The game master selects players to play with from the Contacts and KakaoTalk friends, and enters a topic. Then a fake artist is randomly selected among the selected players. When you push 'Send' button, the topic and the identity are automatically delivered to each player via SMS or KakaoTalk message.
The game master don't need to prepare the tile cards as many as the number of players one by one. Basically the game is designed for 5 to 11 players, but you can play without a limit of number of players as long as you have a piece of paper to draw on and color pens as many as the number of players.
