Total wagers vs. total payouts

Those look like my Roxy stats

The payouts aren’t actual payouts like they withdrew the money in this case, it represents the amount returned on the total wagers. So I bet 10 and get 8 back on the spin or whatever, I have wagered 10 and the payout was 8. I lost 2 overall.

In your example, it looks like your players have lost 300, so you should be owed commission on the 300.
