roulette glossary

Roulette has a long history and has been the subject of many myths and legends, so it’s no surprise that there are a lot of roulette terms, jargon and slang associated with the game.

If you take a look at the site, you’ll soon get to grips with it, but if you need a quick introduction to the more common jargon that you’ll come across, then have a read through our glossary of roulette slang terms.


Learn the Roulette Terms & Lingo

If you feel a bit intimidated playing on a roulette wheel in a casino, start off on the lower denomination chip tables. The chances are that less people will be expert players as people will be there for a flutter. Start off with an easy bet like red/black and then just observe what is going on – you’ll soon get used to it. Another good tip is to start off playing online on a live table (say Dragonara Roulette which is a Dual table, online and offline). You can get comfortable with the different bets from home.
