Pulls & odds

Every capsule holds an NFT. Cheaper NFTs come out more often, and the price follows the average capsule.

How odds work#

Every capsule holds a real NFT. There are no duds.

Each collection has one value. An NFT's weight is one over the square root of its value, so cheaper NFTs come out more often: a Doge Capital NFT (0.3 SOL) is about 6× as likely as a Mad Lads (11.36 SOL).

weight   = 1 / √value
P(NFT)   = weight / Σ weights
P(tier)  = Σ P(NFT) in that tier
EV       = Σ P(NFT) × value

Tiers are labels. Their odds follow from what is inside the machine, never from a setting, and a tier with nothing drawable is hidden.

Why this price#

A pull costs what an average capsule is worth, plus the real cost of buying a replacement, plus 10%: 5% creator, 4% buyback & burn, 1% Hiku. There is no fixed price.

The restock cost is what the machine really pays in marketplace fees and royalties to buy a replacement, measured on every purchase (2%–10%). It is spent on NFTs, never burned. Pulls that strip cheap capsules raise the price a little; restocks bring it back.

One method for every machine#

Every machine and the Global pack price with this one method: the same formula, the same global mix and the same parameters. A creator chooses collections and a trading fee, never how pulls are priced.

  • Two machines holding the same NFTs charge the same price and show the same odds.
  • Prices can be compared across machines: a difference always comes from what is inside.
  • No creator can tilt a machine toward jackpots or cheap pulls to draw players in.
  • The trading fee is the token's own. It fills the machine and never changes the pull price.

Worked example#

A machine with 5 real collections and 35 NFTs, stocked to the global mix. Floors from OpenSea, 29 Sep 2026.

Orders#

Pull x1, x5 or x10. Each capsule is priced at the moment it is drawn, so on the example machine an x10 costs about 8% more than ten times the x1 price. Ten x1 pulls in a row cost the same.

An order is at most x10 and at most 25% of the NFTs available. With fewer than 5 available the machine shows Restocking.

Price lock#

Your pull locks a maximum price per capsule. Each capsule is charged its price at settlement, never more than your maximum, and the difference comes back.

Refunds#

Charged capsule
Your maximum minus its price.
Voided capsule
Your whole maximum, when its price is above it, nothing is drawable, or its average value is below the minimum you set.
No randomness
After about a minute, anyone can expire the request. Everything you escrowed comes back.
Missing prize
If a won NFT is frozen or gone at claim, its price is refunded from the restock pot.
Randomness fee
Never refunded.

Surge#

When a machine is drained faster than it restocks, the price rises by 0.2 × the share of NFTs taken in the last one to two hours, up to +10%. The surge goes to restocking, so bursts pay for their own refill. Odds don't change.
