If you get stuck during a puzzle, hints are available to help.

You can choose between three types of hint, using the buttons beneath the puzzle:

Pencils - Automatically fill all possible pencil numbers in the puzzle.

Solve - Automatically solves the next cell, showing you which rule was used.

Errors - Any incorrect numbers in the puzzle will be highlighted red so you can find and remove them.

If you run out of hints, you can watch a video to receive more of them. Tapping the desired hint's icon while no hints are remaining will start playing a video automatically. Please note, an internet connection is required to watch ads.
