Play roulette (the digital one) on instant bet $5 on red and 5$ on black
Occasionally you'll hit green but you have to take some loss there's no way around it,
By losing 20$ you can easily wager upto 6k $, it totally works
If you're hesitant about losing more start with 1 or 2 $ and put a stop loss of 10 $
It worked for me by losing 10$ I was able to wager 2600$.
