Purpose of coiner and casino mode ?

[Aradhor]

Hi
So question is simple. Do these do anything different aside from a fewer coin to begin with ? I mean is there any special reward or that's just for difficulty and fun ?
Thanks

i think you have a better chance to have bigger tokens on those diff levels, but i also have the luck skill so, can be a coincidence ^^
