If your game is an expansion of another game (or another game has expansions), Boardssey models the relationship explicitly. The base game shows its expansions in a dedicated tab, and your public catalog surfaces the family relationship to visitors.
This page covers marking a game as an expansion, linking it to its parent, and what that does for the rest of the app.
What this page helps you do
Mark a game as an expansion.
Pick the parent (base) game.
See expansions listed on the base game's page.
Mark a game as an expansion
When creating or editing the game (see Create a game):
Open the game's Game info tab.
Find the Is expansion? toggle (or similar).
Turn it on.
A new field appears: Parent game. Search and pick the base game from your library.
Click Save game.
The expansion is now linked. From here:
The expansion's header shows the parent game's title.
The base game's page gains an Expansions tab listing this expansion and any others.
The public catalog (when enabled) shows the relationship.
See expansions on the base game
Open the base game (not the expansion). You'll see an Expansions tab on its page. Every expansion you've linked to this base appears there with its cover, status, and a click-through to the expansion's own page.
The Expansions tab also has a New expansion button, clicking it creates a new game pre-marked as an expansion of the current base game, saving you a step.
Public catalog
If the base game and its expansions are all toggled on for your public catalog (see Add a game to your public catalog), visitors see the family relationship: each expansion's catalog page indicates its parent; the base game's catalog page lists its expansions.
If the base is public but an expansion is private (or vice versa), only the public ones appear; the relationship is hidden where one side is hidden.
Switching the parent
If you marked an expansion under the wrong parent (or you split a base game into two and want to re-parent), open the expansion's Game info tab, change the Parent game field, and save. The relationship moves.
Tips & common questions
Can an expansion have its own expansions? Today expansions form a flat one-level relationship, base game with expansions, no nested expansions of expansions. For sub-expansion content, use components or notes within the parent expansion.
Can a game be marked as an expansion of multiple base games? Each game has one parent. For a "compatible with X and Y" relationship, pick one parent and mention the other in descriptions.
The dropdown for parent game is empty. You need at least one other game in your library to pick from. Create the base game first, then mark the expansion.
What if I converted a standalone game into an expansion? You can toggle Is expansion on at any time and pick the parent. Existing playtests, pitches, and other data on the game don't change.
Does the expansion inherit settings from the base game? No, each game (base or expansion) has its own independent fields, components, rules, and media. The relationship is purely organizational.
