This brings back memories! Some great MG slots in the Viper client back in the day, I was a big fan of Gypsy Queen which was exclusive to the download casino and very hard to find.
Ontario residents can play them at BetRivers. China Shores gets a ton of action from me. Last month I had two jackpots betting 30 cents. Probably their most popular slot.Konami. Brought some fantastic land based games online to a handful of obscure casinos then just seemed to fade away I still wonder wtf happened there.
You'd need to check out older IGT (as already stated) and MG, the Cryptologic and Incredible Technologies ones have gone. Bally ones like Quick Hit series are still out there (under the SG/Shite & Blunder banner now) and I believe some of the old Ash Gaming classics are still offered in casinos with Playtake slots. I can name many old slot developers but cannot state with any certainty if their games are still about under their original banners or whomever took them over.
These are most of the old developers if any games from them ring any bells:
I'm pretty sure these have all been online, still are AFAIK:
Choy Sun Doa
Lets Go Fishn
Queen Of The Nile
Queen Of The Nile 2
Sun And Moon
Wheres The Gold
Pretty sure they were at Videoslots once upon a time.Would be keen to know which online casino any of these are available on. I’ve had ROMs of some of these games (played in an emulator) but have never seen real money versions outside of NZ/Australian/US land based casinos.
