The chance displayed on screen is the chances of the exact sequence of buttons you picked for example if you pick red then blue there is 25% chance you picked that shown as 0.25
May not be entirely accurate due to peoples choices being more inclined to pick some patterns then others. Also thank you everyone for over 500 views!! E.g It is more likely you pick red red red red red red than blue red red blue because you can just spam (it actually shows the percentage for the next one you will pick soz) Hold down h,e,a,r,t keys at the same time for easter egg comment I found the easter egg! Also you can't actually click the buttons in this mode restart if you want to play the game..
