Meta Sudoku

Meta Sudoku is a minimalist Sudoku puzzle game. You fill a 9 × 9 grid with the numbers 1 through 9 so that each row, column and 3 × 3 box contains every number exactly once, following the numbers already given. It has four modes with different level sets and difficulty progressions.

Game modes

• Classic Mode: Six difficulty levels—easy, medium, advanced, difficult, expert and master—with 40 levels in each.
• Pack mode: Three levels of difficulty, Pack I., Pack II. and Pack III., with 25 levels in each. The puzzles have geometric arrangements of the given numbers.
• Endless mode: Six difficulty levels—easy, medium, advanced, difficult, expert and master. Each time you enter a new level, the game selects one suited to you.
• Ultimate Mode: Three levels designed by world-class masters, intended as a test for players familiar with the game mechanics.

Puzzle tools and settings

The game has multiple color themes, quiet ambient music and mechanisms designed to reduce optical illusions. You can undo and redo moves, use hints to see the remaining numbers, and use shortcut keys. Leaving a puzzle partway through saves your time and progress; this can be changed in the settings.
