When playing online Roulette, players can choose their coin size according to the budget that they have set themselves. It is not advised to place a large bet to start with but rather small bets and increase the value of each bet as confidence in the game grows. In fact the Martingdale theory suggests that for every losing bet a greater value bet should be placed in the belief that eventually all of the losses will be won back. This is a great theory to follow if players have enough money to cover all of the bets needed but otherwise it is just as good to start with low value bets. Players can also try out the game for fun or practice before they place real money bets which introduces them to the game and allows them the opportunity to get to know the game and how it works.
