FAQ: Solving

How do I write my answers?
You can bring up the keyboard by pressing the pencil button in the upper right corner, or by double-tapping anywhere in the grid.

How do I switch directions in the grid?
Tapping once on the active (dark gray) square will always switch directions. You can choose additional ways of switching directions in the Settings menu. Possibilities include: tapping anywhere in the active clue, tapping a numbered square, and tapping or double-tapping the clue bar. See the Settings FAQ for more information.

How can I check if my answers are right?
Press the white check mark in the upper-right corner to bring up the check menu. You can choose to check or reveal a single square, a whole clue, or the entire grid.

I don't see a white check mark in the upper-right corner.
Then you must have disabled cheating in the Settings menu. If you set "Allow Cheating" to OFF, the white check mark will no longer appear. Turn this option back on if you want to be able to check your answers.

I somehow managed to type more than one letter into a square. What's going on?
You must have triggered “multiple-letter mode” by double-tapping in a square when the keyboard was up. You can tell you're in this mode because the active square is highlighted in white.

Why would I ever want to type more than one letter into a single grid square?
Some tricky puzzles have solutions that require this. (See, for example, the New York Times puzzle from February 14, 2008.)

I keep triggering multiple-letter mode accidentally. Is there a way to disable it?
Yes, you can disable it in the Text Entry screen of the Settings menu.
