Dating for people with a shelf of shame

Your BGG collection says more about you than your bio ever could. The games you have rated 10, the ones you taught at every game night, the 3-hour euro you evangelise to anyone who will listen. That is compatibility data.

How it works for board gamers

Connect your BGG account. We pull your collection, ratings, play history, and wishlists. Nothing is shared raw - only derived signals. All opt-in, all revocable.

The algorithm understands that board games exist in layers:


Niche overlap > mainstream overlap

Both owning Catan? That is a popularity 95 overlap. Everyone and their mum has Catan. It barely registers. Both owning and rating Barrage a 9? That is a signal.

Mainstream
Catan
Ownership 95% → NicheWeight 0.05
Niche
Barrage
Ownership 8% → NicheWeight 0.92

But it goes further. The algorithm knows the difference between "owns it, played once, forgot about it" and "played 47 times, rated 9.5, taught it to everyone." Play count and ratings turn a flat collection overlap into a real affinity score.


The core signal

A BGG collection is not a personality. Anyone can click "own." What matters is how you engage with your games.

Did you play it 50 times or once? Did you rate it a 9 or a 6? Do you own the expansion? Are you in the forums discussing strategy? The algorithm captures engagement depth - play counts, ratings, collection depth - and uses it to separate genuine passion from shelf decoration.

Complexity preference matters too. Someone who lives in the 4.0+ weight range on BGG has fundamentally different game night expectations than someone at 2.0. The algorithm treats this as a compatibility factor, not just a filter.


What gets scored

Shared games weighted by how niche they are (BGG ownership percentage across all registered users)
Shared mechanics - not just "both like strategy" but the specifics: worker placement, engine building, auction/bidding, hand management
Play count depth - total plays per game, frequency of play, how recently you played
Rating alignment - both rating the same niche game highly is a stronger signal than just both owning it
Complexity preference - your average game weight on BGG reveals whether you want 20-minute fillers or 4-hour brain burners
Wishlist overlap - shared games you both want to try is a forward-looking compatibility signal
Shared dislikes - both rating a popular game low or trading it away. A mutual dislike of Monopoly is universal; a mutual dislike of a popular euro is niche
Player count preference - do you prefer intimate 2-player games or big social 6+ player nights?

Example match

"You both own and rate Brass: Birmingham 9+ with 30+ combined plays. You share 12 games in the 3.5-4.5 weight range with a combined NicheWeight of 4.8. Mechanic overlap: engine building, route building, economic. Your average game weight is within 0.3 of each other. Wishlist overlap: 3 games including Ark Nova."

Not "you both like board games." The actual collection. The actual taste. The actual weight class.


Game night compatibility

Board gaming is inherently social - and often happens at home. Finding someone who wants to play the same kinds of games, at the same complexity level, for the same duration, is not a nice-to-have. It is the foundation of a compatible evening together.

The algorithm considers practical compatibility beyond just taste. Do you both prefer 2-player games? Do you both enjoy teach-heavy games or prefer ones you can learn as you go? Is your collection complementary - do they own the games you have on your wishlist?

A shared love of a niche mechanic like 18xx or wargaming is an incredibly strong signal. Those communities are small, passionate, and time-intensive. Finding someone in your area who shares that specific interest is exactly the problem Affinity Atlas solves.
