It’s definitely an inexact science, but I generally won’t play for a mini anyway in the unnumbered version.
If it were part of a combo, that’s one thing, but solo-chasing just a mini—which will pay, what, like 15x the bet or so—is not something I’d endorse unless it’s just a few spots away. I have 121/125 on the regular version, and even that might be a little loose considering how poorly it often pays.
Now, had your photo been a mega, I’d have been in. Same with a grand. The major would be a little leery, as it’s not right at the top from what I can tell, but gun to my head, I might gamble on that as well. But I would not go for a mini or minor, assuming the other colors were far away.
