What can I use coins for in Bingo?

[Butterflybaby73]

I'm new to the Bingo app and I've looked everywhere I could think of and can't figure out what I can use all of my coins for? Is there a way I can use them to buy tickets? Or to buy gems to buy tickets? Thanks to anyone who can help me!!

You use coins to buy crates (the things that give you boosts while you're playing), keys to open chests, and bingo cards in the regular tournament.

You can only buy tickets using gems.
