maybe its nice to have achievements in ludo like gammon and backgammon ?
- win a game of ludo while your opponent has still all its pieces in its base - win a game of ludo while your opponent has still at least a piece in its base - win a game of ludo while your opponent has no pieces in its home yet - win a game of ludo while your opponent has not been on the board at all
and maybe some achievements with a certain number of passes or a certain number of captures, in 1 game or in total, or directly after another (in a row)
