What Is a Pie in American Mahjong?

In some American mahjong groups, a “pie” is the fixed bank of points, chips, or monetary units assigned to each player at the start of a session. Wins and losses are transferred against that bank, allowing the table to track a running balance across multiple games.

The Pie Is a Table Convention

A pie is not a hand type and does not change the rules printed on the annual card. It is a bookkeeping framework used after a valid mahjong is declared and verified.

The group decides the starting amount, the value of each printed card amount, bonus treatment, and whether a player can continue after the original bank is exhausted.

How a Pie Session Works

  1. Set the starting bank

    Every player begins with the same agreed number of points or units.

  2. State the conversion

    Explain how card values, self-picks, jokerless hands, and discarder responsibility affect transfers.

  3. Record each game

    Subtract payments from losing players and add them to the winner's balance.

  4. Reconcile the totals

    After each game, confirm that all player balances still add to the original table total.

  5. Close the session

    Record final balances and settle them according to the group's stated practice.

Pie Rules to Decide in Advance

  • The starting bank for each player.
  • The point or payment value of each card amount.
  • Self-pick and jokerless adjustments.
  • Whether the discarder pays differently.
  • How wall games and penalties affect balances.
  • What happens when a player's bank reaches zero.

Pie Versus Simple Scorekeeping

Pie

Tracks transfers among fixed player balances and makes the table total a built-in accuracy check.

Simple Points

Adds points to winners without requiring losses to be deducted from a fixed bank.

Pie Questions

Does every American mahjong group use a pie?

No. Many groups keep simple points, use chips without a fixed bank, or do not score socially at all.

Can a pie use points instead of money?

Yes. The same framework works with purely fictional points or chips.

Why should the table total stay constant?

Because one player's gain should equal the combined losses recorded from the other players. A changed total usually signals a bookkeeping error.
