Castle Topple: Cannon Puzzle

Pull back anywhere on the screen to aim, then let go to fire the cannon. Hit the right block and the whole castle comes tumbling down — knock down every knight to clear the level.

New: 3D Siege — tap the 3D castle to fire the cannon. The bricks break apart and the castle crumbles. 10 levels to start, and you can drag to turn the view.

• 60 levels across 6 kingdoms: Meadow Kingdom, Stone Fortress, Ice Castle, Volcano Keep, Desert Palace and Sky Citadel. Each kingdom ends with a boss castle where the king is waiting
• Every kingdom brings something new: wood that breaks, stone that won't, ice that shatters and slides, TNT that explodes and sets off its neighbours, heavy gold blocks worth bonus points, and floating platforms and seesaws in the sky
• Real physics: blocks tilt, crack, slide and fall, so every castle collapses in its own way
• Simple controls: the farther you pull, the harder the shot. Slide back to where you started to cancel
• Knights fall when they are hit hard or drop from a height
• Puzzles, not luck: most levels take two to four well-placed shots. Clear a level in fewer shots to earn up to 3 stars
• Special shots unlock as you progress: Iron Ball (breaks through even stone), Bomb (explodes on impact, or tap while it flies) and Triple Shot (three balls in a fan). You get one of each free in every level, and when they run out you can watch an ad for another
• Out of cannonballs? Watch an ad for +2 and keep going right where you left off, up to twice per level
• Daily Siege: a new siege every day — keep your streak going
• Endless Siege: topple wave after wave of new castles and chase your best score
• Played in landscape for a wide view of the battlefield
• Pause anytime, and turn screen shake off if you prefer
• Available in 9 languages
