Questions
Which letters are used?
Each puzzle uses the nine letters of one everyday word with no repeated letters, like BIRTHDAYS, CHIPMUNKS or BLUEPRINT. The word is shown above the grid.
Could a row spell something rude?
No. Every grid is checked so that no row, column or box spells an unkind word, forwards or backwards.
