Cross Play — play through a letter on the board

Your best word often isn't on your rack — it's the one that plays through a letter already on the board. Enter your tiles, then a pattern: the board letter(s) typed in place, a . for each open slot the word fills from your rack. The word may extend past the pattern on either side unless you pin an end.

Your tiles (letters, ? for a blank)

Pattern (board letter in place, . = open slot) — e.g. .A. crosses an A Premium squares on the open slots (tap to cycle: DL, TL, DW, TW) — they only ever apply to tiles you play this turn, never to the board letter

Word must start at the pattern Word must end at the pattern

How scoring works here

Board letters (blue tiles in the results) count at face value and use none of your rack.
Premium squares apply only to rack tiles you place on them this turn — exactly like a real board.
A letter played from a blank tile scores 0, premium or not, and shows purple.
Emptying a full 7-tile rack through the cross is still a bingo: +50 (Scrabble) or +35 (WWF), included and labeled.
