you have selected. Set the number range anywhere from -9999 to 9999.

Navigate through math rooms, dodge spikes and answer questions to earn Stars. Stars reset each day, giving you a new daily high score to pursue. The game also tracks high scores for Stars and each mini-game.

Mini-games and rewards

The mini-game arcade includes Memory, Tic-Tac-Toe, Dance Party and Spire Run. Memory Match starts with 4 cards and adds more, up to 18, each time you clear the board. Spire Run gets faster and harder the longer you play, while Dance Party asks you to remember longer sequences of moves as it continues.

Spend Stars to unlock skins and mini-games, or save them as you work toward a higher daily score. The game includes 9 skins.
