This method is a classical type of a double bet. Besides two
required double bets, it also requires addition to the winnings.
Because of this, the effect from the double bet is noticeably
increased. The feature of this method is that it, as none the rest, gives
a lot of possibilities for the individual development. You can make it
the base of a big game, its structure allows to use it for a modest
game with the profit expectations of 15-20 units too. The technology
of the bet is following: three chosen chances play with bank
simultaneously. Every time put one unit to the won one. This goes
the following way:
· 1st spin - place one unit, one unit is gained;
· 2nd spin - place 2 plus 1 units, total three, 6 units are gained;
· 3rd spin - place 6 plus 1, total 7, 14 units are gained.
After this we start with the first bet again. Also after any
intermediate loss place one unit on a respective chance again. Using
this scheme play all three chosen chances simultaneously. If the loss
of 20 or more units happens as a result of the game, all the bets
should be doubled. If deterioration approaches again, the bets should
be double again. Now, instead of one unit on each chance place four.
After achievement of the above-zero condition we return to initial
bets.
