20Q is a device which asks you 20 simple questions such as "Is it larger than a loaf of bread" as it trys to guess what item or animal you are thinking of.
Priced around £10, this game is a fun little thing to show off, or to keep children occupied for half an hour or so.

The device has quite a nice form factor, with buttons to press for the answer you want to give that aren't just yes or no, buttons on the side to increase the speed of the text on the LED screen, and a nice elliptical shape that is comfortable to hold.
However, the LED screen is very uncomfortable to read, especially when set to the higher speeds if you want a quick game. The red writing is not complimented by the orange shell surrounding my own personal device. Sun glare is also an issue, and it makes the screen impossible to read.

The game itself often does actually work, around 8 out of 10 times. Sometimes it is quite impressive, but other times it just isn't, and it seems to be pot luck, however, chances are high it'll get what you're looking for. If it doesn't it has another 5 questions (so 25Q) and if it doesn't get it in those, you win! It must be said, you are likely to get bored of it quite quickly, once the novelty of it knowing you were thinking of a whale or something wears off

Overall, fun for a short while, but essentially just a dust gatherer in the long run.
