Trudne Sudoku

Trudne Sudoku

Trudne Sudoku is where every placement is earned. These puzzles have fewer givens and longer dry spells, so you rely on elimination patterns instead of constant direct singles. The level is a good fit for solvers who are comfortable with medium grids and want deeper, more methodical logic. Typical solve times sit around 20–45 minutes, depending on how quickly you spot structure. Keep your notes clean, re-check candidates often, and lean on techniques like pointing pairs, redukcja liniowa, and triples. Need to reset fundamentals? Review co zrobić, gdy utkniesz.
