Online Scoreboard

A scoreboard sized to the screen it is shown on: two teams, numbers that read from the far end of a gym, and a full screen button for the TV or the projector. You set the point buttons, so a basketball board has 1, 2 and 3 and a card game has one, and every press is undoable through the whole session, up to two hundred changes back. The clock counts up or down and is worked out from the timestamps of the presses rather than counted frame by frame, so a tab left in the background or a phone that locks does not leave it drifting behind the game. The keyboard scores without touching the mouse, and it stays out of the way while you are typing a team name, which is the mistake most score counters make. Nothing here is uploaded and there is no account: the board is kept in this browser, and it is not synced to any other screen.

Clock

The point buttons are yours to set: 1, 2, 3 for basketball, 1 for most things, 3, 5, 7 for a sport that scores that way. Up to six, separated by commas. Period length takes minutes (12) or minutes and seconds (12:00).

Nil all. Score with the buttons under each team, or with the number keys once the board is on screen.

Keyboard

  • 1 to 6score for the home team with that button
  • Shift and 1 to 6score for the away team
  • Zundo the last change
  • Sstart or stop the clock
  • Pnext period, with Shift for the one before
  • Ffull screen

The shortcuts work while the board is on screen, and never while you are typing in a field: a digit typed into a team name is part of the name, not a point.

Read from the clock, not counted. The time is worked out from the timestamp the clock was started at, so a tab in the background, a locked phone or a slow browser cannot make it drift: the first reading after the page wakes is the right one. Count down and the clock stops at zero rather than going negative.
Accuracy. The clock measures elapsed time from your device's own timestamps, so it stays correct while the tab is in the background. Scores, names and time are what you enter on this device: nothing is synced to another screen, and closing the tab without the saved board is the end of it. Undo steps back through the scores, the periods and a reset, up to two hundred changes. The board is remembered in this browser alone, with the clock stopped at the time it showed.

Common questions

How do I show the scoreboard on a TV or a projector?
Connect the screen the way you normally would, open this page on the machine driving it, and press Full screen under the scores or the F key. The board then fills the display and the numbers scale with it, so a score is readable from across a hall. If a browser refuses full screen, which happens inside some embedded frames, the board falls back to filling the window instead and says so; press Escape to come back. Keeping the laptop screen mirrored means you can score from the same board the room is watching.
What are the keyboard shortcuts?
The number keys 1 to 6 score for the home team using the point buttons you have set, so on the default board 1 adds one point, 2 adds two and 3 adds three. Hold Shift with the same number to score for the away team. Z undoes the last change, S starts or stops the clock, P moves to the next period and Shift with P goes back one, and F is full screen. They work while the board is on screen, and they are ignored completely while the cursor is in a text field: typing a digit into a team name types the digit rather than scoring a point.
Can two devices show the same board?
No. This board runs entirely in the page you have open, with no account and no server behind it, so there is nothing to keep a second device in step and none is claimed. One device scores and any screen mirroring that device shows the same board, which covers the projector and the TV case. If you need a referee's phone and a hall display to update each other over a network, this is not that tool.
Does the score survive a refresh?
Yes. The scores, team names, colours, period, point buttons and clock settings are saved in this browser, so a reload or a closed tab opens on the board you left. The clock comes back stopped at the time it was showing rather than counting the minutes the tab was closed, because those minutes were not part of the game. Start over in the row above the heading clears it. Nothing is stored anywhere but this browser.
Can I change what a point is worth?
Yes, that is what the Point buttons field is for. Type the values you want, separated by commas, up to six of them: 1, 2, 3 for basketball, a single 1 for most card and board games, 3, 5, 7 for a sport that scores that way. The buttons under each team change as you type, and the number keys follow them, so key 2 always presses the second button. A minus button sits beside them for the point that was counted twice.
Does the clock count up or down?
Either. Count up runs from zero, which suits a game with no fixed period. Count down starts from the period length you enter, as minutes (12) or as minutes and seconds (12:00), and stops at zero rather than running negative. Both are read from timestamps, so the clock is not thrown off by a background tab, a locked phone or a browser that throttles its timers. There is also a No clock setting for a board that only keeps score.
What does undo cover?
Every score, every period change and a reset, two hundred changes deep. Press Z or the Undo button and the scores and the period go back to where they stood before the last press, so a point given to the wrong team costs one keystroke to fix. A reset asks for a second press before it clears anything, and even then undo brings the scores back. Renaming a team or changing a colour is not on the stack and is never put back by an undo, because retyping a name would bury the scoring under every keystroke.
