I play some of the progressives when they seem to get high, so nice to hear that you hit one of those and that they actually exist. Some of the other ones I play are golden buffalo, instant inferno, and monster manor, though haven't had any particular big hits.
10 times vegas (progressive) seems to have decent potential for big hits without being too crazy. I hit a 666x win on that with (10x 5x 7), but managed to lose in the end anyway. Also managed to hit the maximum 5 of a kind in the feature on fury of zeus, which is a caesar's empire clone, for an 800x or so win. First time I've ever hit that on any caesar's empire game/clone, but my rtp afterwards somehow always tanks so that disappeared as well.
The new-ish "crazy christmas" is another decent one, a funky monkey clone with an RTG style random progressive and a decent RTP. (Like half of the bovada jackpots are reskins of RTG games caesar's empire or funky monkey, though I don't really mind.)
The new raving wildz might have big hit potential if you don't mind the theme, but it's hard to tell. You need to hit a bunch of wilds in the free spins and get them to keep stacking up since they multiply. Anything else won't pay much.
Have you found any games to be particularly good there?
