Number crossword with no questions. What the name?

[DCUK6]

Just remembering when I was younger I used to do a number crossword thing.

 

It gave you a load of numbers in groups depending on how many digits in the number and you had to fill the crossword like board in with them.

 

There wasnt any questions, just numbers that you had to fit in

 

Any ideas what these are called?
