Subway Map
A transit line lights itself across a night city map then goes dark; redraw it from memory in one stroke to grow your own network.
Sugar Prism
/ Refract 50 original desserts through a color prism and reveal the one that connects three moods.
Sugar Stage Timing
Soft ball, hard ball, hard crack — a few degrees apart and a different sweet entirely
Suitcase Constellation
/ Pack 50 school essentials through a rotatable suitcase puzzle and reveal a shareable packing constellation.
Suns & Moons
A 60-second logic grid: fill every cell with a sun or a moon so each row and column has three of each, never three in a row, and every = or × clue holds. Tap to cycle, beat the clock, share your time.
Sunset Spill
Tap to pour sunset acrylics onto a canvas and drag to tilt it — the paint runs, laces and cell-blooms, then self-levels into your own abstract piece.
Sushi Stack
Sushi pieces slide across the counter; tap to drop each one on the tower. Overhang is sliced off and falls away, perfect drops flash and regrow a sliver.
Swamp Sphere
A sealed glass mangrove swamp that cycles its own weather; each visit you may introduce one seed, stone, creature or spring, and the ecology runs while you are away.
