Doble Duck
Introduction
On January 9, 2024, I came across the Doble Duck side bet at Casino Life in Mexico City. This bet wins when either the Player or Banker achieves a three-card hand of three sixes. Here’s the payout structure:
- If both Player and Banker achieve 6-6-6 — Payout is 100 to 1.
- If either the Player or Banker has 6-6-6 — Payout is 8 to 1.

The bottom right corner indicates a house edge of 99.39%. That's likely the highest house edge I've encountered on any side bet.
