Pistonio

A cozy 3D puzzle about pistons. Tap a piston and it fires, shoving whatever stands in front of it — your job is to push the golden cube onto the goal plate in as few moves as you can. Sticky pistons pull blocks back, pressure plates open gates, conveyors shift everything after each move. 84 handcrafted levels across five planets, plus a fresh puzzle every day. Clear a level and you earn a chest, and inside the chests live musicians: seat twelve of them on an island and it plays a whole song of its own.
