10 Million Bounces / 一千万次反弹

One ball. One bounce. A tunnel that keeps growing.

10 Million Bounces is a single-player incremental mining game. Begin in a small clearing, choose a launch point and direction, and release. Your balls keep bouncing into ore and opening new passages. Send newly earned balls down different routes and turn a quiet starting point into a busy mining site.

Aim, launch, and let your swarm keep working

Hold left-click in an open area, drag to aim, and release. Launch one ball, ten balls, or all available balls of the selected type. Press Space to launch again in your last direction. Pan and zoom across the mine to find your next launch point.

Six ball types to upgrade and evolve

Normal, Swift, Heavy, Split, Ember, and Lightning balls each have their own role. Every type has six upgrade levels, followed by a separate evolution choice.

• Rainbow: Learn traits from nearby moving special balls and retain multiple abilities at once.
  
• Blink: After flying for more than half a second following a bounce, blink along the current direction to the next collision.
  
• Siege: Destroy the ore tile you hit and keep piercing forward.
  
• Brood: Create temporary balls that inherit the Normal ball's upgrade and evolution state.
  
• Wildfire: Ignite ore and spread fire to surrounding tiles.
  
• Thunderstorm: Strike every target within range with lightning at the same time.

Choose your order of growth

Break ore to earn experience. On level-up, choose from up to four rewards to unlock ball types, improve their abilities, or evolve them. Level-ups also grant unassigned balls, which you can invest in any unlocked type. Build up direct damage first, or bring splitting, fire, and lightning together.

Keep opening paths through a vast mine

Explore a 4,096 by 4,096 grid with around 16.7 million tile positions. Ore colors indicate different durability tiers. As your swarm opens passages, more of the surrounding mine comes into view.

Switch between English and Simplified Chinese, follow the opening tutorial, adjust sound effects, pause with Esc, and continue your excavation with local autosaves.
