so a 1.00 straight bet at betslips on straight +box would get you 1800.00 correct?
If you bet $1 straight and $1 box, yes.
With the other online that we used to use, I had a couple of hits like that. I would have a set of maybe 20 numbers that I was betting in a particular state/draw and I would check the "box" bet. Sometimes one of those numbers happened to be a triple. I hit the triple twice that I can remember and was paid for the straight payout.
A triple has ONE unique digit and would pay 900:1.
