Short description
Turn the rings, drop the balls in the slots, and keep up. A one-finger arcade game for iPhone.
Long description
Concentrigasm is a fast, one-finger arcade game about steel balls and spinning rings.
Balls roll down a winding track towards a stack of concentric rings. Each ring has a few gaps, and each gap holds one ball. Drag a ring to turn it. A ball only drops into the ring you're turning, and only once a gap has stayed lined up underneath it. Fill every gap in the innermost ring and it collapses, the other rings move in, and a new ring arrives on the outside. Clear rings back to back to build a chain.
All the while, more balls keep coming. If the queue on the track reaches the red marker, the game is over. And the better you score, the harder it gets.
Pay once and play: no adverts, no in-app purchases, no tracking.
