Roulette Dozen Bot Software
Most roulette systems revolve around even money bets (like red/black). But probably the next favorite for bettors is to play on a system of dozens and columns.
There are 2 basic variants (in other words similar to Martingale) where you increase your bets to make a profit again after a loss. Test them out in our free roulette games. In one variant, you bet a single dozen, and in the other you bet 2 dozen. You can visit our website to buy roulette dozen bot software.
