Frequently asked
How do I shoot? Touch anywhere, pull back and release, slingshot style. The pull length sets the power; pulling left or right turns the cannon the other way. Watch the wind arrow at the top.
How do I win? Shatter the enemy castle's glowing heart. It does not matter how much of the castle is still standing.
Is the game free? Yes, and there are no ads. Every mode, castle piece and heart type is earned by playing. The Shop sells optional cosmetics (castle skins, cannonball trails, fireworks, heart gem colours, banners and the Supporter Pack); they only change how things look, never how a match plays.
I bought something on another device. Open the Shop and tap Restore. Purchases restore on any device signed in to the same Apple Account.
Refunds. Purchases are handled by Apple. Request a refund at reportaproblem.apple.com.
How do I play with a friend? On the same device, pick Two players. Nearby, one device hosts and the other joins over the same Wi-Fi or Bluetooth, with no account needed. Over the internet, use Game Center matchmaking.
Leaderboards, achievements or online matches aren't working. Sign in to Game Center in iOS Settings, then relaunch the game. For nearby play, allow Local Network access for Keepfall in Settings › Privacy & Security.
How do I share my castle? In the builder, tap Share to send a castle code. A friend can paste it under Friend's castle on the menu.
When does the Daily Siege change? Every day; everyone gets the same siege, so scores are comparable.
