RTG American Roulette adds the 00 pocket, raising the house edge to 5.26% on all standard bets and 7.89% on the five-number basket (0-00-1-2-3) — the worst wager on the layout.
Why It Persists
The double-zero wheel survives on familiarity for US players raised on land-based layouts. Mathematically it is dominated by the European table available in the same lobby.
If You Play It
Avoid the basket bet unconditionally; every other bet shares the flat 5.26% edge, so bet choice is purely a variance preference.
