Choosing the right format

An overview of every format in Slams and when to pick which one, with a handy decision guide.

Running an Americano in Slams

In an Americano you switch partners and opponents every round. Slams forms the pairings, assigns the courts and keeps track of the individual standings.

Organizing a Mexicano in Slams

A Mexicano works like an Americano, but from round 2 onwards Slams pairs players based on the current standings, so the matches become more evenly matched as you go.

Mix Americano and Mix Mexicano

Two social formats where every pair always consists of one man and one woman. Slams automatically enforces the mixed pairing and an even split.

King of the Court in Slams

Here is how the King of the Court format works in Slams: fixed pairs, rotation across the courts toward the king's court, and scoring per court.

Beat the Box splits your participants into boxes of around eight players, with a round-robin and separate standings for each box.
