Squash scoreboard.

Squash games at PAR 11 are short and brutal. A point is decided every 30 seconds. By the second game, the marker on the bench has lost track of who is serving from which box and whether anyone is "match ball". A digital scoreboard takes that load off — and projects giant numbers the gallery can actually read.

• — Open /play?sport=squash on a phone or tablet.
• — Tap left or right to award the point. The serve indicator updates automatically.
• — PAR 11, win by 2 is the default. You can switch to sudden death (first to 11) for casual play.
• — Best of 5 games is enforced — match score updates as games close.
• — Cast to a TV in the gallery for a club tournament look on a £40 budget.

• — Game: PAR 11 — points-a-rally, first to 11, must win by 2. (PSA pro tour standard since 2008.)
• — Match: best of 5 games. First to 3 games wins.
• — Sudden death option: at 10-10, you can toggle to "first to 11 wins outright" for casual matches that need to finish on the clock.
• — Serving: in PAR scoring you only switch sides when the rally is won by the receiver. The scoreboard shows which side the next serve comes from.

If you grew up on the old "hand-in, hand-out" scoring (HiHo, 9-point games), read the rules guide to see how PAR 11 changed everything.

The cheapest way to run a club tournament with a real-looking scoreboard: an old iPad in the gallery, AirPlay-mirrored to a wall-mounted TV, RallyRef in fullscreen. You get giant readable numerals, an authoritative serve indicator, and a match score the players can glance at between rallies. Total cost: nothing.

For league nights with multiple courts running at once, open RallyRef in multiple browser tabs — one per court — and keep them on separate displays.
