Sudoku

I love Sudoku. I played many different apps throughout the years and all of them lacked one feature or another so I decided to build my own.

Whit this I can add pencil marks, set cell background colours, undo unlimited moves and bookmark games to play again.

Features

6 Difficulty levels even though I only play the hardest one
Pencil marks alongside regular values, with erase and undo
Number lock: pick a number once, then write or remove it across squares by tapping or dragging
Colours: choose a colour and paint squares to flag actions
Highlighting of the selected number and conflicts
Mistake limit, counted against the puzzle’s answer or only against conflicts
Bookmarks to replay saved puzzles again
