Shanghai Rummy variations are forms of contract rummy distinguished by their schedules of required melds, buying allowances, treatment of wild cards, and methods of finishing and scoring. The basic mechanism stays the same, drawing and discarding to form prescribed sets and suit sequences, but the rules governing those combinations differ between playing groups.
The name does not identify one universally observed ruleset. Seven-round, eight-round and ten-round forms are all described, alongside numerous house variations. Some keep the special Shanghai call; others drop it without changing the name of the game.
The seven-round version used throughout these guides is the reference for everything below. Rules taken from other versions are alternatives, not amendments you can drop into that game and expect to work. Settle the complete schedule before the first deal.
How the versions differ
| Rule | Seven-round reference version | Alternatives used in other versions |
|---|---|---|
| Number of rounds | 7 | 8 or 10 |
| Cards dealt | 11 every round | Often 10 or 11, according to the version |
| Cards received when buying | Wanted discard plus 2 stock cards | Wanted discard plus 1 stock card in some versions |
| Buying allowance | 2 per player per round | 3 or 4 in some versions |
| Aces in sequences | High only | High or low in some house rules |
| Going out | Final discard in rounds 1 to 6, none in round 7 | Some versions require every card to be played, with no final discard in any round |
| Shanghai call | Used | Omitted in some versions |
The alternatives in the last column do not together make up one coherent version. A group may adopt some and reject others, so whatever combination you land on has to be written down explicitly.
Round schedules
1. The seven-round version
The seven-round form opens with two sets of three and ends with three sequences played as the entire hand. It is a shorter schedule than the eight-round and ten-round alternatives while still covering sets, sequences and mixed contracts.
This is the version the rest of the guides follow. Its buying, joker, ace and scoring rules have to be kept together where those guides are used as a reference. Substitute one rule from another version and an example may stop being valid or stop being useful.

2. The ten-round version
Some versions extend the game to ten rounds. The opening four contracts resemble those of the shorter game, while later rounds introduce longer sequences and larger combinations.
For example, the eighth contract in one ten-round schedule requires a set of three and a sequence of ten. Those later requirements take longer to complete, so a ten-round schedule generally needs more playing time. Take the precise contracts from the schedule you have chosen rather than inferring them from the number of rounds.

3. The eight-round version
One eight-round variation deals ten cards to each player and puts four sets of three in as the seventh contract. The eighth and final contract then asks for three sequences of four.
Four sets need at least twelve cards. A player dealt ten cannot meet that from the original hand alone, so the buying rules become a structural part of that schedule rather than an optional extra. The cards obtainable through the permitted purchases have to be enough for the later contracts.

4. Alternative contract orders
The number of rounds does not by itself tell you the contract order. Different ten-round schedules may include a set of three with a sequence of seven, two sets of three with a sequence of five, or three sets of three with a sequence of five.
Read the complete schedule before play and keep it where everyone can see it. Similar opening contracts do not establish that the later requirements match another score sheet.

Jokers and buying
5. Play without jokers
Jokers may be left out by agreement. Every required combination then has to be formed from natural cards, and an internal gap in a sequence cannot be filled by a wild card. Long sequence contracts become correspondingly harder.
Consider the number of decks, the number of players and the buying allowance together when jokers come out. A group may decide to allow more buying, but that is a further house decision, not an automatic consequence.

6. Limits and replacement of jokers
The reference version allows no more than one joker in each set or sequence. Other tables allow more, and some forbid replacing a joker once it has been played.
The agreement covers both the number of jokers permitted in a meld and the treatment of an exposed one. Where replacing a sequence joker is allowed, the rules should state which natural card is required, when the exchange may be made, and whether the recovered joker must be used immediately. Those are separate questions from the initial limit.

7. One additional stock card when buying
In the reference version, an out-of-turn buyer takes the wanted discard and two stock cards, adding three cards to the hand. Other contract-rummy versions require only one additional stock card, adding two in total.
The difference changes what a useful discard costs. A smaller increase is easier to absorb; two additional stock cards leave more to dispose of. What that actually costs in points still depends on the cards received and the agreed scoring.

8. The buying allowance
The reference version permits two buys per player per round. One ten-round variation instead permits three in rounds one to eight and four in rounds nine and ten.
Coins, counters or written marks all work for tracking purchases. A larger allowance gives more chances at useful discards but can produce substantially larger hands. Record the number of buys and the number of stock cards taken with each buy separately.

9. Omission of the Shanghai call
Some versions leave out the Shanghai call entirely. Ordinary buying still works under the agreed rules, but a playable discard cannot be protected or claimed through the special procedure.
Dropping the call removes one thing to check before discarding. Exposed melds still matter, though, because they show where cards can be played and how a discard might help someone else.

