Lantern Logic

The old town is falling asleep… but its lanterns still glow. Your job: put them out, one alley at a time.

LANTERN LOGIC is a calm logic puzzle inspired by the classic "Lights Out": tap a lantern and it flips together with its neighbours. Turn them all off to end the night.

A SIMPLE PUZZLE WITH REAL DEPTH
• Tap, flip, observe: every move changes the district.
• The optimal number of moves is shown — match it to earn 3 stars.
• No timer, no lives: play at your own pace.

10 DISTRICTS, 7 PATTERNS
Each district of the town changes the rule:
• Cross – the lantern and its 4 neighbours
• Diagonals – its 4 corners
• Star – all 8 neighbours
• Row & column – the whole row and the whole column
• Hexagons – a 6-neighbour tiling
• Knight – chess knight jumps
• Mixed – every lantern carries its own pattern
Then come caged lanterns, which only their neighbours can turn off.

300 LEVELS, ALL PROVEN SOLVABLE
From 3×3 to 9×9, every level is generated and then verified by a mathematical solver: a solution always exists, and the hint shows you a lantern from the optimal solution.

A SOOTHING NIGHT
• Night atmosphere: starry sky, old-town rooftops, amber halos
• Gentle music (ney, santur, crickets) and synthesized glass sounds
• High contrast and reduced motion options
• English, French and Arabic

OFFLINE
The game works without a connection. It contains ads (a discreet banner, spaced interstitials, and an optional video to earn hints).

Good night — may the town sleep well.
