Hold to rise, release to fall. Fly through the cave!
Helicopter is the quintessential one-button flying game that has captivated players since its early Flash days. Hold down the mouse button or spacebar to make your helicopter rise, and release to let it descend under gravity. Navigate through an endlessly scrolling cave with randomly generated ceiling and floor obstacles that narrow and shift unpredictably. The moment your helicopter touches any wall or obstacle, the run ends. Distance is your score, and every meter counts. The simplicity of the controls belies the intense focus required as passage gaps tighten and your reaction window shrinks. Helicopter is a pure test of timing and nerve that remains one of the most addictive browser games ever created.
