The numbers behind the table
European single-zero roulette returns about 97.3%; the American double-zero version drops that to roughly 94.7%. The table you pick matters more than anything you do at it.
What to watch for
Side bets on live tables carry a materially worse edge than the main bets - that is where the studio makes its margin.
Live tables run in the browser on mobile too - see the app page. Bonus contribution rules are on the welcome bonus page.
