Why the lists keep failing
A code list is a coupon on the fridge: by the time you spot it, the deal is already over. The roll doesn't wait for a coupon. You throw two dice, and the spins follow that number.
Codes for Anime Dice arrive with each update or a milestone, and the game turns them off later. Guides repeat each other, so a code can stay on page one long after it quit working, and the redeem box only tells you when you type it. The drop on the next page needs no code: your two dice set the Jackpot Spins, total times five, and the Lucky Spins, Trait Rerolls and Gems come with it.
Spins are pulls
Every spin is one more try at a unit like this one. Lucky Spins tilt the odds, Trait Rerolls fix a bad trait, Gems upgrade what you keep. More of each means you climb faster.
