I don't recommend anyone getting this shit. If you check out the live demo and open any slot, you can clearly see that he's providing cracked slots. That's why not all games are available. Open any game and check the iframe URL, it's some weird ass shit that is definitely not from the real providers, which could get you into legal trouble with them. Also, the RTP is often much lower, and you can probably find similar scripts for free on some forums.
