WaifuHatch
A genetics-driven anime collector. 41 gene loci, 452 alleles, real Mendelian inheritance — every waifu unique by genome, not template.
Pull eggs, hatch waifus, build bond, send them to work or combat, breed them, grind ten into one, climb fifteen ladders. Every waifu carries 82 gene values across 41 loci, expresses a phenotype, renders a unique portrait, speaks lines generated live from her personality + kink + IQ + ATL + mood + recent actions.
Score-based rarity (no dice-roll inflation), dominant/recessive/codominant/blend per locus, breeding mutation 2% per locus, downgrade roll on lucky pairings so two legendaries don't auto-print a legendary. The math is the game.
Explicitly NSFW, 18+ adult gate on entry. Not a porn game in the RenPy sense — sex is one of four tamagotchi verbs. Genetics, breeding, jobs and social systems are the actual game. Professional tone, clearly unprofessional subject matter.

Genome-locked rendering
Every portrait renders from her inherited traits via SDXL + compel weighting. Same genome → same face. Equipment and outfits inject without disturbing body genome.

Live personality LLM
Every phrase she says is generated from her personality + kink + IQ + ATL + mood + recent action history at the moment she says it. Seven locale-locked languages with a background translation worker.

Breeding
Mendelian inheritance with degradation. Multi-round breeding. Visual lineage holds even on unlucky rolls.
Combat
Four combat slugs across four tiers. Turn-by-turn HP tracking. Auto-recall at 0 HP. Strong waifus chew through the roster.
Jobs
Eight work slugs across four tiers. Encounter-based shifts with 22 named clients. Per-(waifu+job) mastery curve.
Live Job Ticker
Server-authoritative WS push at 5s combat / 15s work. Watch every encounter and loot drop as it happens. Five distinct quit reasons.
Pong
PvP minigame driven by gene-derived ATL. Server-authoritative match resolution. K=32 ELO ladder. Combat gear does nothing here.
Poker
Solo NLHE Hold'em vs your own waifus. Personality-driven AI braintree per opponent. Brain inspector. WBG underwriting makes it +EV for skilled play.
Eleven ladders
Four player boards plus seven waifu boards. Face-crop avatars. TTL-cached. Pong has its own ELO board.
Housing
L4 player house with seven optional buildings. Box of Art unlocks cosmetic backgrounds. Letter Box unlocks letters at bond 100.
Letters
High-bond legendaries write you letters at three in the morning. Generated against her current personality. Eligible at bond 100 with Letter Box.
