Description by Allerton Apps (from the App Store)

Swipe. Roll. Crush the rocks.
Boulder King is a relaxing, brainy swipe puzzler where one move can make—or break—the run. Glide your boulder across the board, collide with rocks to smash them, and use clever routes to clear each level without rolling off the edge.

Simple to learn: swipe up/down/left/right to move.
Satisfying to master: use portals, dash lanes, and locks/keys to solve trickier layouts.

Why you’ll love it
• Pure puzzle flow: no timers, no energy—restart instantly and try again.
• 40 handcrafted levels: a complete arc with a celebratory final screen.
• Endless Mode — pick Easy / Medium / Hard / Impossible for a fresh, solvable puzzle every run.
• Crisp feel: smoother movement, subtle rolling SFX, and a gentle nature soundtrack (toggles included).
• Fair monetization: optional Remove Ads upgrade; watch a rewarded ad or purchase hints if you get stuck.

Swipe smart, plan your path, and become the Boulder King.
