Good day sirs !
The /jav/ Marriage Survey Gacha 2025 season is coming fast. Let's break down how this edition will work shall we.

>General rules
The game consists of 10 rounds, one per week.
In each round, every villager will be assigned exactly one javlet through a semi-controllable Gacha.
The draws are unique: each actress can only be assigned to one player per round. Once REDEEMED, the actress can not be picked on later rounds.
Each week will have two phases: the POOL & the LOTTERY.

>POOL creation
Each sir submits 3 unique and non redeemed actresses between Friday and Sunday. The submission order matters (for future use let's call them Pick 1, Pick 2 and Pick 3). Submissions close on Sunday evening.
If two or more players pick the same actress in the same slot (e.g. two identical Pick 1), that actress is REMOVED from that slot for all players.
This applies independently to each slot (Pick 1, Pick 2, Pick 3).

>LOTTERY
The draw happens on Tuesday, probabilities for each player are as follows:
Pick 1 40%
Pick 2 20%
Pick 3 10%
Remaining actresses in the pool (i.e, actresses named and available in one pick level by other players but not picked by the player) 30% evenly split

If one of a player’s picks was removed due to a VOID, their odds are redistributed.
Example: if Pick 1 is gone:
Pick 2 20% ,
Pick 3 10%
Remaining actresses in the pool 70% evenly split

>For the Nerds
I don't want to be too technical but to keep the game fair, the lottery uses weighted random sampling without replacement. This means:
Players don’t draw one after another. Instead, the system considers all players and all actresses at once.
The weights (40/20/10/30) are used to give each player their proper odds.
No actress can be given to two players: once someone gets her, she’s gone from the pool.

I will use a Python script using the Efraimidis–Spirakis algorithm.
Each possible actress for each player has a weight (based on the odds).
For every actress, it will generate a random number that depends on its weight.
The higher the weight, the higher the chance of getting a “better key”.
It will arrange all players by their random keys and then assign actresses to players in order, making sure no actress is used twice.
Think of it like each actress rolling a dice that is biased by how much a player wants her, the more wanted she is (Pick 1 vs. pool), the better her chance to “win” the dice roll for that player.
Then the script takes the best dice rolls across all players and assigns actresses without repeats.

This way, the draw feels random but fair, your Pick 1 really has about 40% chance, conflicts and removals are respected and no actress can end up assigned to two players.

>NOTES
Legal javlets: they must have filmed a professional JAV, they may be active or retired. Actresses redeemed in the 2024 session are out from the game.
A non player (Cuckguy) will "play" and receive actresses from the pool without submitting any names. His odds are evenly split from the pool.
Two special rounds: round 7 "droit de cuissage" where names from the 2024 session will be legals two join a second household (it's not a divorce !) and round 10 where 5 names will be submitted, 3 draws by player.
An illegal submission will cancel the round for said player. Cheating (same IPs for alts, using VPN...) will remove the player from the game and make his wives legal to play again.
It won't be possible to enter the game past round 3.
