We can't precisely predict when does 15-20 red streak come and go, because that is gambling we can not predict the accurate result or outcome of every game, we will only hope for our luck on that day, but there are some ways to know what would be the output of the game, based on what I had read before a man won in the lotto because he observed and analyze the process of the draw lots, he is a statistician, so by doing some statics of the lotto for four months, he came up with the correct output. He is now a millionaire because of that. You can make statistics In every gambling that uses a machine to operate the game because the same process will be applied to start the game. The machines are already program to start the game with the same process, so if you will make ways and if you are going to do some research, then probably you will win the game. Gambling is better if you win the game, so for you to win the game, you should do some research and analyze the process of the game. It is better if you are going to make a way to win than to wait for you to win.
