About this puzzle
Looking for a word search that actually makes you work? This one uses a 15×15 grid and hides long, less common words — think “kaleidoscope”, “juxtapose” and “ephemeral” — in all eight directions, including backwards.
It is a favorite for adults who find the usual puzzles too quick. Time yourself, then press New puzzle and try to beat it.
How to play
- Choose a level: Easy, Medium or Hard.
- Find a word from the list in the grid and drag across it — or tap its first letter, then its last letter.
- Found words are highlighted and crossed off. Clear the whole list to finish.
Tips
- Hunt for double letters (LL, SS, CC) and unusual pairs like “XY” or “JU” — they give long words away.
- Work one direction at a time: sweep all rows left-to-right, then right-to-left, then the diagonals.
- Cross words off as you go so your eyes skip letters you have already used.
