Hello,
firstly we are mainly a development company with focus and experience in security and namely cryptocurrencies, most notably Bitcoin of course. We have developed complex and highly secured Bitcoin exchange solutions and payment processing systems, and also contributed to various casino games (Blackjack, BTC Wheel...).
As for the project, there are several things that should be further specified; firstly in regards to the "spin and 3 win" system, how would that be done, 3 separate spins or something else? Also would the spins have to be somehow initiated manually? (by admin, who gets notified when the all 10 users signed up for instance)
There is also the issue of concurrency of users (especially at the beginning, there might not be all 10 users signing up for a game instantly, so some of the users would have to wait for others to join and spin), so I think it would make more sense if admin had the ability to create multiple games with multiple options (i.e. different minimal deposits etc.) which would be time limited, and the spin would happen only if all the people came, otherwise, people would get their bitcoin back... Conversely if enough people joined, they would be notified that in x minutes, the spin will happen.
I have a lot more notes, but not enough space here, so let me know if you want to have a chat about the project further (we should discuss which technologies you'd like to be used etc.)
Kind regards
