Beacons is a calm, beautiful logic puzzle about lighting up the coast.

Each board hides one simple rule: place a single beacon in every row, every column, and every colored stretch of coastline — but no two beacons may stand next to each other, not even diagonally, or their beams would cross.

There's no luck and no guessing. Every puzzle has exactly one solution, and every solution can be reached by pure deduction — so a win always feels earned. Start with the smallest coves, watch each beacon rule out the cells around it, and feel the whole board click into place.

400 HAND-VERIFIED LEVELS
Work through 400 puzzles across four difficulties — Easy, Medium, Hard, and Expert, 100 each — that ramp up smoothly as your skills grow. Every single board is checked by a solver to guarantee a unique, logic-only solution before it ships. Clear a level to unlock the next, then come back to beat your best time.
