Roulette 666 Strategy Explained: What Is The 666 Betting System?

Roulette has several strategies players use to help them structure their bets. One of these strategies is the 666 strategy.

With a name that typically raises eyebrows or sparks debates, does this strategy work, and is it allowed in the casino? Find out here in this Clover Casino blog post. 

What Is The 666 Roulette Strategy?

The 666 roulette strategy is a betting system that covers almost all the numbers on a roulette wheel. It is called the 666 betting strategy because the numbers 1 to 36 on a roulette wheel total 666 when added together, and this bet covers nearly all of them.

It requires placing numerous bets of different sizes to cover different numbers. Therefore, you need to decide on an amount to use as your basic "unit". In the example below, we use £1 to represent 1 unit.

Here's what a typical 666 bet looks like:

  • Stake 36 units (£36) on Red or Black.
  • Then, place 6 split bets of 4 units (£4) to cover 12 numbers of the opposite colour. 
  • Finally, place 5 straight bets of 2 units(£2) on 3 of the remaining 7 numbers.

That would be your 666 bet strategy, totalling £66. It covers all but 4 numbers on the wheel. 

The different bets also offer different payouts. So, if the red/black bet wins, it awards a 1:1 payout, a winning split bet awards 17:1 and a winning straight bet awards 35:1.

It's important to keep in mind that when using this betting strategy, you can win only one of your bets in a spin. Therefore, the potential wins you may get from a 666 roulette strategy may be fairly small, considering the number of losing bets on each spin.

Do Casinos Allow The 666 Strategy?

Yes, casinos allow the 666 strategy. The 666 bet strategy is a legal strategy that roulette players can use in any casino unless it is explicitly forbidden by the casino, which is unlikely. But, if you are not sure, it may be a good idea to ask the casino.

Casinos in the UK seldom restrict betting strategies in their casinos because they do not provide the player with any sort of advantage since they don't affect the house edge of roulette. 

However, they may impose maximum bet limits. Therefore, since this betting strategy covers such a large number of pockets on the wheel, you may need to mind the total amount you are betting and ensure that it is within the casino's limits.

Does The 666 Strategy Work?

The 666 strategy, like all other roulette strategies, does not affect the house edge. They do not provide any sort of advantage over the game. That's why they are better referred to as bet management systems since they simply provide an alternative way to place bets.

While the 666 strategy covers most numbers on the wheel, it still leaves out four numbers, so there is a chance the ball may land on those four numbers. The house edge is still present, and the chances of the ball landing in any given pocket on a spin are still the same.

Roulette is, and will always remain, a random game of chance.


The 666 strategy can be an excellent way of adding variation to the way you place your bets. But, it does not guarantee wins or eliminate the house edge and the game's randomness.

Even though the strategy covers all but 4 numbers on the wheel, only one bet can win in a given spin, so the other losing bets count against any potential winnings you may receive. 

There is no way to overcome the house edge in roulette; it is a random game of chance, and no strategy is going to change that. Remember to always gamble responsibly and do not chase your losses.
