Check the player before the number
The easiest error to miss is a correct visit entered for the wrong player. Before submitting, check the highlighted name and that player’s remaining score. This matters particularly when a match uses a bot, when a marker changes during the game, or when several people are looking at different screens.
Enter the visit total once
A normal score-entry box expects the total of up to three darts. Treble 20, single 20 and single 5 make 85, not three separate score submissions. Press Enter once and wait for the saved turn to appear before entering the next visit. If the connection is slow, repeated submissions should not be your way of checking whether the first score worked.
A bust cancels the whole visit
Starting on 32, single 20 leaves 12; single 13 then takes the running total below zero. The visit is bust and the remaining score returns to 32. Leaving exactly 1 in a double-out game is also bust. Reaching zero with a single instead of the required double does not win the leg.
Use the Bust control for an invalid visit. A normal zero visit can represent three darts that scored nothing without breaking the finishing rules. The score contribution may be zero in both cases, but the recorded explanation is different.
Count only checkout darts actually thrown
When a player checks out, the winning visit can use one, two or three darts. If the first dart misses double 16 and the second hits it, enter two darts used. Do not count the unthrown third dart. A visit total cannot reliably tell the system how many darts were used, which is why the scorer asks.
Correct the last visit promptly
If the wrong score has just been saved, use Undo before continuing. Confirm that both the remaining total and throwing player return to the expected state, then enter the correction. If another scorer is controlling the same game, agree who will make the change so you do not both try to repair it.
Keep live and read-only links distinct
Share a stats or public result link with spectators. Keep score-entry permissions, scorer PINs and private remote invitations with the people who need to operate the match. A spectator should not need a scoring password to read a finished public result.
Recognise a connection problem
A frozen remaining score is not evidence that the previous visit failed. Check the status message and the latest saved visit before retrying. Keep the page open if an entry is still saving. If you need help, note the match number and the time of the problem; do not send a password or private invitation in a support message.
Before starting the next leg
Check the leg winner, match score and starting player. Best of five means first to three legs, so the match may finish 3–0 or 3–1. Agree the format before the first dart and follow the competition’s published rules where they differ from a general pub-game guide.
