Press a pump and a jet of juice shoots up from that corner. A quick tap gives a small puff; press longer and the jet builds and reaches further, until the plunger bottoms out and you press again. Float every ring down over one of the floating pegs before the clock runs out. Posts are solid, and each holds just over half the rings, so you need more than one. Tilt with Q / E, or tap TILT and lean your phone. Each round adds rings and another peg, up to five.
