Your next match is waiting

Pick a level that gives you close, competitive matches. REFLEX League uses your requested level, your REFLEX match history, and your prior skill rating (where available) to confirm placement. If registration offers you a level that doesn't fit, contact us before the season starts so we can adjust it.

For Doubles and Mixed, your team level is based on both partners' ratings combined. We discourage pairings more than two full levels apart. Players who post an unusually high win rate in their first season may be moved up and can be held out of playoff contention if they were clearly under-rated.

Seniors (50+) leagues: Players who are 50 or older may register for Seniors Men's Singles, Seniors Women's Singles, Seniors Doubles, or Seniors Mixed by checking the eligibility box when building their profile. Seniors leagues use the same play levels and rules as our standard leagues — the difference is the age-based field. Seniors players remain free to enter any standard league as well.

Each match has a two-week window: a scheduled week and a built-in makeup week, ending on a "play-by" date. Reach out to your opponent early — by the Wednesday before the scheduled week — and each side should offer three workable dates within the league's normal days and times, or accept a date the other side offers.

If both teams offer three valid dates and still can't agree, the match defaults to the play-by date at the standard time. You may reschedule once with at least 24 hours' notice and confirmation from your opponent. Short-notice or repeat cancellations let your opponent claim a forfeit. If you can't reach an opponent at all after trying both phone and email, notify the league office and you may take the win by forfeit.

Late Pass: Each team gets one Late Pass per season. It lets you report a single match after its play-by date has passed — open that match on your schedule and choose “Use Late Pass to Report.” The Late Pass can’t be used on the final match of the season, and you only get one, so save it for when you really need it.

Standard tennis code-of-conduct guidelines apply, with REFLEX rules taking precedence where they differ. The home team supplies a fresh can of approved balls and covers any court or guest fees. Warm-ups run up to 10 minutes and aren't for practicing winners or serves.

• The home court must have working restrooms and, for evening matches, proper lighting — otherwise offer to play at your opponent's court.
• Coaching is not allowed, and spectators must stay off the court and never make calls or intervene.
• There's a 20-minute grace period for a late opponent before you may take a forfeit.
• Standard rest rules apply: up to 25 seconds between points, 90 seconds on changeovers, a 10-minute break before the third set, and one 3-minute injury timeout.
• Phones and smart watches stay muted during play.

Aggressive or abusive behavior is never tolerated and is grounds for default.

Matches are best two of three sets. If both teams agree before starting, a 7- or 10-point tiebreaker can stand in for a full third set — record that set as 7-6. The winning team posts the score by midnight of the play-by date, entering the actual set scores.

Points work like this: the match winner earns three points (one per set plus a bonus for the win, including forfeits and retirements). A losing team that wins a set earns one point. Unreported matches show as "not played" and score zero for both sides.

If conditions look doubtful, the home team must contact the away team by phone or text — never cancel by email, and never assume the other side already knows. If players have gathered and courts are wet, wait 30 minutes before calling it; if play has started, resume at the exact game and point.

For thunder or lightning, stop play and wait 30 minutes; a second strike means rescheduling. Matches above 95°F or below 32°F may be rescheduled at either side's request. Rained-out matches default to the play-by date unless both teams agree to play earlier or use a late pass.

Playoffs are opt-in — even division winners must opt in before the season ends. To qualify, you generally need at least {minPlayoffPoints} points and no more than {maxForfeitLosses} forfeit loss or unreported match. Teams are seeded by division finish, then total points, then game-winning percentage.

Each playoff round, offer two dates (weekends count in every league) or accept your opponent's. There are no late passes or extensions in the playoffs, and unplayed rounds advance no one. First-season teams with a 75%+ win rate aren't eligible for the bracket.

In a 7-point tiebreaker, the first to seven points wins, as long as they lead by two; if it reaches 6-all, play continues until someone is up by two. The first server delivers one point from the deuce court, then players alternate every two points, switching ends every six points.

In doubles, the serving rotation follows the same order used during the set, with each player serving two points in turn.

Temporary substitutes aren't allowed, but a permanent season replacement is. If a doubles partner is injured, you may bring in one permanent replacement (with their own REFLEX profile) rated at or below your team's level — though if you'd already played matches with the original partner, the team can't win the division or enter playoffs.

For singles injuries or any withdrawal, contact the league office right away. Note that there are no refunds or credits once schedules are posted.

The division winner is the team with the most points; ties are broken by game-winning percentage. Winners earn REFLEX League recognition and their result is recorded in the season history.

Finally, no one may video or record a match — or any part of it, including warmups — without consent from every player involved. If anyone declines and a team records anyway, the other side may walk away with the win.

Once you’ve completed your first season, the level you play in each following season is guided by how you did. REFLEX League looks at your game-winning percentage — the share of individual games you won across the season — together with any playoff finish. Here’s the ladder:
