CrosswordPuzzleLab.com is a free library of classroom crossword puzzles you can play right in the browser — or print for a worksheet in two clicks.
Crosswords are one of the sneakiest teaching tools ever invented: students think they're playing a game while they're actually practicing vocabulary, spelling, and recall. But finding a decent puzzle for YOUR topic usually means subscriptions or signup forms. We wanted puzzles that are simply... there. Pick a subject, play, print, teach.
Everything runs in your browser. Type answers straight into the grid, press Check to see what's right (green) and what needs another look (red), and completed clues cross themselves off. The Print button gives you a clean paper version for class.
No accounts, no sign-ups, no cost. The site is kept free by the small ads you may notice — that's the whole business model.
