Welcome to Number Fill-in puzzles book This is my second book with Number fill-ins and all puzzles in this book are new, previously unpublished.
Half of them are 15x15 in size and half are 16x16.
There are 80 puzzles in this book.
The entries are listed below the grid and it is up to you to find the way to fill them all in and complete the puzzle.
Hence, they are also known as Cross Numbers .
These puzzles are just like crosswords but with numbers.
