sudoku.studio vs Pupini

Studio Sudoku combines clean minimalist visuals with robust logic tools across three 9×9 variants: Classic (standard 3×3 boxes), Diagonal (both main diagonals must stay unique), and Killer (irregular cages must add up to fixed sums). Choose easy, medium, or hard difficulty, switch between digits or pencil marks either via a dedicated toggle or by holding a cell, and rely on the highlight-equals option to instantly show every matching number. Hints are limited, mistakes penalize your score, and the progress bar shrinks as time elapses or errors pile up—so you always know how much is left. Settings let you pick the interface language, force dark/light mode or follow the system theme, and toggle tactile feedback for notes. Detailed statistics capture wins, losses, streaks, and variant breakdowns while the goals board tracks milestones like diagonal mastery or Killer victories. With animated gradients, contextual dialogs, and adaptive layouts, Studio Sudoku keeps advanced solving satisfying without sacrificing polish.
