On the other hand it is possible to exchange madpoits against Rounds at lucky you (game of the month) 10 Coins = 100,000 MadPoints 10 Coins = 5 credits
so we can say that 1 credit is equivalent to 20,000 MadPoints
at CadoVillage you can Play fishing Points in Fish A Prize 2 and in the different trip tic.
No, we have to buy the credits. The most interesting thing is to buy them "in bulk" (when we pay them by credit card, there is a discount on their amount).
