What is Crossword?
Crossword is a quick way to review terms, vocabulary or key concepts as a game. You type the answer words and a clue for each - or let AI draft a full set from a topic - and Verbalu packs them into an interlocking grid automatically.
Share the puzzle by link or QR code and players solve it on any device, reading the clues and filling the grid square by square. Answers are checked as they go, so they know the moment the whole crossword is solved.
