Welcome to Sudoku Vault, the ultimate brain workout that’s like CrossFit for your neurons! We've got puzzle sizes that range from “Oh look, a tiny grid!” (4x4) to “I need a bigger coffee!” (9x9). Choose your adventure from four levels of difficulty: Basic (for when you're feeling casual), Normal (for the mildly ambitious), Hard (for when you want to challenge your sanity), and Expert (for those who think they can outsmart a calculator).
Worried about losing track of your genius ideas? Fear not! Our smart NOTES are here to save the day, like a superhero for your thoughts! And when you’re ready to see how well you’re doing (or how many brain cells you’ve lost), just tap the magical CHECK button. It’ll whisk away your wrong guesses faster than you can say “Oops!” and keep the right ones locked in like a toddler with a cookie jar. So grab your pencil, put on your thinking cap, and let’s see if you can conquer the Sudoku puzzle world without losing your marbles!
Use a mouse or touchpad to select a cell, then choose a number from the on-screen number pad to fill it in. Use the Note button to toggle pencil marks, and tap Check to validate your entries — incorrect numbers are removed, and correct ones are locked.
