Roullete is a game that’s played in casinos and other gambling dens all over the world. It was invented in the late 1700s and is now one of the most popular casino games online and offline. There are three main variations of the game, American, European and French, with each having subtle differences that every player should be aware of.

Roulette consists of a spinning wheel with thirty-six divisions numbered from 1 to 36. The divisions are painted alternately red and black, with a single green compartment labelled ‘0’ on European-style wheels. On American tables, the extra green compartment is labelled ’00’. A ball is dropped into the wheel and if it lands in any of the numbers you’ve staked on, you win.

Players place their bets by placing chips on a betting mat. Each chip represents a different bet type. Bets on individual numbers are called ‘Inside bets’, while those on groups of six or more are called ‘Outside bets’.

There are various ways to bet on the outcome of a spin, and countless systems for beating the house edge. A simple search on Google will return hundreds of (possibly millions) of systems, some well explained, some not so much.

The symmetry of the European roulette wheel makes for interesting betting opportunities. For instance, the low red numbers and high black numbers are on the same side of the zero, while all the other number groups are separated by the 0 from each other. This means you can make a ‘Dozen’ bet, where you bet that the ball will land in the first, second or third ’12’ squares. This bet pays out at 2-1 and has a very low house edge.
