Open this game on mobile and connect to the host on a computer. All connections to the host will be counted as players that can enter a name and build an avatar. 

The games available to play are JustOne and CodenamesAlliance (a game based on CodenamesDuet). I do not have rights to either of these games and have only used them as practice and to demonstrate development capability.
