About this game

Goblins are climbing your castle wall. You have a cannon, and gravity.

Drag to move the cannon along the battlement. It fires on its own, and every cannonball bounces down the wall's iron studs, bonking goblins and knocking them back down. Knock one clean off the wall for double XP!

ENCHANT THE WALL
Every level-up deals you three cards. Turn studs into fire, frost, splitter, powder, gold, bumper, storm, giant, seeker or lucky studs, and the wall itself becomes your build. Pick the right pairs and your cards evolve: Inferno, Hydra, Cluster Bombs, Tempest, Jackpot and more.

150 CASTLES IN 30 WORLDS
From Meadow Keep to the Throne of the Goblin God: fairy forests, desert palaces, a coral kingdom, steam-powered cities, misty mountains, candy castles, a lost valley of dinosaurs, a circus, a wizard academy, the wild west, a giant's garden, the frozen north, marble temples, a mirror realm, the land of dreams, the savanna, the underworld, goblin war factories, golden clouds and outer space. Every castle has its own wall, goblins and boss.

CASTLE RULES
Later castles change how your balls fly: crosswinds, underwater walls, dark nights, sliding or turning studs, spring studs, sticky webs, slippery ice, low gravity, heavy air, fog, earthquakes, portals, currents, molten studs, lightning storms and updrafts. Clear a world to win its relic, a bonus you keep for good.

300+ KINDS OF ENEMIES, 150 BOSSES
Shield goblins, healing shamans, bombers, slimes that split, ghosts, moles that dig under the wall, gobblers that swallow your balls, monsters that grow as they climb, goblins that get angrier the more you hurt them, and bosses like the Sphinx, the Kraken, the Minotaur, the Mothership and the Goblin God.

HEROES, WEAPONS, MINIONS AND PETS
- 30 heroes, each with a tap ability, like Arrow Storm, Deep Freeze or Dragonfire
- 53 weapons, from the Twin Barrel to the Gravity Cannon, each leveled up with coins
- 53 minions that fight beside you on the battlement
- 25 pets, 30 relics, an Armory of permanent upgrades, and talents

MODES
- Endless Siege: wave after wave, a boss each wave
- Daily Challenge: a new castle, weapon, hero and rule every day, with medals
- Boss Rush: every boss you've beaten, back to back
- Castle Trials: a tougher rematch for every castle you 3-star

ALWAYS SOMETHING NEW
A new event every week, each with its own track; a season pass every 4 weeks; 8 holidays through the year, each with its own pass and skins; a bonus every weekend; daily goals and deals, a login calendar, free gifts, 121 trophies, a Monster Book to fill, and more than 100 cannon and cannonball skins.

FAIR TO PLAY
Every castle can be won without paying. Ads are rewarded only: you choose to watch one for a reward, and you never get a forced ad. Optional purchases include gem and coin packs, passes, bundles and Premium.
