Letter tiles

Not here

Letters start gray and the cursor stays put, so you can colour one straight away with  /  or a click — the next letter you type moves along on its own. Gray not in the word · yellow in the word, wrong spot · green exactly here.
Not here rules a letter out of one slot without claiming it is in the word at all — for a letter that is gray in the crossing word.

Letter constraints

These count on top of the tiles. With one green S: also contains S asks for a second one; no more of S allows only that one. Click any letter above to cycle through both. Letters already settled by the tiles show dimmed.