10. High and low aces
The reference version treats aces as high only, so J-Q-K-A is a valid sequence and A-2-3-4 is not. Some related contract-rummy rules allow aces high or low, but none allow a sequence to wrap around the end of the rank order.
Under the high-or-low rule, A♠, 2♠, 3♠ and 4♠ is valid, while Q♠, K♠, A♠, 2♠ stays invalid. The low-ace option changes which cards can connect without making the sequence circular.

11. Going out without a discard
In one eight-round variation a player may not go out by discarding: every card must be played onto the table. That applies throughout the version, not only in the final round.
A leftover card with no legal destination can therefore prevent a finish even after the contract is complete. The rule governs going out; it does not stop ordinary discarding on turns when the hand is still unfinished.

12. Same-suit sequences
The reference version does not let adjoining same-suit sequences count as two separate parts of an initial contract. Other versions forbid more than one initial sequence in the same suit at all, while related games allow adjoining sequences outright.
So the agreement needs to distinguish adjoining sequences, sequences separated by a gap, and sequences whose rank ranges overlap. Whatever you decide about overlaps, one physical card can never occupy two melds at once.

Decisions for your table
Laying off and scoring
13. Laying off on a later turn
The reference version lets you lay off additional cards on the same turn as the initial contract. Under standard Contract Rummy rules, laying off waits until a later turn.
Same-turn laying off lets a player shrink the remaining hand immediately after exposing the contract. A delay leaves those cards in hand until the next opportunity. Settle this before anyone plans a turn that combines the initial meld with further additions.

14. A blind-out bonus
Some ten-round rules award a bonus for putting the complete hand down in one play, and a larger one where no joker is used. Since lower totals are better, the bonus is subtracted from the player's accumulated score.
This is not part of the reference version. A group adopting it records the exact amount and defines what counts as a qualifying blind finish, including how jokers are treated and which finishing procedure applies.

15. Alternative card values
The reference version counts two to seven at five points, eight to king at ten, aces at twenty and jokers at fifty. Other contract-rummy systems count numbered cards at face value, or give aces and jokers lower values.
These changes alter what an unplayed card costs to hold. A joker worth fifty is a much larger exposure than one worth fifteen. The difference is in the consequence of being caught with the card, not in what it can legally complete.
Keep the agreed values beside the score sheet and apply them consistently. Do not substitute a value from another rummy variant during scoring just because it is familiar to somebody.

16. Recording a house variation
A house variation can combine whatever the group wants, provided the complete rules are agreed before play. Write down the number of rounds, cards dealt, contract schedule, buying allowance, additional cards taken when buying, joker restrictions, ace position, same-suit sequence rules, Shanghai call, laying-off timing, finishing method and scoring.
Record any blind-out bonus with its conditions. Pay particular attention to whether the available cards and buying opportunities actually allow the later contracts to be completed.
Do not change rules once a round has begun. If a trial game shows a requirement is impractical, adjust before the next complete game.

Choosing a version
Consider the contract schedule and the special rules together. A shorter schedule suits a group with less time; extra rounds bring in further combinations and lengthen the game. Buying allowances, wild-card restrictions and finishing requirements all affect whether those combinations can actually be completed, and how the remaining cards are managed.
Agreement on the complete version is worth more than agreement on its name. A shared contract sheet and scoring reference settle which rules govern every deal. The cheat sheet covers the reference version if that is the one you pick.
Frequently asked questions
How many versions of Shanghai Rummy are there?
There is no fixed number. Seven-round, eight-round and ten-round descriptions coexist with house variations that change individual rules. Two games under the same name may differ in their contracts or special procedures.
Which version is a good starting point for beginners?
The seven-round reference version has a shorter schedule and introduces the main contract types over fewer rounds. A visible contract list and scoring sheet cut down how much has to be remembered while the basics are being learned.
May rules from different versions be combined?
Yes, by prior agreement. Record the result as one complete ruleset, including how the contract schedule, buying system and finishing requirements interact. Rules are not chosen retrospectively to settle a particular hand in someone's favour.
Is the Shanghai call used in every version?
No. Some versions omit it. The agreement should state whether a playable discard can be protected or claimed through that procedure, separately from the ordinary rules for taking or buying discards.
Do all versions use the same contracts?
No. Opening requirements are often similar, but later rounds can specify different combinations and sequence lengths. The schedule for the version you have chosen governs the game.
Play the seven-round version and see whether the schedule suits your group before you commit to a longer one.
