10 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 10x10 board split into 10 colour regions, needing 10 queens: one per row, one per column, one per region, none touching. Regions run from 2 to 30 cells.

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

How this board is solved

Solving this 10x10 board takes 19 deductions and needs the intermediate group-lock techniques, drawing on 5 distinct techniques. It opens on row 2, ruling cells out before any queen goes down. The queens resolve in the order B2 → H10 → F8 → G6 → J7 → C5 → I1 → A4 → D9 → E3. Every step follows by logic, so you never have to guess.
