The deep end. Large grids, long runs and minimal freebies. Every cell still falls to logic, but you will earn each one.

How the best solvers approach expert grids
Expert puzzles reward patience and full notation. Mark every candidate, then attack the longest runs with the combination reference, since a long run with an extreme sum still collapses to a single combination. Use the 45 rule on any enclosed block, and keep cross-checking the two runs through each cell. When you are truly stuck, a two-candidate cell tested a few steps forward will usually break the logjam.
A generous hint or two is no shame on this level. If you want to study a finished grid, the solver will complete any puzzle. Prefer a gentler challenge? Step back to hard.
