Padel Mexicano for 28 players

All 28 players play once in each complete round. Round 1 is random; the draw below is one example. From round 2, the standings form groups of four: 1st & 3rd v 2nd & 4th, then 5th & 7th v 6th & 8th, and so on. Partners and opponents can repeat.

8 players can play at once on 2 courts. On 2 courts, play the matches listed for courts 1–2 first, then 3–4, then 5–6, then 7. The other players wait between matches. With 7 courts, everyone could play at once in about 12 minutes. Finish the whole round before drawing the next one. Choose how many rounds to play; there is no fixed full schedule.
