Fill in the grid using the 2-digit primes below it, one digit per box,
The 2-digit numbers are to be bounded by the heavy lines.
Navigate with the arrow keys, HOME, and END;
use the space bar to clear a square.
When used, the primes disappear from the list,
but are listed in parentheses ( ) if used more than once.
Non-prime values are prevented from entry.
