About Arrow Web
In a copper-roofed wayfinder’s observatory, engraved arrows point across a glass signal chart. Light beacons so every arrow sees exactly one glowing target along its straight sightline.
Explore 180 original charts: sixty each at 5×5, 6×6 and 7×7. Every chart has one solution and can be solved through exact-one deductions without guessing. Arrows see through other arrows, including lit ones.
The clock starts when a chart opens. Your first solve time is saved locally; an uninterrupted, unaided first solve can set the verified best shown on the card and beside the clock.
How to play
- Goal
- Mark the arrows that let every arrow, marked or unmarked, point to exactly one marked arrow.
- How it ends
- A chart is complete when every arrow sees exactly one mark in its pointing direction; there is no loss.
- Record
- Your first solve time is kept per chart, and the fastest verified first solve appears with its holder.
- Every arrow looks from its next square toward the edge in one of eight directions. Exactly one lit arrow must lie along its sightline. Other arrows never block the view, and lit arrows follow the same rule.
- Select Beacon and tap an arrow to light it; tap again to erase. Rule out marks are optional notes, never blockers or targets. Select an arrow to see its ray and current beacon count.
- Undo reverses one painted stroke. Restart clears marks but keeps the clock running. Check reports rule conflicts and makes that attempt local-only. There is no loss; a chart ends when every arrow sees exactly one beacon.

Good to know
Every published chart has one solution, and median deduction effort rises across the three shelves. First-solve records exclude resumed and checked attempts. Progress and reduced motion save; sound follows the shared site setting.
