Cho-Han
Quick Pitch
Cho-Han is a traditional Japanese dice game where the dealer shakes two dice under a cup and players bet on whether the total will be odd (Han) or even (Cho).
Hook
Two dice rattle under a cup. The dealer lifts it just a crack, peeks, and sets it back down. Everyone around the table places their bet — Cho or Han, even or odd. Then the cup comes up. Cho-Han is one of the simplest gambling games ever devised, perfectly fair (exactly 50-50), and loaded with atmosphere. No wonder it appears in nearly every samurai film ever made.

Tips
- Mathematical balance: Exactly 50-50 probability for even and odd—no advantage to either bet
- Personal bias: Some players favor one over the other (superstition)
- Streaks: Watch for perception of streaks, though each roll is independent
- Bankroll management: Bet conservatively to avoid early elimination
- Dealer advantage: In house variant, the dealer makes small profit over time
- No true strategy: With equal probability, betting strategy doesn't matter mathematically
Variations

- Gives the house/dealer long-term advantage
Side Bets

- Changes house odds
Three-dice Version
- Uses three dice instead of two
- Different probability distribution
Multiple Rounds
- Play fixed number of rounds (e.g., 10)
- Player with most chips at end wins
