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

How this board is solved

Solving this 9x9 board takes 18 deductions and needs the intermediate group-lock techniques, drawing on 6 distinct techniques. It opens by ruling cells out rather than placing a queen. The queens resolve in the order E3 → F1 → A2 → H4 → B5 → I6 → D9 → C7 → G8. Every step follows by logic, so you never have to guess.
