I visited Metawin, then clicked on Metawin Originals and I got so sad when I saw Plinko 99 instead of Plinko 101. Btw that is an amazing promotion from Metawin. 101% RTP means that players are guaranteed to profit 1% of their money and chances grow the longer they play it. Besides 1% profit, they'll be able to wager lots of money, get Metawin points and get some cashback from Metawin for their wagering.
That sounds very great offer from Metawin to their users. As far as I understand, 101% RTP is good and surely better than 99% RTP but on user side, it's up to them for playing wisely to increase their chance to win and get profit from their initial money for gambling and total bets they make. It doesn't mean all users will get profit whatsoever playing strategy and actions they made through all their bets.
Experienced gamblers can have higher chance to get "guaranteed" profit than newbie, non-experienced gamblers, as always true in anything.
I am curious about it too.
