The normal goal of the puzzle generator is to make puzzles with as much overlap as possible, in order to make the puzzle as challenging as possible.

Some audiences find this too difficult. So this option gives you the choice of which directions words are placed.

• Allow all directions.
  This builds a normal wordsearch puzzle.
• Allow only forward and down.
  This restricts the words to only going from left to right, or up to down.
• Allow only forward and down, don't cross words.
  This is like the above, except that the words aren't allowed to cross. They can touch. This is for even simpler puzzles.
• Allow only forward/back and down/up.
  This doesn't allow diagonals.
• Allow only diagonals.
  This only allows diagonals. Use this every now and then to throw frequent users off.
• Allow only reverse directions.
  This is another one to distract frequent users. Note that reverse on diagonals is a little arbitrary.
