Before you start playing, SWITCH TO TURBO MODE! (Shift click the green flag) The game runs much better in turbo mode. Click the + button to add a player, and the - button to remove one (Min 3 players, Max 7 players!) Click when it says that it is your turn to start.
This took a while (prob about 24 h total work) If you are not sure how to play, search it up. I'm not adding instructions.
