How you can use it
To build a turn-based board game, sketch out the rules for legal pieces and spaces. Your developer writes standard code to check the board and list every allowed move. Your app sends this list of choices to TypeSafe, which stops the computer player from making up forbidden moves.
Running the game requires an access key generated from a TypeSafe account to connect the software. If a connection drop occurs or an unexpected reply comes back, the game pauses and asks the player to retry rather than guessing a random move.
