## What is Futoshiki Mastermind?

Dive into Futoshiki, the Japanese logic puzzle where every grid hides a unique challenge. Fill the squares with numbers while following the rules of uniqueness, and pay attention to the greater and smaller signs that show the relation between two adjacent cells. There is only one possible solution – can you find it?

Futoshiki offers several ways to play. Progress through levels of increasing difficulty, take on the daily challenge with a brand-new puzzle every day, or enjoy the infinite mode with automatically generated grids.

Track your progress with integrated trophies and statistics. Save your games with iCloud and pick them up again on any of your devices.

The game is free with light advertising. A single purchase removes the ads and unlocks the Hard and Extreme levels. The purchase is universal (iPhone and iPad) and supports Family Sharing.

Futoshiki is available in more than 20 languages, including French, English, Spanish, Italian, German, Portuguese (Brazil), Japanese, and Korean.

It’s the perfect app for fans of Sudoku, Binairo and other logic puzzles. Will you master the inequalities?
