Let's be honest—most Sudoku games are a pain to play. Manually entering numbers and candidates? Tedious. Accidentally placing the wrong number or eliminating the wrong candidates and ruining your entire puzzle? Frustrating. Getting completely stuck with no idea what technique to use next? Discouraging.
We've solved these exact problems. Our unique cell+skill system means you never have to manually manage candidates or worry about placing wrong numbers again. Just spot a pattern, select a cell, click the technique, and watch as both eliminations and number placements happen automatically. Can't mess it up either—the skill system will never place incorrect numbers or eliminate wrong candidates. If the technique doesn't apply, nothing gets changed.
Stuck and don't know what to do next? Our hint system and comprehensive analysis tool will show you exactly which techniques are available and the analysis tool will explain the logic behind each move. No more staring at the screen wondering if you missed something obvious.
Whether you're a casual player who just wants to solve puzzles without the headaches, or someone looking to master advanced techniques, this game removes the friction and lets you focus on what actually matters—the solving.
Experience Sudoku like never before with our innovative technique-based gameplay, totally unique and don't exist in other Sudoku games or apps. Here's how it works: spot an X-Wing pattern? Simply select any cell from the base regions that contains the candidate, click the "Fish" skill, and boom—the X-Wing is found and eliminations are made automatically! No manual candidate manipulation needed. This is the most efficient way to play Sudoku, letting you focus on pattern recognition while the game handles the tedious work.
