The game is more challenging when you have to figure out the word in a given time frame. Configurable timer value is a plus. This would be an addition to the desktop frontend. The mobile (Harmattan) frontend already has this feature so the logic is clear. Extending the handbook would also be a plus about this feature with screenshots. There is no bugzilla entry for this feature yet, but it is very similar to what has been reported against the kanagram project in theory.
