There are three bonus games which you can access through doors that you come across in Feudal Japan and the Goon Docks. Each of the bonus games are described below.

Dice


Choose even or odd to win more missles

In this game, you must guess whether the sum of the roll of two die will be even (chou, チョウ) or odd (han, ハン). If you guess correctly, the number of bullets you possess will be doubled, up to a maximum value of 999. If you guess incorrectly, the number of bullets you possess will be halved.




Cards


Flip over two of the same number to earn life

In this game, you must select two of the five face down cards. The goal is to select two cards that have the same value (e.g. three hearts and three diamonds, as shown in the image to the right). If you succeed, the current character's life will be fully restored. If you fail, your character will suffer damage when you leave the game.
