The prize a pack can pay is limited by the free coins in the prize pool. A new machine has only its seed: the coins the creator buys at launch. The seed decides how large the first jackpots can be.

The mandatory seed

Every launch buys a mandatory seed. The program sizes it on a reference pack of 1,000,000 coins:
For the app’s table, whose top row is 8×, this is 2,000,000 coins. With that seed, a 1,000,000-coin pack can pay up to 3,000,000 coins: its own coins plus the seed. A table whose top row is below 3× needs a smaller seed. The mandatory seed is always bought, whatever the creator chooses.

The backup seed

On the create page, Starting liquidity sets how many full jackpots in a row the seed should fund. A jackpot is the table’s top prize, 8× on the app’s table, on the cheapest pack at the launch price. The app offers at most 5 jackpots. It also hides any step whose seed would cost more than 10% of the curve’s graduation target. The first jackpot needs the top prize, less the pack’s own coins and the mandatory seed. Each further jackpot needs the top prize less the next pack’s coins. Larger packs have larger prizes, so the same seed covers fewer of their top prizes.

The seed is a gift to the prize pool

All seed coins, mandatory and backup, belong to the prize pool for ever. The creator cannot withdraw them. Later packs and coins the creator funds add free coins. Large wins use them up. The app always shows the current payable prizes before a buyer signs.

A seed moves the price

The seed is bought on the curve, so a larger seed raises the coin’s starting price. Later packs then buy a little fewer coins. The seed also counts toward the curve’s graduation target. The seed buy pays the curve’s trading fee, but no pack fee. See Launch a machine and Prizes and odds.
