(i dont know if this feuture is still there, specially if the gui changed alot since my last visit) in mobile there was a roulette in many games wich worked like this: see an add, and get things
for example, in hunger games (and sky wars i think) you started with a random loot.
however, this is (or was idk) only on mobile, i think it should be on pc.
this was specially helpfull in hero tycoon 2 when gcubes came to
i think it should be on pc
