## What is Tessel?

Nine logic puzzles in one calm app, with no ads: Sudoku, Killer Sudoku, Star Battle, Shikaku, Takuzu, Futoshiki, Nonogram, Akari and Hashi. Every puzzle is made on your device, checked to have exactly one solution and graded by the techniques it needs, so the hints teach real reasoning. Tessel works entirely offline, with no account and no tracking.

SUDOKU, DONE PROPERLY
• Five difficulties, from Beginner to Expert, with unlimited puzzles
• A Daily Sudoku, with the last two weeks always open to play
• Pencil notes, undo and redo, and optional auto-notes
• Hints that explain the reasoning in stages, so you learn the technique instead of just being handed the answer
• Your game is saved automatically, so you can leave and pick up exactly where you stopped
• Mistakes are never punished: no lives, no timers you have to watch

MORE PUZZLES TO EXPLORE
Killer Sudoku, Star Battle, Shikaku, Takuzu, Futoshiki, Nonogram, Akari and Hashi, each with its own short walkthrough and hints.

MADE TO BE COMFORTABLE
• Seven themes, each with light and dark looks, including a high-contrast option

• Gentle haptics you can switch off
• Statistics and achievements that stay on your device

PRIVATE BY DESIGN
