Pops determine which robot mode is next, but i cant believe we havent had TF/TFLE mentioned (that i saw).

5 decepticon robot modes (Megatron is 4ball mb)
5 autobot robot modes (optimus is 4?ball mb, mudflap/skids is 2ball mb)
Rules for megatron/optimus change if you are playing red or purple side
Bumblebee captive ball starts timed double scoring mode
Mudflap/skids target starts timed (all shots worth x) frenzy mode
Completing red robot modes has rollout mini wizard mode
Completing purple robot modes has all hail megatron mini wizard mode
Completing both red and purple has a unobtanium final wizard mode
Tfle adds starscream left ramp mini mode and ironhide right ramp mini mode.
I dunno if these are in the pro or not, but ironhide awards you super pops, super spinner modes
