Sudylko
A calm, keyboard-first Sudoku for the Mac, with seeded puzzles, notes, achievements and a timer in the Dock.
A macOS build isn't published yet. Check back after the next release.

Seeded puzzles
Every puzzle comes from a number and a difficulty, like #1384 on Medium, so you can replay one or send it to a friend.
Play from the keyboard
Type digits, undo, and move around the board without reaching for the mouse. Press ⇧? to see the shortcuts.
Stats and achievements
Your saves, lifetime stats and achievements live in the sidebar, and the Dock icon takes your accent color and shows your timer while you play.
