Goal: Bank the highest score before the competition closes. Only your best paid run counts, and every round is won by being the last bomber standing.

Movement: Use arrow keys, WASD, or the on-screen joystick to navigate the grid. You move one cell at a time.

Grenades: Press Space or Q (or the grenade button on mobile) to place a grenade at your feet. It detonates after 3 seconds, blasts in four directions, and chain reactions can light up the whole arena fast.

Rivals: Metal Bomber opens the fight and the other rival bombers join him. Early rounds are slower, then the rivals get faster, smarter, and more aggressive as the run goes on.

Power-Ups: Cracking soft crates can reveal power-ups. GRENADE UP lets you carry one extra grenade. FLAME UP extends the blast range of each explosion by one tile. BOOT KICK lets you kick grenades out of your path.

Rounds: Every cleared arena loads a fresh BlockBuster-style battle board. Winning rounds quickly is worth more, and every new round ramps up the pressure.

Run Format: Every paid run gives you 3 lives and 10 minutes. Squeeze every point you can before the timer runs out.

Persistence: If you leave mid-run, your active paid run autosaves and can be resumed later. Abandoning it burns that credit.
