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 1 to 31 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.
