In my game players collect cards, they mainly get cards from free sources such as opening chests from winning matches.
But they can also buy them in the shop with currency that you also earn but also can buy via dev products.
I want to have a merge system where players can combine cards to have a random chance of getting a better card. But to make the system balanced I wanted to have a currency fee each time you use it, to prevent players from cheating the system to get the best cards.
Since curreny can be bought (and earned), does this go against Roblox ToS? The page I found on policy didn’t seem like it did but am not certain.
The % chances are publicly displayed.
An example just to help illustrate would be:
-player has 3 common cards
-player combines the 3 common cards and has a 60% chance of getting a rare card back, a 30% chance of an epic and a 10% chance of a legendary
-it costs the player X currency to do the merge
-the player is guranteed a card back regardless (but will lose the fee)
