Sure I have a random number generator! I have a 7yo and a 6yo.
If it goes into triple digits, I add the dog into the mix. Take 10 pieces of paper numbered 0-9, have each kid pick a number, and put 0 and 1 down on the floor 6 feet apart and tell Murphy to fetch.
Murphy gets the first digit, Mackenzie gets the second and Sophie gets the third, if it's over 100 entries, LOL. If it's under 100, then Murphy just gets to watch. I even have an outside auditor to make sure it's fair, Bailey.
