Basketball Scoreboard Features

• Basketball scoring: add 1, 2, or 3 points, subtract a point, or enter a custom adjustment.
• Game Clock: start, pause, and reset the countdown for the current period.
• Shot Clock: run it separately with full, alternate, pause, and clear controls.
• Game stage: move through the configured quarters, halves, or overtime periods explicitly.
• Team game state: track team fouls, remaining timeouts, and possession.
• Manual horn: sound the scoreboard horn or buzzer when browser audio is supported.
• Undo and Redo: reverse or restore previous scoreboard changes.
• Fullscreen display: show only the read-only scoreboard on the current device.

Game Clock and Shot Clock

Run the Game Clock for the current period while controlling the Shot Clock separately. You can start, pause, and reset the Game Clock, then use the Shot Clock's full or alternate reset, start, pause, and clear controls when the chosen format enables it. A score change never starts, stops, or resets either Clock.

Basketball Formats and Rules

Choose from seven setup choices: Custom, NBA-style, FIBA-style, NCAA Men-style, NCAA Women-style, NFHS-style, or Youth-style. That is six rules presets plus Custom. Depending on the choice, games can use quarters or halves, configured overtime periods, timeout and foul settings, and enabled Shot Clock values. These profiles describe scoreboard behavior and do not imply league or governing-body affiliation, certification, or endorsement.

Undo, Local Saving, and Recovery

Undo and Redo restore score, period, foul, timeout, possession, clock, and team changes. The current game and its recent changes are saved in this browser when browser storage is available, so a reload can restore the board. Clearing site data can remove that local game. Reset is undoable; New Game removes the saved game and returns to setup.

What This Scoreboard Does Not Do

This is a user-controlled basketball scoreboard, not a professional live-score feed or an official scorer. It does not automatically start overtime, make referee decisions, manage a league or tournament, or track player statistics. Remote control, public viewer links, OBS overlays, cloud backup, and cross-device synchronization are not included.
