My first 500 spins

Not sure about what sort of roi numbers are thought as solid in spin&go but I think 6.2% is something that is not maintainable in mid/high stake games. That of course doesnt mean it would not be in micro stake even without that solid strategy. 500 is very small sample though for variance heavy format like spins so I would not worry about it.

Its obvious your run started with really big heater and this kind of start will easily make one feel like money just floods in from windows and game is easy. Every poker player will get these and also runs where things dont go your way at all. Plus everything in between. So its not about short term result but about making good decisions consistently enough and improving your strategy.

Thanks for replying.

How many spins do you think that is a enough sample to be sure that a player is profitable? Also I play the "flash" ones, it's a minute for each blind level.

Well few thousand at least.

If every spin start with the same amount of chips (300 I assume) and it's mostly winner takes all, it's more adequate to measure your success by looking at your chip EV.

In stars, 10x + multis have ICM, so just filter the 2x to 5x multis only.
