What is on the wheel changes every show — there is no fixed line-up. The pool is simply the set of prizes available that day, loaded onto the wheel before the stream starts and shown on camera so you can see what is up there.
Graded slabs
A slab is a single card sealed in a hard plastic case by a grading company, with its condition score printed on the label. It cannot be opened without breaking the case.
PSA-graded singles, scored 6 to 10 for condition. The grade is on the label and it is held up on camera before the spin, so you can read it yourself.
Sealed product
Sealed means unopened, exactly as it left the factory.
Booster boxes, premium boxes and collector boxes. Some go on the wheel whole as a single large prize. Others are opened and split into individual packs across several slots.
Single packs
Individual booster packs pulled from a mix of different releases rather than one carton of the same thing, so what you can land on actually varies.
