Keep score, tile by tile
Tap a name to change it. Add player puts a third or fourth on the board; the × next to a name removes them. Names stick around between games.
Type the word played. Tiles appear on the rack with their values, and the running total sits above the Add button. Tap Add to give those points to whoever's turn it is — play then passes to the next player automatically.
Tap a tile to cycle it: double letter, triple letter, blank, plain. Use Double word or Triple word for the whole play, and tap either twice if the word covers two of those squares.
Used all 7 stays greyed out until the word reaches seven letters, since a shorter word can't have emptied your rack. Above that it's your call — a long word that hooks onto tiles already on the board might use only five or six of yours, and the app can't tell. Shorten the word after setting it and the bonus comes off automatically.
Switch to Number if you've already done the maths. Negative numbers work here, which is what you want for the end-of-game deduction for tiles left on a rack.
Undo last turn reverses the most recent score and hands the turn back. To remove any other turn — or a word that was successfully challenged — tap the × beside it in the Turns list. That takes the points off without giving the turn back.
Tap any player's row. The gold marker moves to them and the Add button follows.
Finish game shows you the winner, files the result under Past games, and clears the board for the next one. Clear wipes the scores without saving. Everything is stored on this device in this browser, so it survives closing the page.
Tap a tile to mark it: double letter, triple letter, blank. Word check uses a general English dictionary, not a tournament word list.
A double or triple square scores only on the turn its tile is laid. Later words running through that tile take it at face value.
The star is a double-word square, so the opening play is always worth twice its letters.
Lay one tile alongside an existing word and you score each new word formed. The tile counts in all of them, and a premium underneath it applies to each — a double-word square doubles both words through it.
