If you play the 20+2 sng and your Roi is x written in decimal form (percentage over 100) , then your net profit is (21.46)*((1+x)/)-21.46= 21.46x

Your net profit for the 25+2 game is :

27y

27y>21.46x
y>21.46x/27=0.79x


This means that if your Roi is 50 % in the 21.46 game , then you would need an roi of 0.79*0.5= 0.395 to play in the pstars game .
