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.
