To be honest, wagering 200k only sounds scare. Or maybe I have wrong understanding how wagering and some games really work. Playing plinko with minimum rows seems to be the easiest way to wager. Only if the ball hits the centre, you will lose half of your bet, while the rest balls will hit 1 or 1.1 multipliers. I have run a test, dropped 100 balls worth 1 cent each bet, ended with 93 cents by the end

Only con is that it will take days to wager 200k gambling like that.
