■ What is 'Minna de Sudoku'?
'Minna de Sudoku' is a web browser game based on the general rules of Sudoku, allowing real-time battles with online players. No app installation is required; simply access it from your PC or smartphone browser to start playing immediately.

■ Main Game Features
1. 'Real-Time Territory Capture Battle' to Compete for a Single Board
In battles, you use the exact same board as your opponent and fill in numbers simultaneously. Squares where the opponent has already entered the correct answer become unavailable for you to input. Therefore, the key to victory lies in how quickly and accurately you can decipher the board.

2. Accurate and Speedy Answers are Key
Correct answers earn points equal to the number entered (e.g., 9 points for entering '9'). However, incorrect answers result in a deduction of 'number of mistakes × entered number', and a score below -100 leads to an immediate 'forfeit'. Rushing to input uncertain numbers is highly risky; a delicate balance between 'accuracy' in reliably deciphering the board and 'speed' to capture squares before the opponent is tested.
3. 'Rating & Monthly Rankings' to Prove Your Skill
The game employs a rating system that increases or decreases based on battle results. Ranks range from 'Iron' to the highest, 'Immortal', reflecting player skill. You can aim for the top in the 'Monthly Rankings', competing with players nationwide, allowing for highly competitive play.

4. Rich Content and Customization Features
In addition to 'CPU battles (adjustable difficulty)' for when you don't have an opponent or want to practice, the game includes features to record player achievements and settings to customize themes (dark/light), font sizes, and more. It provides a stress-free playing environment.
