Spicy Sudoku

Spicy Sudoku is built for players who want beautiful design, serious solving tools, and puzzles worth their time—with no ads, subscriptions, or tracking. The free game includes 200 carefully curated puzzles across ten genuine difficulty levels, from Learner to Fuhgetaboutit. Every puzzle has a detailed Puzzle Dossier and spoiler-protected Solve Narrative. The complete game is fun and fully playable without buying anything. Optional one-time purchases add Method Hints, advanced controls, and extra puzzle packs for players who want to go deeper. PUZZLES CHOSEN FROM MORE THAN A BILLION To build the collection, we analyzed the full solving paths of more than one billion candidate puzzles, then selected the standouts using a ten-dimensional scoring system. Difficulty reflects the logic, structure, and character of the complete solve—not simply the number of clues. Every puzzle has exactly one valid solution and is chosen to provide a clean, fair, logic-driven experience. The result is a collection that feels intentional, varied, and genuinely rewarding. HINTS THAT TEACH—NOT TELL Method Hints identify the logical technique available, then highlight the contributing cells and eliminations without entering the answer. You see why the move works and still get to solve it yourself. Method Hints are included with the optional Advanced Hints one-time purchase. A DOSSIER FOR EVERY PUZZLE Every puzzle has its own personality. Open its Puzzle Dossier to explore its Puzzle Personality, difficulty notes, symmetry, technique profile, and what makes its solving path distinctive. When you want the whole story, reveal the spoiler-protected Detailed Solve Narrative and follow the puzzle from its opening moves to the final deduction. TEN LEVELS THAT ACTUALLY MEAN SOMETHING Most Sudoku apps stop at Easy, Medium, and Hard. Spicy Sudoku uses human-style techniques and full solve-path analysis to classify each puzzle—from singles and pairs through wings, fish, coloring, and chains. That creates room for real progression. Move from Learner, Warm-up, and Coffee Break through Extra Spicy, Dialed Up Past 11, Please Make It Stop, and finally Fuhgetaboutit. Each level has its own character, not just a different clue count. CONTROL WITHOUT CLUTTER Long-press any of the three main controls to reveal its four-way radial menu. Once you know the layouts, simply swipe a control in the desired direction to execute that action instantly. Clean notes and candidate management keep even advanced boards readable. Your progress is protected by unlimited undo, autosave, direct saves, and seamless resume support. A guided tour explains the powerful controls so you can start solving with confidence.
