"Fancy yourself as being pretty bright? Reckon you're good with spatial puzzles? Prepare to be demoralized. IQ Challenge:Slider is a Symbian implementation of the classic slider puzzles that the elder among us played as a kid in the 1960s. With complete control over the size of the puzzle and how badly shuffled it is, there's a challenge in here for everyone" - Steve from All About Symbian (http://www.allaboutsymbian.com/flow/item/16857_IQ_ChallengeSlider_isnt_kiddin.php)

IQ Challenge:Slider has been ported to Android: the classic number puzzle game with many customization options, UNLIMITED levels up on your own settings.

In IQ Challenge:Slider complexity of the game can be set from easy to extremely challenging independently from size of the puzzle. Puzzle size can be configured from 3x3 to 10x10 enabling anyone finding enough challenges here.

Shuffling the puzzle just slightly gives easy success but trying out on extreme level makes anyone cry easily...

But hey, challenge is good, no pain - no gain, right?

IQ Challenge:Slider is the classic fifteen numbers puzzle on steroids enabling anyone creating own settings for balancing joy and challenge.
