Breed real morphs
Over 100 genes, taken from the real morph lists. Plan a season, prove out hets when a visual baby hatches, and chase the combos everyone wants.

A ball python breeding game with real genetics and one shared clock.
Games / Lock and Lay
Pair a female and a male, wait for locks and ovulation, incubate the clutch for about 58 days, then cut the eggs one at a time and see what you made. Every baby follows real ball python genetics: recessive genes hide as hets, co-dominant genes make supers, and Mojave x Lesser makes a Blue Eyed Leucistic one time in four.
Lock and Lay trailer, 1 minute 12 seconds. All footage is real gameplay.

Over 100 genes, taken from the real morph lists. Plan a season, prove out hets when a visual baby hatches, and chase the combos everyone wants.

Every gene combination is drawn as its own 3D animal. Hold them, check their weight, watch them shed, and treat the ones that get sick.

Buy racks, lay out the room, add an incubator, a feeder freezer and plants. Feed, weigh and keep the humidity right.

Everyone shares the same calendar, so your animals grow, breed and hatch on the same day as everyone else's. List your babies, trade with other players, and enter the Expo Hall and Best in Show.
Lock and Lay is a game. The genetics are simplified for play, so use real breeders, vets and care guides for real animals.
