FAQ

You can sign up in either of the following two ways:

• Sign up with email and password: Click the link in the confirmation email you receive after signing up to complete registration
• Sign up with a Google account: Just select your Google account from the "Sign up with Google" button on the sign-up screen to complete registration (no confirmation email needed)

You don't need to set a password. You'll also use Google authentication to log in.
If you want to set a password later, you can do so from "Click here to set a password" on the account edit screen in My Page. Once set, you can also log in with your email and password.

Yes. If you log in with Google using a Google account that has the same email address as your registered account, it will automatically link to your existing account.
After linking, you can log in either with your email and password or with Google authentication.

Invite the player you want to register from "Player management" in the menu. Signing up via the invitation link carries over their recorded stats to the new account.

Add them from "Invite a Janreco user" on the add player screen.
This links to their Janreco account, so they can also view their stats from their own account.

That's fine. However, we recommend using different player names to avoid confusion when selecting players.

Yes, you can delete it from the edit screen in "Player management" in the menu.

Yes, you can change the name from the edit button in "Player management" in the menu.

When scores are tied, points are calculated according to the rule's "Tie-break" setting.

Float-based is a rank point method used in the official rules of the Japan Professional Mahjong League (JPML). Unlike the usual fixed rank points, rank points automatically change based on the number of players whose score is at or above the return points at the end of the game (players above return).


* If all four players are above return, or all four are below it, everyone gets 0 rank points.

On the rule creation screen, switch "Rank point mode" to "Float-based", or tap the "JPML official rules" template to fill it in automatically.

Selecting float-based automatically sets the following items.

• Decimal rounding method → fixed to "Keep decimals"
• Tie-break → fixed to "Split evenly"
• Only supported for four-player mahjong (not selectable for three-player mahjong)

No, it isn't. Please adjust the points manually.

Yes. Including byes, you can select 4 to 12 players for four-player mahjong, and 3 to 12 players for three-player mahjong.

In pt entry mode, rank is determined from the entered pt, and the score is calculated automatically.
- With the "Keep decimals" rule, scores are calculated in units of 100 points.
- With any other rule, scores are calculated in units of 1,000 points. Note that if you enter a score first and then turn on pt entry mode, the score may change as a result.

Turn on "Yakitori tracking" in the settings on My Page, and a yakitori checkbox will appear on the match entry form.
Check the box for any player who got yakitori and save — you can then view yakitori records and stats on the match details and stats pages.
* This is a Pro plan exclusive feature.

Yes. Turn off "Seat recording" in the settings on My Page, and you will no longer need to pick seats on the match entry form. For league matches, the league's "Seat recording" setting (on the league create/edit page) takes priority over your personal setting.
In matches recorded without seats, ties are kept as shared ranks and rank points are split, instead of being broken by seat order. These matches are also excluded from seat stats in your overall and league stats, and from seat-based league titles (East seat, etc.).
* Changing the setting later does not change whether seats were recorded for matches already saved.

Go to "League list" in the menu, select the league you want to edit to open its detail screen, then edit it from the "Settings" button.

Go to "League list" in the menu, select the league you want to delete to open its detail screen, then delete it from the "Settings" button.

Unlike an individual league, a team league is a league format where teams compete based on their combined stats.
The sum of each team member's match points becomes the team's score, and teams compete on the team standings.
Team-league-specific analysis features let you check things like each team's stats trend and each member's contribution.

On the team settings screen, you can configure the following:

• Team name and team color
• Team logo and team description
• Member assignment (chosen from league participants)
• Ghost player and scorekeeper settings

Using the bulk team edit screen, you can edit every team's name, color, logo, and description at once.

A team can be deleted if the following conditions are met:

• No team member has any match records
• The number of teams after deletion does not fall below the minimum number of teams (based on the mahjong type)

You can delete a team from the team edit screen or the team settings screen (bulk edit).

A member can only be removed from a team if they have no match records.
If you want to remove a member who has match results, please delete those results first.

Yes, on the Free plan, up to 50 players can join a single league.
With the Pro plan, up to 100 players can join. Since this is determined by the league organizer's plan, participants' own plans don't matter as long as the organizer is on the Pro plan.

Yes, up to 20 teams per league (the same for both Free and Pro plans). There is no limit on the number of members per team.

A ghost player can take part in matches but does not appear on the standings or stats charts.
Use this when you want someone to join as a fill-in or helper without including them in the league's ranking competition.
This can be set in both individual and team leagues.

A scorekeeper is a member who doesn't take part in matches and only records match results (score entry).
This can only be set in team leagues, and requires a Janreco account.

A ghost player can take part in matches but doesn't appear in the stats. A scorekeeper doesn't take part in matches and only records results.
Neither appears on the standings or stats charts.

Role	Plays in matches	Standings / titles	Records matches *
Regular member	⚪︎	⚪︎	⚪︎
Ghost player	⚪︎	×	⚪︎
Scorekeeper	×	×	⚪︎

* A Janreco account is required to record matches

A player with no match records can be switched between regular member, ghost player, and scorekeeper at any time.
A player with existing match records cannot be changed.

Neither a ghost player nor a scorekeeper can belong to a team. Only regular members can belong to a team.

You can import results in bulk from a CSV file or pasted text via "Bulk import results" in the league menu. The columns are Game No, Date, Seat (only for leagues that record seats), Player and pt, and you can download a template from that page.

"Bulk import results" appears only when all of the following are met.

• You are the league organizer
• For team leagues, the teams have been created
• "Include chip pt in league stats" is turned off (leagues that include chip pt can't use this feature, for both 3P and 4P)

Importing and registering results requires the organizer to be on the Pro plan.
