A daily logic puzzle to lighten your day.
Place lighthouses to light every cell on the grid. No two may share a row, share a column, or touch in adjacent spaces, not even diagonally. Simple to learn, surprisingly hard to master.
A new 8x8 puzzle every day at midnight PST, hundreds of hand-rated practice levels across four difficulty tiers, and an endless Unlimited mode against the clock. Build your daily streak and share it with friends.
GAME MODES
Daily Challenge
A brand-new puzzle every day at 12:00 AM PST, alternating between 8x8 and 9x9 grids. Solve it to grow your streak. Share your result.
Practice
Hundreds of puzzles across four difficulty tiers: 4x4 Noob warm-ups, 5x5 Pro grids, 6x6 Expert puzzles, and 7x7 Genius brain-burners. Every level is hand-rated by a constraint solver, so the difficulty curve is smooth and fair.
Unlimited
An endless run against a 60-second clock. Each puzzle you solve refills 20 seconds back on the timer, capped at 60. Puzzles get progressively tougher as your run climbs. How long can you keep the clock alive?
HOW TO PLAY
Every puzzle has the same four rules:
- Place exactly one lighthouse in each colored region.
- Beams shine the full length of the row and column from each lighthouse.
- No two lighthouses may share a row, share a column, or touch in adjacent spaces, including diagonally.
- Every cell must be lit by at least one beam.
If you get stuck, spend a hint to place the hardest remaining lighthouse. Hints come from optional in-app purchase packs, or you can watch a short rewarded ad for a free one.
WHY YOU WILL LIKE IT
Pure logic. Every puzzle has exactly one solution, reachable through deduction alone. No guessing required.
No ads in the way. Ads only appear when you actively tap to watch one in exchange for a free hint. Never interruptive.
Respectful of your time. No account required. No daily-login slot-machine. Just puzzles.
Beautiful and fast. A clean dark theme by default, with a light theme one tap away. Built to feel instant on any iPhone.

It tested my critical thinking and problem solving skills and I feel like Einstein after a few rounds. Training to become a quant and I feel a lot more confident after working through some puzzles
Super fun game!
