You're a good coder. You need a full-time designer. But that's not the problem.
Here I go being blunt. The problem is that games like this don't turn big profits. The reason you don't see a lot of board games / multiplayer parimutuel stuff on mainstream casino sites is that they don't tend to be worth the cost of developing and marketing them. That's not to say that mainstream sites aren't blindly stuck in their ways, or that a particular game couldn't go viral. And I think you're going in the right direction, which is to try to spark a sensation, just keep churning 'em out and waiting for one to be a hit. That's basically the same thing we're doing. But the other problem is that a lot of good ideas that could go viral otherwise aren't having the chance right now, because they're hampered by the small size of the Bitcoin gaming market.
I think it would be great to have some really well-designed, parimutuel board games all under one roof, playable for Bitcoin, and separate from casino-land. Games like this are legal in the US, so there's a much bigger market. A site that just ran Bitcoin chess, checkers, go, battleship, connect four, risk, etc., that charged a 1 or 2 BTC/mo. subscription fee plus extras for tournament entries would probably be a big hit.
