NUMERICAL ALCHEMIST

A 9x9 Sudoku-based logic puzzle with eight original constraints. Every stage is solved through pure logic alone, with no assumptions or brute force. The thrill comes when one breakthrough makes the board suddenly unravel. Even seasoned Sudoku players will find fresh discoveries and real challenge.
