Card Duel is a free digital-only game included in the Osmo Math Wizard app. In Card Duel you can play against AI opponents in a friendly game of cards and brush up on equations and comparisons. Use the gems you win to buy power ups and build your deck!
The Card Duel game can be accessed from the Osmo Math Wizard app by tapping on the Blue Brew Cafe. For reference, Card Duel does not require the Osmo base, reflector, or any game pieces, so you can play it at any time.
We have instructions for the Card Duel game on page 6 of our PDF guide to Sky Castle.
