What is a Word Fill-In?
A word fill-in (also called a Kriss-Kross) gives you a grid of empty boxes and a list of words. You must figure out where each word fits based on its letter count and where it must intersect with other words.
How to solve it
Start with the longest or most unusual words — they have fewer possible placements. Work outward from confirmed intersections. Every word in the list must be used exactly once.
Who is this for?
Fill-in puzzles appeal to fans of crosswords who want the logic challenge without needing to guess clue answers. Great for adults and older students who enjoy spatial reasoning.
