Space word search word list

47 words, hand-picked to fit a 15×15 grid. Free to use in any puzzle you make, including ones you sell. One thing to know if you build grids by hand: SUN sits inside URANUS — never put both in the same puzzle, or the shorter one is found twice. The generator keeps them apart automatically.

The button opens the free generator with this theme selected. It draws 15 words per puzzle and can make hundreds of different puzzles from this list without repeating a set — a 100-puzzle book comes to 124 pages at 6 × 9.

A puzzle made from it

Medium difficulty: across, down and diagonals, nothing backwards. Every word appears exactly once — the generator checks the finished grid rather than assuming. Solutions are in the book, not on this page.
