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.
200k wagering is a big deal. I have seen many people recommending plinko to fulfill this wagering. It is not as easy as they say. Nothing in gambling is easy, everything is very risky. To make a 200k wagering, you must gamble with the mindset of losing a large amount. It is very difficult to fulfill this from any game, but by playing plinko, Helo, crash, dice, such wagering can be fulfilled, but the loss will definitely be here and you have to accept it. Such a big wagering can never be fulfilled completely risk free.
I never indented to say that its easy or risk free to wager 200k in plinko. But for me it seems as one of the cheapest way to do that if we dont into consideration luck. Because in worse scenario (bet loss), bettor loses only half of his bet instead of losing it completely. It can be said that maximum 100k would be lost in worst scenario
Imho building wager in plinko is much easier trying to catch huge multiplier in crash, dice or hi-lo
