Casino de Monte-Carlo

The building that made the single zero famous and the stories that made the building famous.

Short answer

Opened in 1863 and rebuilt by Charles Garnier in 1878, the Casino de Monte-Carlo is the model for every casino resort since. Its roulette tables run single-zero wheels with French rules and have produced the game’s best-known anecdotes.

The building

The first casino was a modest villa. In 1878 Charles Garnier, fresh from the Paris Opéra, added the Salle Garnier and the façade that appears in every photograph: two towers, a terrace facing the sea, and a gaming floor of gilded salons designed to make a player feel that losing here was a kind of belonging. The Salle Europe, with its stained glass and eight chandeliers, has held roulette tables since it opened and still does.

En PrisonLa Partage

The arithmetic that built a state

At 2.70% on most bets and 1.35% on even money, the edge was lower than any competitor’s. Volume made up for it: trains from Nice from 1868, hotels on the hill, a season that ran all winter. By 1869 the casino paid for the state and income tax was abolished.

Visiting

The main salons admit visitors over 18 with ID; locals are still barred from gambling. There is an entrance fee for the gaming rooms and a free area with slot machines.

Questions

Can anyone play?

Visitors over 18 with ID, dressed appropriately. Monégasque citizens may not gamble.

Are the odds better than elsewhere?

Single zero with French rules is the best standard roulette anywhere; many European casinos match it.

Is the 1913 run commemorated?

Not officially. The casino has never confirmed the table or the date beyond the accepted account.

Comic relief

Low edge, high volume, a railway and a very good architect.
