can someone explaine the payout on this ?

[ffextreme]

Can someone explain the payout of this machine? really just the bonus section. It seems like 3 red 7's gets 15 tokens and the big bonus game big bonus pays 8 tokens each spin for 3 rounds of 8 spins 3 blue 7's pays the same. 3 of the symbols same. then it seems 2 red 7;s and a blue 7 or symbol or 2 blue 7's and a red 7 or symbol same payout

I don't understand the second part of the picture it shows 3 jac's will pay 5 + jacin what the heck is jacin and why in the first picture does 3 jacs pay a free spin? then on the right side of the second picture it shows 3 jac's pay 15
I'm a little confused so i hope someone can help me
