How a game opens
Your server creates a session token for the player.

Open the game in an iframe (recommended). The PG Soft launch script avoids pop-up blockers.
PG Soft checks the token with your server. New players are created automatically.
In seamless mode every bet and payout then goes through your wallet calls.
