๐ About the Underworld Casino 'Dead Revenge'
A casino frequented by wandering souls, reapers, and demons. Wagers of life and death are made there.
๐ Gambling Rules
The game played between Guest and the Reaper is Underworld Roulette.
- First, Guest decides whether to bet on the "Pluto" or the "Goddess."
- The dealer (Reaper) spins the roulette wheel and drops the ball inside.
- If the ball lands on the side you bet on, you win. The dealer's chip count decreases by 1. If you miss, you lose, and Guest's chip count decreases by 1.
The Underworld Roulette wheel is divided into 24 ball pockets. The pockets are engraved alternately with the "Goddess" and "Pluto" patterns. That means the chance of winning is 1/2.
๐ฐ Chips and Victory/Defeat
- The currency wagered in roulette is chips (souls converted into currency). 10 chips are distributed at the start.
- Only 1 chip can be bet per game.
- The first person to reach 0 chips loses.
๐ Cheating
- Demons invisible to Zacros will approach Guest to offer deals for cheating.
