About Unique Marker
In a lamplit fantasy glazier’s workshop, restore enchanted windows by joining panes into four-cell relics. A pin can sit inside a pane or between two panes.
Explore 160 original charts from 4×4 to 7×7. Every chart has exactly one checked partition; the seam and boundary pin rule matters on every chart.
The clock starts when a chart opens. An uninterrupted first solve can set the best time, shown with its holder beside the clock and on each chart card.
How to play
- Goal
- Divide every open pane into connected four-pane relics, with exactly one counted pin in each.
- How it ends
- A chart is complete when every open pane belongs to one valid relic; there is no loss.
- Record
- Your first solve time is kept per chart; the fastest verified first solve appears with its holder.
- Divide every open pane into connected groups of exactly four. Each group needs exactly one counted dark pin. A pin inside a pane counts for its group. A pin on a seam counts only when both neighboring panes belong to the same group; on a group border it counts for neither. Sealed dark panes stay outside every group. All four-cell shapes may repeat. The worked picture shows an inner seam pin lighting while a border pin remains dark.
- Tap or drag through adjacent open panes to form a relic. The fourth pane seals it when the counted-pin rule holds. Tap a draft pane to remove it; tap a placed relic and use Lift relic to revise it.
- Undo reverses a change. Restart clears the window but keeps its original clock running. A chart ends when every open pane belongs to a valid relic; there is no loss.
