1:15 use the Adv. Random trigger, for each group you give a number (in this case all 8 gamemodes would have the same number), the group with the smallest number has less chance, and the group with the higher number has higher chance. Here's an example: you use any group for each gamemode, and in the other box you put all numbers from 1 to 8 in order of each gamemode, since the cube has the number 1, it has the lowest chance, while the swing, that has the number 8, has the highest chance. I don't know if this helped. Edit: 1:40 also, you can enter the options of a protal to enable free mode, you'll need to select each one individually because they are different objects with different IDs
