Why play medium 15x15?

At 225 cells, the 15×15 demands method: mark the forbidden cells, revisit every line after each find, let the columns confirm the rows. Plan for 20 to 40 minutes depending on density.

On medium, you’ll alternate between rows and columns more often: deductions come in small touches, and ✕ marks become as precious as filled cells.

This page’s grid has 132 filled cells out of 225 (59%) and resolves in 5 propagation passes — verified solvable without ever guessing, like all our grids.
