User rating

Every registered user can rate any game in the BGG database. Although these ratings are entirely subjective, here are the suggested guidelines:

  • 10 - Outstanding - will always enjoy playing and expect this will never change.
  • 9 - Excellent - always enjoy playing it
  • 8 - Very good - enjoy playing and would suggest it.
  • 7 - Good - usually willing to play.
  • 6 - Ok - will play if in the mood.
  • 5 - Average - Slightly boring, take it or leave it.
  • 4 - Not so good - but could play again.
  • 3 - Bad - likely won't play this again.
  • 2 - Very bad - won't play ever again.
  • 1 - Awful - defies game description.

How to do it?

To do this, find the game and go to that game's Main Page; this is most easily done using the Search option near the top of every page. In the topmost section is a series of stars labeled "My Rating", which you can click on to set your rating on a scale from 1 to 10 (once set, you can click on edit to use decimals). You can alternatively go to your In collection drop-down arrow, click on Edit and fill your rating there.

Precisions

All recorded User Ratings are averaged to produce a single Average Rating shown in a game's "Statistics" section.

If a user has and rates several copies of a game in their collection, then only their highest rating for the game is used.

BGG does not allow people to give multiple ratings to a game through the use of separate accounts.

Sometime around 2017 it was decided not to display on a game's main page its average User Rating if the game has fewer than 30 ratings (since a small number of user ratings can be so extremely variable).

It was later decided to nonetheless show the average rating if the game had been in the database for over a year and was still struggling to get 30 ratings.

Common proposals and complaints

Various ratings-related proposals and complaints appear repeatedly in the forums.

  • Very many diverse proposals for "improved" formulas, sometimes including purported "mathematical proofs" that the new proposal is clearly superior.
  • Complaints about low ratings perceived as malicious or trolling, with various proposals to disallow such ratings (which are complicated once one tries to formalize them in detail, e.g. how to define and prove a "bad faith" rating, how to police them, etc).
  • Complaints about ratings wars between 10-raters ("Cool minis, can't wait for this game!") and 1-raters ("Countering the hype!")
  • Complaints about ratings for unreleased games, with various proposals to disallow rating unreleased games (which are complicated when trying to formalize them in detail, e.g. how to define an unreleased game, how to police this, what about playtesters and others who really have played it, what about games with multiple versions & editions, etc).
  • Proposals for different text descriptions / meanings of the values 1-10.
  • Proposals to only allow people to rate games which they've played, or which they own. (But many users have no interest in logging plays or marking their owned games. And nothing prevents users from falsely logging fictitious plays or falsely marking a game owned.)
  • Proposals to only allow people to rate games if they also write a user comment about the game. (Which would probably cause an increase of hastily typed useless vapid user comments.)

Current BGG policy is that users are allowed to rate games however they wish, as long as each person only rates a given game once.

Ranks

The User Ratings are also used to determine the Rank of a game (not expansion) in the BGG database. Only games that have at least 30 User Ratings are eligible for Ranking and to the User Ratings are added a number of "dummy" ratings, which are then used to produce a new average Geek Rating. (E.g. see this thread.) This is the rating that shows up in BGG searches and the number can, and does, vary from the Average Rating. In effect the "dummy" ratings move a game's average towards the norm of all games on the database - making games with few votes but very high ratings lower ranked than games with many more ratings but a lower Average Rating. (If you want to know more about this process, search on "Bayesian" within BGG.) Additionally, secret undocumented stuff is done to try to filter out obviously bogus "shill" or "hate" ratings. (There are many threads from people asking about or trying to figure out the details, but they are intentionally undocumented.)

Note that the number of "dummy" ratings apparently depends on the total number of ratings. This explains the apparent "paradox" (often asked in the forums, e.g. here) of why game X is higher ranked than game Y overall, but game Y is higher ranked than game X in subdomain Z.

Another rating: weight

A further rating you can give to a game is the Game Play Weight. This is another personal opinion expressing how difficult the game is to play - either because it has long and/or complex rules, requires deep thought to play well or some other factor. "Weight" is not actually defined at BGG so different people have different ideas of what it means. The choices for Game Play Weight Are:

  • Light
  • Medium Light
  • Medium
  • Medium Heavy
  • Heavy

How to do it?

Click on the Weight or the 'Complexity' rating. It will display the current *results*. Press *Go to Poll* button, select your option and press *Vote*. It is done and the system remember your vote (you can change it).

All recorded Game Play Weights are then averaged to produce a single Game Play Weight that is shown in the "Statistics" section for each game as Avg. Game Weight.
