FENER: Light Puzzle

About this app

One room. One light. Three questions. FENER is a calm puzzle game built on the geometry of light. Walls cast shadows; you place the light, block it, or hide from it. THREE CHAPTERS • LANTERN — place lanterns, leave no corner dark • CURTAIN — draw curtains, cut the protected ones off from the light • HIDDEN — predict the shadows while the lights are off, then flip the switch WHY FENER? • Endless levels, each generated by algorithm with mathematically guaranteed solvability • Levels are identical for everyone: your level 23 is your friend's level 23 • A fair star leaderboard on Game Center • Fully offline; no ads, no accounts, no data collection • No timers, no penalties — just you, the light, and the shadow • Subtle haptics and a quiet soundtrack A five-minute break or a long evening. Light is a gentle teacher.

The rooms have changed shape. NEW ROOMS - L, T and U shaped floor plans; columns in the middle, fins reaching in from the walls, and bevelled corners - Diamond and triangular obstacles bend the light in new ways - Every 10th level brings a signature room: one large block at the centre, a corridor around it TWO NEW LIGHTS IN HIDDEN - Patrolling lantern: the light no longer stands still — it travels back and forth along a rail. You must stay unseen at every moment of its round. - Two phases: the lights split into orange and green. Each dot must hide only from the light of its own colour. DAILY ROOM The same room for everyone, every day, in a different chapter each time. A streak leaderboard on Game Center: how many days in a row? Also fixed: dragging dots no longer feels sticky.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
