Monsters are marching on your castle. Build towers along the road, pick a card every level, and stand your ground all the way to the boss.
Every level up deals you three cards. Pick one, place it, and build a defense that's all yours.

Archers, cannons, lightning, frost and stranger things. Merge matching towers to rank them up.

Your hero walks onto the road and fights beside your towers, with a special power all their own.

Meteors, blizzards, walls, extra road, moving a tower. Every pick changes the match.
Straight from the game on a phone.





The ogre, the hydra that grows its heads back, the Storm Roc, the Tide Kraken, the Pumpkin King and more.
