Online Scoreboard

How to Use This Online Scoreboard

Keeping score with pen and paper during a pickup basketball game or gym-class relay gets messy fast—someone always loses track after a timeout, and rewriting numbers on a whiteboard wastes play time. In my experience coaching youth leagues, the sideline argument is never about the rules—it is about whether the score was 14 or 16 after a chaotic sequence under the basket.

This board keeps two team names, two scores, and one countdown clock in a single view so you can tap +1 or −1 without doing mental math on the sideline. To get started, rename Home and Guest to your team labels, set Minutes for the period length, click Reset on the timer to load that duration, then use Start and Pause during the game.

• Update scores with +1 when a team scores and −1 to correct a mis-tap. Scores never drop below zero.
• Run the clock with Start, Pause, and Reset. Enter whole minutes from 1 to 120, then Reset while paused to apply a new game length.
• Open Fullscreen when you want the numbers readable from across a court, gym, or classroom projector.
• Reset all clears names, scores, and the timer when a new match begins.

Think of the clock like a kitchen timer tied to a score sheet: you pick a length, run it down, and adjust points as plays happen. The timer does not add bonus time on its own—you reset it when a new half or quarter begins. Your names, scores, and clock value stay in browser storage until you click Reset all or clear site data.

Moving onto practical environments: gym teachers run 10-minute relay heats; rec-league parents track pickup games on a phone in fullscreen; office trivia nights rename teams after departments. The layout stacks on narrow screens and buttons are sized for touch—open the same URL on a tablet propped on a bleacher. Team names accept up to 20 characters—enough for "Blue Team," a class period label, or abbreviated club names without truncation on most phones.

The scoreboard does not whistle when time expires—it simply stops at 00:00 so you can call the period yourself. That keeps the tool flexible for sports with running clocks, informal countdowns, and classroom activities where the buzzer is your voice. If you need a fresh match, Reset all wipes names back to Home and Guest alongside scores and the timer—use it between games rather than mid-period unless you intentionally want a clean slate.

Scores persist in local storage on the same browser and device. Opening the URL on a second phone starts a separate board—there is no live sync between devices. For a shared view, mirror one phone to a TV or projector and let one person operate the buttons.

Online Scoreboard Formulas and Practical Applications

The countdown display converts your minute input into seconds and subtracts elapsed time each second the clock runs.

Step 1: Initial duration

Total Seconds = Minutes × 60

Step 2: Remaining time

Remaining Seconds = Total Seconds − Elapsed Seconds

Example: with 10 minutes loaded, the display starts at 10:00 (600 seconds). After 2 minutes of running time, 600 − 120 = 480 seconds remain, shown as 08:00 in MM:SS format.

Each +1 button adds one point to that side. The −1 button removes one point but never drops below zero—handy when you mis-tap during a fast break and need a quick correction without resetting the whole board. During timeouts you can Pause the clock without losing the remaining time display; Reset on the timer reloads the minute field value while scores stay intact until you change them manually.

Fullscreen hides browser chrome so players see only the clock and scores—exit with Esc on most browsers. If the timer and scores disagree with what happened on court, −1 corrects a single mis-tap faster than resetting the entire board mid-game.
