The goal of Duality is simple: Navigate the blue orb through the maze and onto the blue target. But the blue orb is bound to the red orb, so the two always move in unison. As a result, if either orb is blocked in a given direction, it's not possible to move in that direction.

To unblock areas of the board, navigate the orbs against force fields, which change the distance between the two orbs and open up new paths through the maze.

NOTE: Despite their simple appearance, some levels can be very hard to solve. However, all of the levels are solvable, and there is always at least one path through the maze which picks up all of the bonuses and reaches the target.
