Meet Tile Shift. A familiar puzzle with room to think.
Play Tile Shift ↗Learn Lantern Grid, one idea at a time.
Start with the rules, try the same board, then work toward an independent challenge. Each lesson has its own worked example.
- 1Beginner rules ↗
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.
- 2Solving strategy ↗
Compare a brightening move that blocks a numbered wall with a forced seven-bulb solution. A fixed board, candidate table and straight-line source checks make each deduction reproducible.
