I used to be able to use jinxie's jamboree to be able to afford to revive my pet/heal them, but now that each spin costs 5 G, I ame pretty much broke, and I accidentally gave Cereth the information of Queen Annabelle. Please help!

I see that your pets are revived as of this moment.

But if you didn't know, you can always remove them from your Party and they will self revive and heal up over the course of about 30-60 minutes. You don't necessarily have to remove them from your Party, but there are some stages of the game where it won't work (like if you're explore the MegaZone once it's released). So you can always guarantee it by just removing them from your Party.

That said, once revived, I'd suggest going to Trollsbrlight Caverns and grinding for a bit and then selling all of the Equipment you find that isn't an upgrade for your pets. This will give you a decent amount of Gold to work with.

I'd also suggest setting up some Missions pets and doing as many Missions as you can do. This will yield a lot of Gold, Equipment, and Consumables.

Lastly, to specifically answer your question, the minimum cost to play Jinxie's Jamboree has always been 5 gold.

When I first started Sylestia (not too long ago, I assure you), Jinxies Jamboree was free.

Jinxie's Jamboree has never been free. =P

It has always cost a minimum of 5 gold per spin and a maximum of 10 gold per spin if you've completed Umbra Forest (I think that's the requirement to unlock the next bet option).

Okay, I only unlocked tier 1
