A crossword without clues
A fill-in puzzle (also called kriss-kross or word fit) gives you the grid and the answers, but not where they go. The word bank is grouped by length, and solvers work out where each word fits by counting squares and checking where letters cross. It's a puzzle-book favourite because it's satisfying without needing general knowledge.
Because there are no clues, it's quick to make: just type the words. That makes it a handy way to review vocabulary or spelling. The puzzle is only solvable if the words really interlock, so the generator builds the grid with the same careful engine as our crossword maker.
If the list won’t pack, we say so
Fill-in puzzles must use every word on the list. If a word cannot be fitted, usually because it shares no letters with the others, you will see a clear message naming it, and printing is disabled until it is fixed. Press New layout to try another arrangement, choose a larger grid, or swap the word. We never print a puzzle that leaves a word out without telling you.
Tips
- 12–25 words is the sweet spot. Several words of the same length make it more interesting.
- Turn on the starter word to fill in the longest word for the solver, a classic way to get started.
- The answer key shows the completed grid on its own page.
Questions people ask
What is a kriss-kross puzzle?
A grid where you fit a given list of words into interlocking spaces. There are no clues, just the word list grouped by length.
What happens if my words don’t fit together?
The generator names any word it couldn’t interlock and won’t print an incomplete puzzle. Try New layout, a bigger grid, or add words with common letters.
Is there a starter word?
Yes, optionally. The longest word is filled in and crossed off the list to help solvers begin.
How is this different from the crossword maker?
Same grid engine, but no clues. Solvers place words by length and crossing letters instead of answering clues.
Does it print an answer key?
Yes, the completed grid prints as a separate page.
