1,000 sealed eggs, and every one sold makes the next one dearer. Nothing inside is decided until it cracks. After that it grows only by beating beasts other people own, the young die for good, and anyone watching can put money on a fight before it is answered.
Nothing hatched here yet.
An egg is one of a thousand, eight per wallet. The account holds a zero seed: the animal does not exist yet. An hour later you crack it, and the seed is fixed then from a slot hash: one of thirty species, an element, four stats. That is why the reveal is a reveal.
There is no feeding. A win is ten experience, a loss three. Thirty makes a teen, a hundred an adult, and each stage multiplies all four stats. Growing up is also the only free heal in the game.
Damage stays on a creature and comes back at one hit point every two minutes. Knocked to zero from half health or better, it is carried out on one. Knocked to zero after going in wounded, it is gone. Adults cannot be killed.
A posted fight stands for an hour at most. While it stands, anyone can put money on the posted beast or on whoever answers it. When it settles, the side that was right splits the side that was wrong, less the house cut. Pull the fight back and everybody gets their money returned.
The first egg is the cheapest one there will ever be. Every egg sold raises the price of the next by a fixed step, written on the colony account, so what it costs is arithmetic anyone can check rather than a number somebody announces.
Two adults make an egg. Each of the eight genes is a coin flip between them, and about one in twelve mutates into something neither parent had. Both rest three days, and neither raises more than five.
