- Equipment
- The game is played with a 36-card pack consisting of A-K-Q-J-10-9-8-7-6 in each suit, plus -
- 18 poker chips or large counters in three different colours, six of each colour; and
- nine cards from a separate pack, ideally old or incomplete, one each of A, 2, 3, 4, 5, 6, 7, 8, and Queen. The Queen represents zero (because "Q" resembles "0".)

- Set-up
- Arrange the nine odd cards in a 3 x 3 grid with the Queen in the middle. It doesn't matter
how the numerals are arranged - in fact, it's best that they differ randomly from deal to deal.
These are referred to as the scorecards.

Each player takes six counters of one colour.

Shuffle the playing pack and deal 12 cards each. - Object
- To get three of your counters

A critical position for all!**Yellow**wants 5

to win, or 0 to stop Red and possibly

Blue,or 2 to stop Red, or 7 to set up

two potential lines of three.**Red**wants

2 to win, or 1 to stop Blue and set up

two potential lines of three.**Blue**wants

0 or 1 to win, or 5 to stop both Yellow

and Red. If Yellow wins 5 and Blue 0,

both will have a line of three,

but Yellow will win by 12 to 7. If Red

wins 2 and Blue wins 1, both will have

a line of three, but Blue will win by 13 to 7. in any three-card row, column or diagonal of the scoreboard. At the end of each hand you place one of your counters on the scorecard corresponding to the number of tricks you took. - Trumps
- Establish a trump suit as follows. You each choose a card of the suit you propose
as trump and, when all are ready, reveal them simultaneously.
- If two or three are of the same suit then that suit is trump.
- If all three are different then the trump suit is the fourth one - that is, the suit that nobody chose.
- However, if any two are of the same
**rank**then the hand is played at**no trump**.

- Play
- The player at dealer's left leads any card to the first trick. You must follow suit if you can but may play any card if you can't. The trick is taken by the highest card of the suit led, or by the highest trump if any are played, and the winner of each trick leads to the next. If you win more than eight tricks, give each subsequent trick to either player of your choice, who then leads to the next.
- Score
- At end of play, you each place one of your counters on the scorecard representing the number
of tricks you won. However:
- If that card is already occupied by one of your own counters, do nothing.
- If it's occupied by an opponent's counter, return it to its owner and substitute one of your own.
- If two of you win the same number, and the appropriate scorecard is either blank or occupied by the third player, leave it unchanged.
- If the tricks divide four all, the winner of the last trick occupies the scorecard Four. (Or retains its occupancy, if already there.)

- Game
- You win a game by finishing with three counters in a row, whether horizontally, vertically or diagonally, after everyone has recorded their score. If two or all three players achieve this simultaneously, the winner is the player whose line of three cards has the highest total face value.
- Match
- A match is won by the first player to win two games in succession, or three games in all, whichever occurs first. Randomly rearrange the numerals A -8 for each new game.

Deal 13 cards each from a 52-card pack. Players sitting opposite each other are partners and may seek to cooperate with each other. Each partnership shares six counters of the same colour between them.

Fix trumps by each selecting a card and revealing them simultaneously. If two or three are of the same suit, that suit is trump - unless there are two each of two suits, in which case the hand is played at no trump, as it also is if all four are different.

Play as described above. Each partner places a counter of their colour on the scorecard corresponding to the number they took individually, so it is possible for two counters of the same colour to be placed at the end of the hand.

If both members of a partnership each win the same number of tricks and are already occupying the scorecard corresponding to that number, they must remove their counter from it.
