Here is an idea for you if your children are older now. Play them the game for chores instead of money.
That is something I have done with different games and it does make it a little more interesting and fun for everyone.
I have done this with Rummy, Blackjack, Monopoly, Checkers and so on. Just about every game everyone wanted to bet chores on the outcome and it became like a weekly favorite!
It is something to think about.
