Lantern Grid
Place bulbs so every white cell is lit, numbered walls have exact neighbours, and no bulb shines on another.
A good move starts with an idea.
Lantern Grid for beginners: place bulbs, read walls and light every cell.
Play a fixed first illumination puzzle, follow a six-bulb solution, and test why exact wall numbers alone do not finish the board. Includes reversible mistakes and keyboard controls.
Lesson 3Practice challengeShade Link practice: predict the counts and protect the connector.
Try a new fixed board, fill a three-count prediction ledger, and test an extra shade that splits a valid path into three groups. Reveal the full deductions and recovery steps after trying.
Lesson 2Solving strategyShade Link strategy: use adjacent pairs, then protect the kept paths.
Use a different fixed board to force a third copy out, reject choices that isolate kept cells, and compare five checked deductions with reproducible wrong branches.
Take your time.
That’s part of the fun.
Our puzzles have no countdowns, entry fees, or public leaderboards. Try a move, notice what changes, and make the next one a little more deliberate. The guides explain the rules and the reasoning, with examples you can try for yourself.
