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 14 deductions and needs the intermediate group-lock techniques, drawing on 6 distinct techniques. The first queen you can place for certain is D1. The queens resolve in the order D1 → A5 → H10 → B2 → I3 → C6 → E4 → F9 → G7 → J8. Every step follows by logic, so you never have to guess.
