Castle Kaboom

The fleet is coming. Your walls won't survive. Build anyway. Castle Kaboom revives a legendary arcade formula and rebuilds it for the touchscreen: part tower defense, part artillery duel, part falling-block puzzle — all under one merciless timer. CLAIM — Choose your castle on a procedurally shaped coastline. ARM — Drag cannons inside your walls. Every castle you enclose grants more guns. BATTLE — Hold a finger on the sea and your batteries volley at the crosshair. Sloops swarm, galleons pound your walls, ironclads shrug off hits, and fire ships beach themselves to scorch your land. REBUILD — Your walls are rubble. Drag and rotate puzzle pieces to seal a castle before the clock hits zero — or lose a banner. Lose all three and the keep falls. Between waves, spend plundered gold on extra cannons, powder kegs, fresh banners — and lasting upgrades for your guns and walls. • 8 voyages with escalating fleets — then the Endless Tempest • 12 Trials of the Keep: hand-built challenges with twisted rules • Three difficulties, from Calm Seas to Storm Tide's black armada • Upgrade your arsenal: Bronze to Royal gunnery, Stone to Obsidian masonry • Combo chains, three enemy fleet tiers, star ratings, unlockable progression • Game Center: global best-score leaderboard and four achievements • Crunchy haptics, synthesized retro audio, and a sea-shanty chiptune • Premium and private: no ads, no tracking, no data collection, works offline One more wave.
