### 5/5 — Great fun!

*2014-05-15, version 1.0*

If you're looking for a game to help you think in different ways, look no further. knx is deceptive in that it starts easy but it slowly becomes more and more difficult. It's a good lesson for kids that the straight route is not always the answer and it's also a great way for adults to keep their mind active. 

I appreciate that there are no add ons — you just play and work out the answers on your own. I also appreciate that once you finish a puzzle it doesn't retain your answer so you can go back and redo them another time.
