Back on Only one has 21 pts with partial loss recoupment
Back on selection "Only one has 21 pts" after it has lost 3 consecutive games. If the bet has lost, double the stake and back again in the next game. If that bet lost too, revert to the original bet size and keep backing until win.
After the win reset the stake to the initial size.
Once a specific profit target has been reached, stop betting and close the channel.
To change the profit target simply edit the "Value" field of the only constant named profit_target. In the example it is set to 30 currency units.
