This is a Table Tennis scoreboard that follows the current rules of the game!
Choose "best of" to say how many games should take place in the match.
Select "new game" to delete all scores and start a fresh game.
Click "swap ball" to choose which player starts with the service (also any time during the game if required). During the following games itself, the scoreboard changes service automatically.
After each game, a blue blinking arrow shows up to signal the change ends.
The blue blinking arrow will also show in the last game, once a player has reached 5 points.
The scores for each game (shown in the middle top section) are swapped after each game, same goes for "Sets won" and of course the orange Player A & B title.
This scoreboard also has a Deuce feature where it carries on scoring until there is a 2 points difference as per ITTF rules.

The rules say:
The winner of a game is the player to first reach 11 points with a difference of 2 points.
If the score is 10-10, the game goes to Deuce until one of the players has gained a lead of 2 points.

Remember to play a legal & good serve:
