Hello, I'm trying something a bit tricky. In the main menu of my game, the player can check in a list of all the levels the maps he wants to play. I would like to match the players according to that and select a map that was checked by all the participants.

For that, I can set as match data the list of all checked items (the names of the maps as a list of strings), and I feel like I should make a custom query to check the intersections of the lists, but I have no idea how to do this query.

Maybe I need to enter the list of the maps as custom game data in Game Sparks to make it easier.

Thanks in advance, thumbs up for this awesome platform
