Sudoku Twist is built for players who want to understand Sudoku, not just finish grids. Guided lessons take you from basic rules to candidate flow, scanning, locked candidates, and advanced patterns — with strategy articles that explain why techniques work, and a Smart Coach that nudges you toward the next logical move without solving it for you. Explore 12+ modes: Classic, 6×6, 12×12, 16×16, Samurai Multidoku, Fog Reveal, Killer, Diagonal, Thermo, Arrow, Kropki, and Vanilla. And more.
