Pachi Dice Minigames
Pachi adds Red, Blue, and Green dice bonus games. Upgrades and gacha items increase starting balls, portal behavior, and survival chances.
Red Dice, Blue Dice, and Green Dice each have unlock and entry upgrades. The save file tracks three minigame multipliers, so these are persistent sub-systems rather than throwaway events.
Bubba can throw extra balls into the main board, while Poker Pirate cares about poker hands and unlocks the trips-or-better achievement.
