Chess Clock
Set minutes per player and optional increment, then tap each player clock to hand the turn to the other side.
This is a casual local chess clock. If a competition uses a specific timing rule, verify the event rules and approved equipment.
Core timing workflows
Start with a direct timer, stopwatch, alarm or focus workflow. Calendar, date arithmetic, clocks and scheduling specialists remain available from the full Date & Time hub.

Timer Alarm System ·
Alarm sound & repeat
Immediate time-expired cue. The default is intentionally audible and repeats until you dismiss it.
Sound system loading…
WebToolArc can use the browser's full configured output level, but it cannot override a muted tab, muted device, system-volume limits, Bluetooth routing, browser background throttling or device sleep. Test the sound on the device you will actually use.
Game control
Presets, delay modes, move evidence and fullscreen
Add practical over-the-board controls while retaining the current two-player display and alarm system.

Presets update the existing minutes/increment inputs. Delay modes are handled by the overlay only when selected.
Practical guide and verification
Use the tool first, then use these checks to interpret, verify and hand off the result without turning explanatory content into the primary workflow.
Choose the timing rule before starting the game
Sudden death, Fischer increment, Bronstein delay and simple delay are different time controls. Set the mode, starting time and bonus/delay before the first move, and do not change them mid-game unless both players intentionally restart under a new control.
Use move counts and recent timing as a sanity check
A move counter helps verify that each clock press was registered and can reveal accidental double taps. If a game result matters, compare the move counts with the board record and note any pause or correction instead of silently editing the remaining time.
Test sound, fullscreen and keyboard controls on the actual device
Browsers can mute audio, throttle background tabs, reserve keyboard shortcuts, or behave differently in fullscreen. Before a serious practice session, test the exact laptop, tablet or phone setup and keep the screen awake where appropriate.
Treat the browser clock as practice equipment
The timer is useful for casual and training games, but formal events can specify approved equipment and exact delay/increment behavior. Use the event rules and arbiter guidance for competition timing rather than assuming a browser implementation is automatically tournament-approved.
