  1. Warm up on Easy

    Practice naked singles and hidden singles until they feel automatic. They speed up every puzzle - no matter the difficulty.

  3. Embrace Hard patterns

    Learn X-Wing variations and simple coloring so you can dismantle the toughest eliminations in Hard grids.

  4. Upgrade to Expert tactics

    Finned fish and uniqueness techniques give you the firepower to crack Expert puzzles without guessing.

    Combine ALS, forcing chains, Sue de Coq, and Kraken Fish for the rarest solving situations.
