Bounce shooter guide
Boulder Blitz: aim, bounce, and chain the cracks
Boulder Blitz is a bounce shooter. A cannon sits at the bottom of a tall arena; a wall of blocks presses down from the top. Aim, launch, and the boulder bounces off the walls. Each hit cracks a block; broken blocks explode and damage their neighbours, so chains can cascade across the whole wall. The wall creeps down with every shot — clear it before it lands.

What is Boulder Blitz
Boulder Blitz is a single-boulder shooter. The wall starts at the top of the arena and creeps down a row every few shots. The boulder bounces off the side walls and the ceiling; every time it touches a block, that block loses a hit point. When a block breaks, it explodes — a damage wave hits every block within a radius, and any block that breaks from that wave explodes too. One well-aimed shot can chain a cascade through the whole wall.
Block types
| Block | Hit points | Effect on break |
|---|---|---|
| Normal | 1-3 (number on face) | Explodes, damaging neighbours |
| Bomb | 1 | +100 points and a big blast radius |
| Star | 1 | Fires a second boulder |
How a round works
- Press Launch to start. Aim by dragging across the arena.
- Release (or press Space / S) to fire the boulder.
- The boulder bounces and cracks blocks. Broken blocks chain-explode.
- After every few shots the wall creeps down a row.
- Clear the whole wall to advance. If any block crosses the danger line, the round ends.

Frequently asked questions
Quick answers to the most common questions about Boulder Blitz.
When does the round end?
The round ends when the wall crosses the danger line — any block remaining below it after a drop. In timed mode it also ends when the 90-second clock runs out.
How do chain explosions work?
When a block breaks, a damage wave hits every block within roughly one and a half cells. Any block that breaks from that wave explodes too, so damage cascades. Bombs and stars trigger the same chain.
What do the symbols on blocks mean?
A number is the block's hit points. The bolt symbol is a bomb worth +100 on break. The star symbol fires a second boulder automatically.
Can I control the boulder mid-flight?
No — once launched, the boulder bounces on its own. Aim is everything, which is why the aim line and the bounce physics matter more than reflexes.
