This is a criss cross
This puzzle was one of the puzzles we wrote to include in our wedding book.
To start, focus on words that have As and Js in weird patterns. For instance, JACINDA ARDERN has two As in a row and TAJ MAHAL has a lot of As and Js in a small amount of space. Whenever you put a word in the grid, fill in the boxes right in front of and right behind the words so you know that other letters cannot go in them.
