Beacon Grid
Beacon Grid is a daily logic puzzle that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.
Place one beacon in every row, every column and every coloured region, and no two beacons may touch, not even at the corners. Each day brings the same 6×6, 8×8 and 10×10 boards for everyone, plus a 7×7 practice board, and every board has exactly one solution. Finish without a wrong beacon to earn the No guesses badge.
How to play
- Tap a cell once to mark it empty, twice to place a beacon
- One beacon in every row, every column and every colour
- Beacons may not touch, not even at the corners
- Finish without a wrong beacon for the No guesses badge
The game shows these steps as you play, the first time.
Controls
- Tap once to mark a cell empty, twice for a beacon, again to clear
- Keyboard: arrows and Space
Tips
- Red marks a clash between two beacons, not a wrong cell. A single beacon in the wrong place looks fine until its row, column or colour runs out of room.
- The badge is checked a second after each placement: a beacon put down off the solution and cleared within that second does not count against No guesses.
- Use the × mark to rule cells out. Tap once for ×, twice for a beacon, and the keyboard's X key toggles a mark without cycling through a beacon.
How does the streak work?
Finish all three of the day's boards, 6×6, 8×8 and 10×10, and the day counts. Do that on consecutive days and the streak grows; miss a day and it starts again at one. The practice 7×7 board is random and does not count, and the start card shows which of today's boards are done.
What earns the No guesses badge?
Finishing a board without ever placing a beacon on a cell outside the solution. Empty marks are free, and a correct beacon that clashes with a wrong one does not count against you; only the wrong one does. The end card shows No guesses or counts the wrong beacons, and a daily board remembers a clean solve.
