Can a free user can have a chance to get 2 slot

You mean you don’t want to/can’t purchase one?

Even without spending money… Is there a way getting 2 slot of hero

No. I think this is one of the main ways the game makes any money from players. Think of that $1 as paying less than $0.01 per hour you play this game! Much cheaper than a night out at the bar or something.
