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 in the article below. 

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

What Is the 666 Roulette Strategy?

The 666 roulette strategy is a betting system that aims to cover almost all the numbers on a roulette wheel. It is named 666 because the numbers 1 to 36 add up to 666, and the bet configuration seeks to cover nearly all those numbers.

You must place several bets of different sizes, so first choose a basic "unit" size. In the example below, £1 represents one 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 totals £66 and covers all but four numbers on the wheel. The different bets have different payouts: a winning red/black bet pays 1:1, a winning split pays 17:1, and a winning straight pays 35:1.

Bear in mind that, on any single spin, you can win at most one of these bets. Because many bets will lose on each spin, the net win from a successful outcome may be relatively small compared with the total amount staked.

Do Casinos Allow the 666 Strategy?

Yes. The 666 bet strategy is legal and generally permitted in casinos unless a venue explicitly forbids it, which is unlikely. If in doubt, ask the casino staff before you play.

UK casinos rarely restrict betting strategies because they do not change the house edge in roulette. The strategy gives no mathematical advantage, so it is not typically treated as a rule breach.

Casinos may, however, enforce maximum bet limits. Because the 666 strategy covers a large number of pockets, check that your total stake falls within the casino's table limits.

Does the 666 Strategy Work?

The 666 strategy, like all roulette systems, does not change the house edge. It offers no advantage over the game and is better described as a bet management system because it only alters how you place bets.

Although the 666 strategy covers most numbers on the wheel, it still leaves four numbers uncovered. That means the ball can still land on those pockets, since each spin has the same probability for every pocket.

Roulette remains a random game of chance with a persistent house edge.

The Bottom Line

The 666 strategy can be a useful way to add variation to how you place your bets. It does not guarantee wins, remove the house edge or change the inherent randomness of the game.

Although the strategy covers all but four numbers on the wheel, only one bet can win on any given spin. The losing bets from the same spin will reduce any potential winnings you may receive.

There is no method to overcome the house edge in roulette; it remains a random game of chance and no strategy will alter that. Always gamble responsibly and do not chase your losses.
