Merton Council publishes a register of gambling premises in the borough.
It lists betting shops and two adult amusement arcades, and no casino.
For a south west Londoner who wants a game of roulette, that leaves three realistic routes.
A trip into the West End
For a live table, the usual answer is a trip into central London.
The Hippodrome in Leicester Square says on its roulette page that its wheels run from 0 to 36 and that it also offers Las Vegas-style “00” wheels.
It states that if 0 wins, half of all even-chance bets are returned, and it describes more than 100 electronic roulette, blackjack and baccarat terminals with minimum bets from 20p to £50 per chip.
A visit means choosing between live tables and terminals, and between wheels that do not play the same.
Online, if the operator is licensed
The second route is a licensed online operator, which removes the journey but not the question about the wheel.
A single zero means a European or French layout, and a 0 and a 00 means American.
That extra pocket roughly doubles the house edge, from 2.70 per cent to 5.26 per cent, and £10 on red costs about 27p per spin on average on the single-zero wheel against about 53p on the double-zero one.
French tables with La Partage return half of an even-money stake on zero, which brings the cost down to about 13.5p.
Readers who want to compare the versions across UK-licensed operators can use a review of roulette sites at Online-Casinos.com, which ranks them and sets the odds for each version side by side.
What the high street offers
The third route is the one local people already know.
Our 2019 report on bookies and casinos dying out in our area described roulette-style terminals in bookmakers, including in Wimbledon, and the cut in the maximum stake on fixed-odds betting terminals to £2 from 1 April 2019.
These are electronic games, so the wheel rules in a casino do not apply in the same way, and the posted terms on the machine are the thing to read.
How to check any table or machine
Look for the rules panel and the words La Partage or En Prison.
A table called French does not always carry either rule, so the posted rules are the only reliable guide, and in a building with several wheels they can change from table to table.
Keep it a night out
Roulette is entertainment, so the sensible budget is the amount you are happy to spend on the evening.
Set the limit before you play and stop when it is gone.
Whichever route you take, confirm that the operator holds a Gambling Commission licence on the Commission’s public register.
