Hop diagonally around a pyramid of 28 cubes: every landing changes a top’s colour, and when they all match the target the round is done. Later levels need two hops per cube or flip finished cubes back. Red balls bounce down, a purple ball hatches into a spider that chases you, a blue imp undoes your work (catch it) and a green orb freezes everything. Leap onto a floating disc to ride back to the top — and lure the spider off the edge. Free, no sign-up — play right in your browser.
