Ah, okay. It says I have 7 boosts, but 0 distance + 0 nitro so I can't click it. It seemed like people started with fuel too but maybe I was mistaken.People got initial rewards based on their account "value." So people with tons of games started with a lot of boosts to use. I had like 24.
To refuel it tomorrow I'll just cash in my 20k points I have waiting from Divinity Original Sin 2.
