No it is not the cheapest one, there is a cheaper buy bonus than choco reels. The game is Gaelic Gold by Nolimit City, it costs you $2.5 only for a base bet of $0.05. This game has 9837x max multiplier from the base bet so basically with $2.5 buy, you can win up to $491.85 which is more than 190x of the cost of the buy bonus.
Well what I mean was the cheapest buy on choco reels not for the entire slot games, since that slot has two options of bonus buy features.
Btw, thanks for bringing the Gaelic Gold up. I didn't know much about the games from Nolimit City (unless the popular slots) so I'm not aware of Gaelic Gold and it has a really cheap bonus buy, perhaps I will try it later and record the game session to participate in the current youtube contest. ~lol
About begging, In every casino begging is prohibited on the chats most of them will get muted or banned when you are begging.
you will see this begging every day in rollbit Twitter.
I guess it's a common view in social media, particularly if the casino has lots of active users and has good promotions inside of the platform.
