Questions

How many clues does this Ocean crossword have?
8 across and 7 down, on a 15 x 16 grid. The longest answer is STARFISH (8 letters).
How do I switch between across and down?
Tap a square to type into it, and tap the same square again to turn the corner. The answer you are filling is shaded on the grid and its clue lights up in the list, so you always know which one you are on.
Will it tell me when a letter is wrong?
Only when you ask. Press Check letters and any wrong letter is marked. A crossword is solved by reasoning across two answers at once, and flagging a letter the moment it is typed takes that away.
Can I print this crossword?
Yes. The printable version carries the same grid and clues with the answer key, at three difficulties.
