Unlocking characters:
     To   unlock   the  grayed-out  characters,  complete  a  game  of
Tamagotchi  Party  On!.  For example, if you choose a 3-election game,
you  will  not get a character for each election you complete, however
you will for completing the entire 3-election game itself. If you want
to unlock characters faster, just keep playing 1-election games.

     To unlock the last three secret characters, go to the "Challenge"
option  on  the main menu. Get gold medals on all the "Mini-games" and
"Gotchi Games". You will now have the last three characters to play as
in all modes: Purimatchi, Matsuritchi, and Shitiketchi.

Letting the computer roll:
     Do  not  press  A  to  skip the CPU's roll. If you do, instead of
relying on the die's bounces to choose the amount of spaces they move,
it  will  be  a  random number and could result in giving the CPU more
spaces to move than they would have had before.
