Behind Junction Nine is a published mathematical result: in a 3×3 grid where any rectangle can be spun 180 degrees, every arrangement can be returned to order - and never in more than nine spins. We designed the puzzles and independently calculated the fewest spins each one takes. See if you can match the minimum. HOW IT WORKS Spin any rectangular section of the grid 180°. Remember - squares count as rectangles. A move can shift several pieces at once, so fixing one connection can disrupt another. Rotate tiles until every connection lines up. Then keep going: can you match the fewest possible spins? Every puzzle has a proven minimum.

Slimbo is a physics puzzle about goo, gravity and gentle chaos. Drop soft jelly blocks into a stone pit and watch them squash, sag and settle. Nothing snaps to a grid — every piece leans on the ones below it, so your tower is only as good as the physics holding it up. The goal is simple: reach the lollipop. Getting there is not. • 18 handcrafted sites, each with its own trick • Soft-body jelly that stretches, tears and collapses for real • Hooks, ledges, thorns — and a hungry little bug that eats your work • A winged candy that hops away just as you close in • A hint when a site refuses to give in • No timers, no lives — think as long as you like One finger is enough. Tap to rotate, drag to drop, and let gravity do the rest.
