P2P2KESTREL

P2P2KESTREL is a vertical Sudoku logic puzzle mobile game. The standard 9x9 board is divided into nine 3x3 boxes. Players first tap an empty cell, then use the number keys below to fill in numbers from 1 to 9, ensuring that numbers do not repeat in each row, each column, or each box. Each correct entry earns points, while too many mistakes cause the round to fail. The number of blank cells and the difficulty increase as the game progresses, requiring players to combine unique candidates, elimination, and cross-box reasoning to gradually narrow down the answers. The interface provides pause, restart, and return to main menu, and saves the all-time high score. The game does not rely on reaction speed but emphasizes patient observation and logical chains, making it suitable for Sudoku enthusiasts who enjoy quiet thinking and completing a full board of reasoning, as well as for daily mental warm-ups.
