Play starts with the Red spin. Betting therefore commences with £1 on Black.
This loses and the next bet of £3 on Black wins giving a net profit of £2.
A new betting sequence is started with £1 on Red.
Play continues in this manner until a loss of the ‘Bank’ of £11 occurs. All three bets in the betting sequence have now been lost.
Ignoring the £9 profit made to date, the £11 is now raised to a number divisible by three i.e. £12, divided by three (£4) and this figure bet as the next bet on Black. Unfortunately this loses and the total loss to date becomes £15. Play continues until another ‘Bank’ loss occurs. As can be seen, another loss of £11 occurs when the accumulated profits for the session reach just £10. This profit is now halved (£5), deducted from the set-aside loss of £15, leaving £10 outstanding.
This £10 is now added to the current loss of £11, making £21 and divided by three (£7). The plan is now to place three £7 bets betting that the run of Reds is going to continue. They do, but only for a further two spins. The third £7 bet loses, leaving a net profit of just £7. This is deducted from the total loss figure of £21, leaving £14 outstanding.

Play continues as before until another loss occurs. Once again, another £11 ‘Bank’ is lost. The profit made since the last ‘Bank’ was lost is £10. This is halved and the resultant £5 is deducted from the outstanding loss to date of £14 equaling £9. This £9 is added to the current loss of £11 equaling £20. This £20 is raised to a number divisible by three i.e. 21 and £7 used as the next series of bets. The first of these wins and the second loses leaving play in a state of equilibrium at-£11. This £11 loss is added to the outstanding loss of £14 to give a new outstanding loss to date of £25. When the next £11 ‘Bank’ is lost the same procedure is followed. The profit of £4 is halved, the £2 deducted from the £25, giving £23 plus the £11 equaling £34. Raising the £34 to a number divisible by three equals £36 which means that the next series of bets will have to be £12 each. Four out of the five bets win giving a net profit of £36. This effectively wipes out all of the deficit and also gives a small profit of £2. When this is added to all the previous accumulated profits of £21 plus the profits made after this last loss, we have a resultant overall profit of £28.
