Should probably make the games visible to the public even if they do not currently have an account. As someone suggested maybe have some sort of temporary account with a login url, so that people are able to use that instead of signing up. Gamblers are quite impatient.

Also, how about zero confirmation deposits? THat would be a nice feature to have as well.

But overall, great site. I love the snake game... The rewards are a bit on the low side, though.
