Sync-Ball launched simultaneously on iPhone and iPad

Forget synchronising watches - balls are where it's at.

Sync-Ball demands you drop each coloured ball into the holes provided. The catch is that swiping one ball will cause all the balls to move in the same direction.

The challenge is to find a direction to swipe in which keeps every sphere safe. Walls can be used to keep certain balls in place while you move others into more useful locations.

Initially starting with two balls at your disposal, later levels up the ante with four balls to simultaneously control.

There's a lovely isometric graphical style to it all, with 80 levels in total to puzzle your way through.

Creator Brett Ballow hopes that the lack of scores and time-limits will deliver "a stress-free challenge, because there's no penalty for restarting a level as often as you want."
