The trick is to not pick the middle. It's the left or right that have the good odds. :wink: There's three boxes, you seriously can't determine chance without examining all three boxes equally. You've done a run of over a hundred, now find that exact number and run the same on the left box, and another hundred+ on the right box. Then you'll be able to get your average.
Anyways, I usually pick the left or right, but I never stick with one box for that long. I think the game is designed for trying to pick the box that has 3 donuts....not just for crossing your fingers and hoping the middle box always has 3 donuts. Play the game right and then we'll talk numbers.
For me, I can get 2 or 3 donuts pretty frequently...as long as I'm "trying". Good luck!
