something harder now I guess, finally I found this game I played long, long time ago!

there are mother, father, 2 children, policeman and thief;
and the rules are:
- father can't be with their daughters on the one side without mother;
- mother can't be with their sons on the one side without father;
- thief can't stay with any of family member without policeman;
ah, and remember that children can't control the batch
good luck! xD
