its basically just a chase system where if you lose a game you increase your next bet to make profit. Basically its saying you shouldn't lose 7 in a row or your just awful at betting. and if you do then your down a lot. But if you win one out of every 4 then your making profit instead of covering 1 loss. It usually takes a decent size bankroll but it's worth it if your not afraid to keep uping your bet amounts after a few loses.
