roulette straight up bet

When a zero turns up, the player has two options: Reclaim half the bet and lose the other half. Leave the bet (en prison = in prison) for the next spin of the roulette wheel for an all or nothing gamble. If the subsequent spin is again zero, or does not match the imprisoned bet, then the whole bet is lost.

Zero is neither red nor black, high (passe) nor low (manque) in roulette, nor is it counted as either even or odd. Mathematically, zero is even, but if roulette treated it as such, then pair would be marginally an odds-on bet paying off at even money, which would be a loss to the house.

The best roulette strategy requires you to change the size of the bet based on your results. For example, when using the Martingale strategy, you have to double the bet after a loss and then reset to the initial bet after you win.

Progressive betting in roulette\n\n They often involve following a betting pattern  some of the most famous strategies that follow this are the likes of the Martingale, D'Alembert, Fibonacci, and Labouchere. One word of warning  progressive strategies involve a certain level of risk and often a high bankroll.
