Sudoku Challenger: Puzzle Game

Sudoku Challenger is a classic 9x9 Sudoku puzzle game with a competitive twist: your results shape an ELO rating and your progress through a rank ladder. Solve number puzzles at your own pace, use helpful tools when you need them, and see how your logic skills grow over time. FIVE SUDOKU DIFFICULTY LEVELS Choose from Easy, Medium, Hard, Extreme and Grandmaster. Easy and Medium give you a place to start. Hard and above become available as you progress: win three puzzles in the previous tier or reach the required ELO rank. Each level has a different clue range and a target solve time, so you can choose the challenge that fits your day. The difficulty sheet shows which levels are open and what you need to unlock the next one. CLASSIC NUMBER PUZZLES, USEFUL TOOLS Fill a 9x9 grid using logic. Select a square, enter a number, erase a move or add pencil notes while you work through possibilities. A timer helps you follow your pace. Hints can reveal a step when you are stuck. The board highlights your selection and gives feedback on incorrect entries. If you need a break, pause your game and return to an unfinished puzzle later. ELO RATING AND RANK PROGRESSION Sudoku Challenger gives every result meaning. Wins and losses affect your ELO rating, and the home screen shows your current rank, rating and progress toward the next milestone. As you improve, work through the ranks from Novice toward Grandmaster. Try a harder Sudoku puzzle to test your reasoning, or revisit an easier level to build consistency. Your profile includes an ELO history chart so you can see your progress across games. STATS THAT SHOW HOW YOU ARE IMPROVING Check your games played, wins, win rate, average and best solve times, current and best streaks, and performance at each difficulty level. The Stats screen groups results by difficulty. Your Profile shows recent games alongside your rank and rating. These details make it easy to set a personal goal, whether that means solving more puzzles, improving your time or reaching the next rank. HINTS, LIVES AND SECOND CHANCES Free players begin each game with three lives and receive ten free hints per day. A wrong placement can cost a life. If you run out, an optional rewarded ad can give you another chance to continue the puzzle. After your daily free hints are used, a rewarded ad can provide an extra hint. You can ignore these options and simply play your next Sudoku game. Your current hint count and game controls are visible on the board. PLAY YOUR WAY Choose light, dark or system theme. Turn sound effects and vibration on or off. Set an optional daily reminder at a time you choose; reminders are off by default. The layout adapts to different Android screen sizes, and the controls include accessibility labels. A quick opening skill check helps set an initial rating, and you can skip it if you prefer to start playing right away. OPTIONAL PREMIUM Sudoku Challenger is free to install and play. A Premium subscription removes ads, starts each puzzle with six lives and lets you enable unlimited hints in Settings. Subscription price and terms are shown by Google Play before purchase, and you can manage or cancel the subscription through Google Play. Premium is optional; the classic Sudoku board, difficulty progression, ELO ranking and stats are available in free play. WHY PLAY SUDOKU CHALLENGER?
