Sudoku Pulse — Learns how you think. This isn't just another Sudoku app. Sudoku Pulse comes with a personal AI coach that adapts to your skill level, teaches you real solving techniques, and challenges you to keep improving. YOUR PERSONAL AI COACH After each puzzle, your AI coach shares insights about your game — what went well, where you can improve, and what technique to try next. It's not generic tips — it's specific to how you just played. The more you play, the smarter it gets. It learns whether you prefer solving by boxes, rows, or numbers — and tailors your experience accordingly. AI CHALLENGES Your coach doesn't just help — it dares you. Each challenge is crafted for your skill level. Beat a target time. Solve without mistakes. Push past your comfort zone. Don't like the dare? Refresh for a new one. Beat it? The next one gets harder. HINTS THAT ACTUALLY TEACH Every other Sudoku app reveals the answer. We explain WHY. Tap a hint and see: "This row has 8 numbers filled — only one is missing." You learn real solving techniques — naturally, while playing. A "Learn" button walks you through each technique step by step, right on your puzzle. DIFFICULTY THAT GROWS WITH YOU No need to choose Easy, Medium, or Hard. Sudoku Pulse adjusts puzzle difficulty based on how you play. Each puzzle sits right at the edge of your ability — challenging enough to grow, never frustrating enough to quit. STUCK? FREE HELP. If you haven't made a move in a while, the AI offers a free nudge. Not a hint — a direction. "Try the bottom-right box" or "Look at the 7s." It points you the right way without solving it for you. No hints consumed. INSIGHTS THAT MATTER Your stats page isn't a spreadsheet. It shows your strengths, focus areas, and a personalised summary that evolves as you improve. See what you're great at. See where to grow next. DAILY CHALLENGES A new puzzle every day. Build your streak. Each challenge matches your current skill level — always the right amount of challenge.
