Let go before a dark ring turns under the ball. Bouncing on iron is safe.
How to play
Hold. Hold anywhere on the screen, or hold Space, and the ball smashes straight down through the rings.
Coloured rings break. Every ring the ball smashes through scores a point.
Dark iron does not. Smash into a dark part of a ring and the run ends. Let go in time: a bouncing ball is safe even on iron.
Fire. Keep smashing without a bounce and the fire bar fills. On fire, the ball breaks even iron for a few seconds.
Finish. Reach the gold ring at the bottom to clear the level. Each level is a taller tower that turns faster, and later ones have rings that turn the other way or swing.
Keyboard: hold Space or the down arrow. Esc opens the menu.
