About the Game

Welcome to Castle V Castle, a single player turn-based card battler where you tear down the enemy castle brick by brick!

Spend resources to play cards, boosting your castle or knocking your opponent down a floor.

Win by growing your castle to the height of 25 meters, or reducing the other player to rubble. It’s a race to the top!

Defeated castles spawn reward cards you can take with you into the next fight, ranging from permanent stat upgrades to single use items. Curate your deck over the course of a run and see how far you can get! Earn XP at the end of each run and unlock gifts - new modes, reward cards and more!

Test your skills in the daily challenge mode, a single battle where both sides start with completely randomized stats! Every player gets the same daily challenge around the world. Outbuild your opponent and build up a Wordle-style winning streak!
