One Shot, Straight Up
The cannon only fires vertically. You choose where it stands and when it throws — the whole game lives in those two decisions.
One-thumb precision timing
Lead the swing. Pin the zone.
A cannon rides a rail along the bottom and throws straight up. Above it, a target bar swings left and right carrying zones you have to pin. Blockers cross the lane between them. Knives are limited and the board is on a clock.
How it escalates
The opening boards are the swing alone — just learn the lead. Then blockers arrive, the zones narrow, the swing speeds up and the clock tightens. Clear board 6, 11 or 16 and you keep the right to start there.
Gameplay overview
The cannon only fires vertically. You choose where it stands and when it throws — the whole game lives in those two decisions.
The bar swings fast through the middle and hangs at the ends, so the edges are the easy shot and the centre is the hard one. You work that out yourself; nothing tells you.
Bars traverse the lane between you and the target. A knife that hits one embeds in it and rides off the side of the screen, along with the throw.
Will my column still be clear when the knife gets up there, and will the zone be over it when it arrives? Every throw has to answer both at once.
You cannot just throw until something lands. Knives run out and the board runs down, so a wasted throw costs more than the throw itself.
Clear board 6, 11 or 16 and you permanently unlock starting there. Earn sparks for every board and spend them before a run on knives, time or a life.
How it works
Drag anywhere along the bottom to slide the cannon into the column you want.
Watch the swing and the blocker lanes, and wait for the moment your column is clear and the zone is heading over it.
Lift your thumb. The knife leaves instantly and sticks where it lands — in the zone, in bare bar, or in the blocker that took it.
Pin every zone to clear the board. Then do it again, faster, with less of everything.

Frequently asked questions
Drag anywhere along the bottom to place the cannon, then lift your thumb to throw. It is one continuous gesture, so you can hold a column and wait for the swing as long as the clock allows.
It hit a blocker. Those are the bars sliding across the lane between the cannon and the target; a knife that hits one embeds in it and rides off the side of the screen. They are big, slow and fully visible, so getting caught is always a shot you could have chosen not to take.
No. Clearing board 6, 11 or 16 permanently unlocks starting from there, and you choose where to begin before each run. A lost run never means grinding an opening you have already mastered.
You earn sparks for every board you clear and spend them before a run on one of three things: an extra knife on every board, extra time on every board clock, or an extra life. They map onto exactly the three things a board can run out of.
Every board is on a clock, and it is budgeted per zone — boards carrying more zones get more time. Running out of clock costs a life, the same as running out of knives.
No. Rebound is fully playable offline. The game sends anonymous gameplay statistics when it can, and you can turn that off in Settings under Anonymous data.
