This game truly takes thinking outside the box to another level. I can honestly not praise the ingenuity of the many puzzles enough. 

Blackbox isn't just a touch screen puzzle game, it uses functions such as the volume buttons, settings switches, the shutting down of your phone, chargers, microphone to detect noise and much much more. Every single puzzle to light up the boxes is guaranteed to bring more elements of the phone that we use everyday to solve what would otherwise be an impossible challenge. Starting off with basic functions such as volume and tilting your phone, it develops in an incredibly clever and interesting way with every puzzle. Of course, there will be hints if you are really stuck, don't worry. 

With delightfully funny commentary, plenty of “ah-ha” moments, and the fact that I will praise it to the moon and beyond, there's really nothing I can criticise about this remarkable app when I want a challenge.  This can also be something of a competition within your families too, just to add a little competitive spice and laughter in these trying times.
