Light Toggle
by Nebulark Studio · Puzzle · v1.1.0
Light every paper lantern in a moonlit river garden. Each press flips a lantern and its neighbours, so plan your presses and match the solver's par for three stars.
How to play
- Light every lantern: a press flips it and its row/column neighbours between lit and dark.
- Pick a mode and press Play (or Continue a saved run). In Campaign, choose a board with the arrows above Play.
- Press order never matters and a second press cancels the first. Par is the fewest presses that light the board.
- Press/Par counts your presses; Stars shows the most stars still in reach. Par with no hint earns ★★★.
- In Diagonal Wind boards a press flips the lantern and its four diagonal neighbours instead; the caption says which.
- Undo (U), Reset (R) are free; Hint (H) rings one press of an optimal solution and costs 30 points.
- The Daily garden is the same for everyone each day; light it on consecutive days to grow your streak.

About Light Toggle
Light Toggle is a calm logic puzzle set in a night garden by the river. Tapping a lantern flips it and its four neighbours, lit to dark and dark to lit, and the garden is finished when every lantern glows. Press order never matters and pressing twice cancels out, so every board is really a question of which lanterns to press. Every board is made by scrambling a fully lit garden, so it is always solvable, and its par is the true minimum found by our linear-algebra solver. The Campaign has 30 boards from 3×3 to 7×7. The Daily garden is the same for everyone each day, and Diagonal Wind is a ranked chain of five boards where each press flips the corner neighbours instead. Practice deals a fresh random board whenever you like. Hints, unlimited undo and reset are always there, a live star meter shows what is still in reach, and a run in progress is saved so you can continue it later.
