Ion,
The 'Turnaround' gambling system was placed on the Internet by its founder, Ian harmer. The system was apparently not for sale at any point, and was placed on the Internet to 'assist' casino gamblers (free of charge). You'll find the Turnaround rules at:

• Editor's note –
I did "meet" Ian Harmer in newsgroups in 2003. He was prophesizing again his "Turnaround" system in the blackjack newsgroup. I presented the mathematics of his system. I also opinionated again that he was some casino man, a mole for the casinos. They, the kasinos, know that most casino players believe in gambling systems. Well, then, why not offer players gambling systems created by the casinos, for increasing the advantage of the casinos? That's the purpose of a gambling system such as Turnaround. It DOUBLES the house (casino) advantage. That is, a turnaround would DOUBLE the player's disadvantage!
Ian Harmer (he is harmful alright!) drowned in a sea of silence. He folded up, or mysteriously…turned around!
• Ion Saliu on gambling/betting systems based on doubling/increasing the bet after each win, such as Turnaround -
The wins and losses can be counted as streaks. There are two categories of streaks: single win/loss streaks and multiple wins/losses streaks.
The number of streaks can be determined by mathematical formulae. I will not post formulae here. If you don't trust me, do some researching of your own and at your own cost! ( I am not implying that trust should be enforced!)
Of course, the number of streaks is dependent on the probability of the event. Let's consider here the event of a roulette player betting on red/black at double zero roulette (even money, or 1-to-1, or 1-for-1, or 1-on-1; it's even because both terms are equal).
The probability to win is closely equal to 0.474 (pW = 18/38 or 47.4%).
The probability to lose is pL = 0.526 (or 1 – pW).
1) WINNING streaks for the player:
• 130 single win streaks (W) in 1000 spins
•• 118 multiple win streaks (2 or more Ws: WW, WWW, WWWW, etc.) in 1000 spins.
2) LOSING streaks for the player:
• 118 single LOSS streaks (L) in 1000 spins
•• 130 multiple LOSS streaks (2 or more Ls: LL, LLL, LLLL, etc.) in 1000 spins.
The ratio 130/118 = 110.2% shows the advantage of single win streaks over multiple win streaks, OR, equivalently, the advantage of multiple loss streaks over single loss streaks. You can bet baby milk money on the fact that the casinos know extremely well about that ratio. There are games (sluts, anyone?) that offer to the player, after every win, this wager: "Double your win?" or "Bet it all?" That is, if you win 1 unit, your total becomes 2. The casino wants (badly!) that you bet 2 next. The percentage greatly favors the house. Every player should be very suspicious when such a betting "system" is offered.
