Kick start a chain reaction.
Casey's story is a familiar one: a bored child, a house filled with random objects and an endless desire to create elaborate contraptions out of anything that comes to hand.
In the case of my own irrepressible five year-old, the living room has recently become his own personal Tardis. The Dyson becomes the console, the guitar amps the control panel. In Snappy Touch's more conventional imagination, though, you're generally tasked with fashioning a cunning chain reaction to achieve a goal.
A table, a football, a ballon, a pair of scissors and a boxing glove suddenly become a challenge to pop a balloon. A carefully stacked pile of books must be completely knocked down using nothing more than an eight ball, a pipe section and a boxing glove on an extending arm. The trick is arranging them just so.
Being a touch screen affair, placing and rotating objects is second nature, but finding a solution can often require far more trial and error than you bargained for. Fortunately, not only does Casey provide his own solution, you can see your friends' attempts via the neat Game Center integration.
Once you've worked your way through the 70 or so levels, creative types can even come up with their own devious contraptions and challenge their pals over email.
If you've somehow lost your inner child, you might find it skulking impishly in the confines of Casey's Contraptions. Even the price is from your youth.
