Inviting Players: Invite Codes and Joining a League

Every league on Nerd Leagues has a unique invite code. There are three ways to get someone into your league, and three ways they can join.

Your League's Invite Code

When you create a league, Nerd Leagues generates an invite code that pairs an iconic Magic card name with four digits — lightning-bolt-4729, sol-ring-1156. It's short enough to read out over voice chat, and with a curated card list and 9,000 suffixes per card it isn't guessable.

To find your league's invite code:

1. Open your league page (from My Stats → click the league card).
2. Scroll to the League Info panel in the sidebar.
3. The invite code is displayed there as a clickable link.

Any league member can see and share the code — it isn't commissioner-only.

Changing the Invite Code

Only the commissioner can change the code. From the league page, click Manage League, edit the Invite Code field, and save. The new code only allows lowercase letters, numbers, and hyphens.

The replacement can be anything URL-safe — tuesday-cedh, shop-league-2026.

Three Ways to Invite Players

1. Share the Join Link

The invite code on your league page is itself a clickable link to /join_league/<your-code>. Right-click → copy the link and paste it into Discord, iMessage, email, wherever. Anyone who clicks it (and signs in) joins automatically.

2. Share Just the Code

If you'd rather pass around a short string, give friends just the code. They can paste it into the Join League form on their own My Stats page (covered below).

3. Send an In-App Invite

If your friend already has a Nerd Leagues account, you can invite them directly:

1. Open the league page.
2. Click the Invite Friend button in the league header.
3. Search for the player by username.
4. Click Invite next to their name.

They'll get an in-app notification, and a "You've been invited" banner appears at the top of your league's page when they visit it. By default, any league member can send these invites — the commissioner can lock that down (see below).

The system prevents duplicate invites: if a player already has an unread invite to your league, the button will report "Invite already sent" instead of stacking notifications.

Three Ways to Join a League

1. Click a Join Link

Click any /join_league/<code> link. If you're signed in, you're added to the league instantly and redirected to the league page. If you're not signed in, you'll be prompted to log in first.

2. Enter a Code on My Stats

1. From the top navigation, click My Stats.
2. In your leagues grid, click the Join or Create a League tile.
3. Paste the league code into the League Code field and click Join League.

This takes you straight to the join URL, same as clicking a link.

3. Accept an In-App Invite

If a league member sent you an invite, you'll see a notification in your bell icon at the top of the page. Click it. You'll land on the league's page with a banner that says "You've been invited". Click Join League in that banner to confirm.

Open vs Locked-Down Invites

The commissioner controls whether non-commissioner members can send in-app invites. In Manage League, the Member Invites checkbox toggles this:

• Checked (default): Any member can use the Invite Friend button.
• Unchecked: Only the commissioner sees the Invite Friend button.

This setting only affects the in-app invite button. The invite code link still works for anyone who has it, regardless of the toggle — so the code is what actually controls who can join. Public vs Private Leagues covers the layers in full.

What's Next

Once your league has members, the next steps are:

• Register your decks so each one tracks its own per-league ELO — see Adding Decks to a League.
• Record your first game and watch the league standings populate — see Recording a League Game.
• Plan a season if you want a time-bounded competitive window — see Creating and Managing Seasons.
