MarsSeed [1] filed a deletion request for sudoku-git [2]: I don't think anyone uses this EOL software from 2012. 0 pkgstats. This game app also generates unreliable, improper sudoku puzzles that have too many different solutions. (A normal sudoku should have exactly one solution.) This problem also sometimes leads to puzzles that cannot be solved without cheating (asking the software for solution hints). There are several alternatives for GUI based sudoku games with a proper puzzle generation algorithm. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/sudoku-git/
