Bounce on a trampoline and spin in the air. Land upright every time or it's over.
Tap once to start bouncing. From then on the trampoline launches you upward automatically every time you land.
While you're in the air, hold your finger on the screen to spin clockwise. Release to let momentum carry you. The spin keeps going slightly after you let go, so plan your release.
The instant you touch the trampoline going down, your body must be upright (within a small tolerance). If you are, every full rotation you completed in that flight counts as a point and the next bounce throws you a little higher. If you're tilted, you crash and the run ends.
Goal: stack up as many clean flips as you can before crashing.
Treat the spin as a budget, not a target. The trampoline gives you a fixed flight time per bounce, and your spin rate while holding is also fixed — so the number of full rotations you can fit is bounded by physics. Releasing your finger slightly before vertical lets the residual spin coast you the last few degrees into perfect alignment, exactly the way real gymnasts ease out of a flip before sticking the landing.
The bounce gets higher each time you nail a landing, which is the trap. More airtime tempts you into one more rotation, but the extra fraction of a turn is where most runs end. A safer growth path is to commit to the same flip count for two or three bounces in a row, get a feel for the new height, and only then push to one more. Greed at the wrong moment costs the whole stack.
