Saturday · 12×12 · Tough · Hard · 25 deductions

12 queens left to place.

Tap once to rule a cell out, twice to place a queen. Right-click marks an exclusion directly. Arrow keys move between cells.

A 12x12 board split into 12 colour regions, needing 12 queens: one per row, one per column, one per region, none touching. Regions run from 4 to 23 cells.

The daily board is the same for everyone and gets harder as the week goes on: Saturday is set to tough. Every daily puzzle has one solution and needs no guessing.

How this board is solved

Solving this 12x12 board takes 25 deductions and needs expert techniques, including testing a queen, drawing on 10 distinct techniques. It opens by ruling cells out rather than placing a queen. The queens resolve in the order C1 → B4 → D7 → K10 → A9 → H8 → E2 → J3 → F12 → I11 → G6 → L5. Every step follows by logic, so you never have to guess.
