The ranking creates the pairingsWithin a group of four, rank 1 partners rank 4 against ranks 2 and 3. The next group of four follows.

Mexicano works like Americano with one decisive difference: the pairings are not set in advance but recalculated after every round, based on the current standings.

After the first round there is a provisional ranking. For round two the players are sorted by it: the leader plays with the fourth against the second and third. The next four form the second match, and so on.

The effect: play well and you face increasingly strong opponents. Struggle and you end up with people at a similar level. Matches get closer over the evening rather than drifting apart.

Because every round depends on the results of the previous one, a Mexicano cannot be printed in advance. The schedule emerges while you play — that is the price of the better mixing.

A round worked through

Eight people, one court, playing to 21. Here is how round two comes out of round one.

After round 1 the table looks like this:

Round 2 is built from it. The top four play each other, the next four likewise, following the pattern first and fourth against second and third:

The leader gets the weakest of the top group as a partner, which balances things within the group. At the same time positions 1 to 4 only meet each other, as do positions 5 to 8. Over several rounds this produces two to four ability groups in which matches become noticeably closer.

With a single court the groups simply play one after the other. The effect is the same, the evening just takes twice as long. With two courts both matches run at once — the usual setup for eight people.

Frequently asked

Can you switch from Americano to Mexicano mid-tournament?
Not sensibly. Both count the same way, but the pairings already played do not fit the Mexicano logic. A fresh run is better.
How many rounds make sense?
At least six, so the table can settle. With fewer rounds an unlucky first round weighs too heavily.
Can you see the standings during play?
Yes. The ranking updates as soon as a result is entered — it is also the basis for the next round.
Does Mexicano work with an odd number of players?
Yes, a corresponding number of people sit out each round. What matters is that byes are spread evenly.
Does Mexicano work with four players?
You can start with four — but the ranking-based pairing only really pays off from eight players, once two or more ability groups form and matches get closer within them. With four or six players Americano is the better pick: everyone plays with everyone instead of the standings locking in the same pairings.
