Cheat Mode:

Note that this requires the four-player adapter for the Famicom. It also requires at least one controller that can press Up and Down on the D-Pad simultaneously. On the opponent's turn, hold Up, Down, and B on Controller 3 for a few seconds, then release the buttons. A menu with two options will appear: the first allows you to see the opponent's tiles, and the second engages an autoplay mode where everyone is AI-controlled.

 

Extra Points and Tickets:

Note that this requires the use of the Famicom's four-player adapter and a controller that can press opposing D-Pad buttons simultaneously. In the main game mode, when asked to buy tickets, select "Yes", then press A. Immediately after, hold Up, Down, and B on Controller 3. When the shopkeep returns, you should earn 300,00 points and 270 tickets, and then can play the final round against the most skilled players.
