They show the free wheel spin every time you might use the faucet its all via website, they will stack up and keep if you are away a while not expire like the free email wheel spin will expire.   Its 1 spin immediately or whatever level you are at and then the rest will take 89 days or more to appear upto a year like above.    Theres no rush and its automatically there anyhow.
   I think the sweet spot level is a bit higher then entry one, the top levels require alot more faith in the token but price is lower now so I still buy tokens but top tiers are for bigger gamblers imo (the biggest gain being the cashback element in potential anyhow).
