How many world flags do you think you can recognise? 20? 30, perhaps? What about if you had the pattern of each but had to say which colour went where? Far, far harder. It even took me a few taps to get my own country's flag right, in this, Colour The Flag, shown below, a £1 commercial title in the Nokia Store.

The game's simple, but hard to actually complete, as the flags get more and more obscure and more complex; (right) a suitable palette is provided for each flag, though you won't know which colours are actually needed....

Unless you ask for a hint, in which case the 'wrong' colours are automatically removed. Use the hints sparingly though, as you'll need them more on the harder flags! ; (right) there are six flag packs, in increasing order of obscurity and complexity

You can take the flags in any order - complete a certain number in a pack and you unlock the next one; (right) you can also earn extra hints, to keep your chances of completing all the flags alive...

...if you complete the flag in few enough taps; here I'm doing quite well, albeit still on flag level pack 2!

A simple and colourful title that will appeal to anyone who finds geography and trivia fun - and who isn't colour-blind! You can buy Colour The Flag here in the Nokia Store.
