Reaction minigame
Jetpack
Fly the jetpack robot as far as you can, dodging obstacles.
▶ Play Jetpack — free, no installRoblu straps into a jetpack and the world starts scrolling. Crates, crystals and scrap towers drift in from the right — some standing alone, some stacked into piles you have to climb over or duck under.
The twist is the fuel tank. Thrusting drains it, and it does not recharge on its own: the only refill is flying into one of the fuel canisters that float through the level. Run dry at the wrong moment and gravity decides the rest.
How to play
- Tap to jump off the ground, then press and hold to fire the jetpack and climb.
- Release to drop — weave through the gaps between obstacle piles.
- Watch the fuel meter at the top: thrust drains it, and only canister pickups refill it.
Modes & difficulty
In Roulette, surviving the 15-second round is a win — higher difficulty means tighter spawn timing, taller crate piles (up to five high) and a leaner starting tank. In Arcade, Jetpack runs endless: no timer, a live distance readout, and the run only ends when you crash. Your best distance is saved on your device.
One tip
Short bursts beat long burns. Feather the thrust to hold a height band instead of rocketing to the ceiling — and treat every fuel canister as mandatory, even when the detour looks risky.
