A NEW PUZZLE BEHIND EVERY DOOR

Try Equations and find the missing number or operator. Fill a Sudoku grid by pure deduction, from 4x4 up to 9x9, or sweep a Minesweeper board where every clue leads to a safe tile without guessing. Each mode brings its own logic, so this puzzle game never feels repetitive.
