~ if you got two different colors in the first two steps still you can click the third one from my side.
Won straight three green while doing this.

I don't understand how you can get three green if your first 2 are already different.
But I think I am understanding it better:
Say you have 2 different colors on the first 2 tiles you opened, (1st blue and 2nd green for example), and the third will be red.
What would the payout be?
is it the payout for
1 blue: 0.45
or/and
1 green: 0.50
or/and
1 red: 0.75
Tried the game recently and I can say that your payout for above case is 0.45, and in other tries:
- I got 1st red 2nd blue and 3rd red, my payout is 0.75
- I got 1st and 2nd blue 3rd green and my payout is 1
- I got 1st green 2nd blue 3rd green and my payout is 0.5
Based on these tries, I think the first one is the one to decide your payout in case you get different color for the 2nd one unless you get the X symbol as it will make you lose the bet.
