Today's card shows the board with its numbers and given tags only, your time band, streak and the days to launch; a card for an earlier day shows that day's strikes. Never today's answer.

Strike out repeated badge tags so that no number is left twice in any row or column, struck tags never touch side by side, and every standing tag stays in one group. 8×8 on weekdays, the 10×10 full precinct at the weekend, a 6×6 warm-up, brushes and drag-paint, live rule checks, one hint, a streak, personal bests and a spoiler-free result to share. A fan puzzle about an imagined precinct, never real policing.

How to play

The board is a grid of numbered badge tags. Strike out tags so that no number is left twice in any row or column among the standing tags, struck tags never touch side by side, and every standing tag stays in one connected group. Tap a tag to cycle it, or pick a brush and drag; a repeated number still standing glows amber, a tag that breaks a rule outright turns red, and the checks only ever look at the rules, never at the answer. Undo and Clear all are there when a line goes wrong. Every board is checked when the site is built by a solver that runs the same rules you use (a kept tag strikes its copies, a struck tag keeps its neighbours, the sandwich and the pair, the cut) and then tries both ways on any tag the rules leave open, so each has exactly one answer and opens with at least one tag the rules force; the 6×6 warm-ups fall to the rules alone, with no guessing at all.

Tip one: a tag sitting between two copies of itself must stay. If a row reads 4, 7, 4, the 7 cannot go: striking it would leave both 4s standing in the same row, so circle the 7, and every other 7 in its row and column is struck at once. Tip two: two equal numbers side by side cannot both go. Struck tags never touch, so one of a pair like 5, 5 stays, and every other 5 in that line is struck; then look at what those strikes keep standing, because every tag next to a struck one stays, and a tag whose striking would box in a corner or split the board has to stay too.

Everyone gets the same board on the same UTC day: 8×8 on weekdays, the 10×10 full precinct at the weekend, and newcomers can switch on the 6×6 warm-up, which still counts. One hint a day marks one tag the rules force, says which rule, and marks the result as assisted. When the last repeat is struck the board settles, the case stamp comes down and the desk sergeant signs off with your time; Give up shows the board and ends the day without a clear. The archive lets you play any earlier day's board and practice boards come from a spare pool; both are marked and never count. Lineup is a fan puzzle about an imagined precinct lineup board: the numbers are abstract tags, never real badge numbers, nothing here is an insignia or a procedure, nothing comes from a leak, and nothing is presented as official. For more deduction try the Dragnet, the Stakeout and the Patrol Grid.

Questions

What are the rules?

The board is a grid of numbered badge tags. Strike out tags so that no number is left twice in any row or column among the tags still standing; struck tags never touch side by side (corner to corner is fine); and every standing tag stays in one connected group, joined side to side. A few tags may be given from the start. Every board here has exactly one answer.

How do I mark a tag?

Tap a tag to cycle it: open, struck, circled (marked as staying), open. Or pick a brush (Strike or Keep) and every tap paints that; drag across tags to paint a run; tap the brush again to go back to cycling. On a keyboard the arrows move the cursor, Space strikes a tag (again to open it), Backspace circles it (again to open it), Delete opens, Enter checks, U undoes. Undo takes back the last change and Clear all empties the board (the given tags stay). No soft keyboard ever opens.

What do the highlights mean?

Two standing tags with the same number in a row or column glow amber until one goes. A tag turns red when it breaks a rule outright: two struck tags touching side by side, two circled copies of a number in one line, or a standing tag cut off from the main group. The checks only ever look at the rules, never at the answer. One hint a day marks one tag the named rules force, says which rule, and marks the result as assisted. Give up shows the board and ends the day without a clear.

What is the warm-up?

A 6×6 board for newcomers, switched on with the Warm-up toggle (remembered on this device). Every warm-up falls to the named rules alone, with no guessing. It counts as the day's solve; the 8×8 weekday and 10×10 weekend boards are what the best times are about.

Is this real policing?

No. Lineup is a fan logic puzzle about an imagined precinct lineup board. The numbers are abstract tags, never real badge numbers; nothing here is an insignia, a procedure, a person or an asset from the game; nothing comes from a leak, and nothing is presented as official.

Getaway
