This is one invented by a Canadian many years ago.

It is like the Cancellation System above with this
variation:  When winning, (add the first and last
number in the sequence), the first time, and then
3 numbers until you lose. 

If you lose, add that to the end of the sequence 
and bet only the first (only one) number not crossed
off. If you lose again, go to betting the unit bet, 
to preserve capital. 

I have found one needs about 40 times the first 
number in the sequence when starting as a bankroll, 
with the initial numbers being about 40-20-20-20 % 
(i.e. $50. sequence would be written: $20-10-10-10.) 
Your bankroll taken to the table will be $1000.00.

This means, I've found that you only have to win 
30% of the time to be successful! I have used this 
very successfully in the casinos, to the point that 
I was asked to leave the table several times, as 
the casinos don't want consistent winners.  
It scares them. 

This system requires nerve, fearlessness and an 
appropriate bank roll.  When playing Baccarat, I
was winning $4000 an hour, but again, don't back
off pushing the money out, or you will lose.

The system really forces one to bet large when
winning and small when losing, which is exactly
the opposite of what most people do - and what
the casino expects.  

You also need high enough table limits.  It can
be used playing blackjack, baccarat or roulette,
but is best for blackjack.  Make sure you get 
their OK to write the bets down before you start,
and tell them you are not counting cards.
