Helicopter is a free online one-button cave flyer in the spirit of the classic helicopter game: your chopper always drifts forward, and the only control is altitude. Hold the mouse button, hold a tap, or hold Space to climb; let go and gravity pulls you down. On a phone, hold anywhere on the cave or the bar under it. Thread the shrinking cave, duck under (or hop over) the floating blocks, and fly as far as you can without clipping a wall. Distance is the score. Crash and you start a new run instantly — that is the whole loop, and that is why it is so hard to put down.

The secret is small corrections, not panic holds. A long hold sends you into the ceiling; a long pause plants you in the floor. Aim for the middle of the tunnel and start turning early — the helicopter has momentum, so reversing from a full climb takes a beat. Blocks always leave a gap above and below; pick a side and commit. The cave gets tighter and twistier the farther you go, and blocks show up more often, so a run that felt roomy at 200 gets mean around 1,000. Your best distance is saved in this browser. Hold, release, and see how far you can fly in this free helicopter game.
