THE SHORT ANSWER

A joker, a blank and a spare serve different purposes. Label each category in the inventory and packaging; an extra tile in a retail box is not automatically permission to use it in the group’s game.

Give every supplied tile a purpose

The most useful contents list includes the identity, quantity and purpose of every tile. “Extra pieces included” is insufficient when a buyer needs to know which pieces belong in normal play. Assign each line to playing inventory, spare inventory or an explicitly agreed optional item. This small documentation step makes sampling, packing and customer support much easier to compare.

Explain joker use without reproducing the card

Yellow Mountain Imports’ published guide distinguishes joker use in groups of three or more identical tiles from singles and pairs. It also separates the standard playing inventory from extras in its own retail set. Detailed situations should be checked against the chosen rules reference. A product manufacturer should not turn a simplified insert into a claim that it is an official ruling service.

Separate house rules from standard descriptions

A group may choose its own convention for an extra tile. That is a table agreement, not a feature that changes every set sold under the American mahjong name. In a public discussion about thick tiles, players also debated what to remove from a larger retail inventory. The purchasing implication is straightforward: organize extras separately and make their role visible before the first game.

Plan replacements before a problem occurs

A spare is most useful when its back, profile and finish match the collection. A public buyer discussion described jokers that differed physically from other tiles; this is an individual report, not evidence of a brand-wide defect rate. For a custom order, compare repeated pieces in the actual sample and discuss whether an agreed spare allocation should be packed with the original batch.

Build an inventory worksheet that survives handover

Keep an approved tile list with the artwork version and packaging layout. The designer, supplier and person checking the shipment should all use the same schedule. Counting a carton total alone will not reveal a repeated face replacing a missing one. A practical inspection lays tiles into identity groups and reconciles each group with the specification before signing off.

Prepare a clear response to missing pieces

Ask the supplier how to report an issue, what evidence is needed and what replacement arrangements apply. Our reporting deadlines, required evidence and replacement handling are confirmed by inquiry; no universal free-replacement promise is published. Keep the order reference and identify the exact missing or affected face. Clear photographs can support a conversation, but an agreed procedure is still necessary.

Help the retailer explain the box

Photograph the playing inventory and extras separately, and keep the product listing consistent with the packed sample. Avoid borrowing another brand’s 160- or 166-piece formula. If the set changes, update both the contents list and customer-support reference. A familiar total number is useful for orientation, but the itemized list remains the controlling procurement document.
