Lanterna Grid
Read full descriptionHide full description
Lanterna Grid is a quiet logic puzzle about light. Every grid is split into coloured regions. Place one lantern in each region so that no two lanterns share a row or a column - and no two ever touch, not even at a corner. That is the whole game. There is nothing to learn beyond those four rules, and everything to work out. No guessing, ever. Every puzzle has exactly one solution and every solution can be reached by pure deduction. Each one is verified twice before it ships: once by an exhaustive solver, and once by the same reasoning engine that writes the hints. - A new daily puzzle every day, the same grid for everyone - 112 puzzles across six packs, from gentle 5x5 grids to nine-by-nine at its meanest - Hints that teach - each one names the deduction you could have made, and why - One free hint every day - Timer, stars and best times for anyone who wants the pressure, ignorable for anyone who does not - Plays completely offline - Dark and light themes, region labels for colour-blind players, haptics you can turn off No accounts. No sign-in. No subscriptions or in-app purchases. Your progress stays on your device. Lanterna Grid is free and supported by ads. They stay out of the way: never on the board, never during a puzzle, and a short one only between puzzles.
