Almost, but you can't define the price in virtual currency.

The solution I came up with is to make a cloud script that purchases and then immediately sells a user item. The user item has a buyPrice and a sellPrice which effectively does the currency conversion.

You can schedule a recurring daily cloud code script to run after the completion of your daily tournament. This script will use the GetGlobalLeaderboardPage method to retrieve the daily tournament winner's information and score, then post it to the monthly tournament using the PostTournamentScoreOnBehalfOf method.

Thank you! I've hacked an implementation for now that just guesses the ranks on the client side without grabbing the actual ranks. The players will only discover it if they're playing sitting side by side. 🙂
