Clarify me also if plinko is a game of luck. Thanks in advance.
There is no such thing as Plinko strategy. It's a game of chance.
Most of the articles claiming to explain how to win at Plinko which you can find online are from the perspective of the casino sponsor. Such articles usually offer a few ideas and only after digging into a short 'tutorial' will you find they have no point.
what more can i say. if the OP is searching for a method or strategy to win on this game, there's none. it is luck-based game like dice or crash. i dont consider this game to have specific strategy to win. but you can minimise losses depending on your betting strategy.
that's right, those strategies published is one way or another under the blog of a specific casino.
