Lumino City — a BAFTA-winning handmade paper-and-card puzzle, a craft miracle whose puzzles fight the 4+ kid it invites
State of Play, 2014. A ten-foot model city built from paper, card and wired bulbs, then filmed. $4.99, no IAP/ads/online. Seam: App Store 4+ but CSM 10+ on difficulty — a top-of-band (7–8) co-play, not a hand-it-over.
State of Play Games (UK indie), 2014 (Win/Mac; iOS 2015; Android 2017). A point-and-click puzzle adventure — a girl, Lumi, hunts for her grandad — whose entire world was built as a ten-foot physical model from paper, card, miniature lights and motors, then photographed. $4.99 one-time, no IAP, no ads, single-player, offline. BAFTA Artistic Achievement winner; Steam "Very Positive" (721/843); App Store 4.7★. The seam, on a 2–8 site: the App Store stamps it 4+, but Common Sense Media rates it 10+ — and the gate is difficulty, not content (CSM marks Violence, Sex, Language and "Products & Purchases" all "Not present"). The surface is a genuine handmade artifact; the obstacle is a photographic UI where a kid can't tell scenery from button, plus unskippable animations and obtuse tap targets. Honest fit: top of our band (7–8) with a parent reading the in-world manual — not a hand-it-over.
