Enigmo was one of the more original iPhone launch games, and has already scooped several awards to prove it.

Now its developer Pangea Software has announced a seven-day price promotion, selling the game for $5.99 instead of $9.99 in the US.

Here in the UK, that means you can get the game for £3.49, at least until next Wednesday.

The game sees you moving and rotating puzzle pieces to manipulate streams of flowing liquid through levels to their destinations. It's a The Incredible Machine for the 21st century. Sort of.
