This is a deceptive game that pulls you in with a few simple levels before upping the ante with some far more taxing puzzles.

The game is played on a board 5 x 5 square containing various playing pieces of different shapes and colours randomly placed around the board. Your task is to merge identical pieces together, at which point they are cleared from the board.

The problem is that pieces can only be merged when they are aligned horizontally or vertically, and pieces cannot be moved, other than for merging purposes.

The trick is that pieces can be broken down into several individual components. For example, the egg shapes in the image above are in fact made up of a big circle and a small ball. Move this onto a big circle shape and you are left with just a small ball.

This is the sort of game where each level has to be solved in your head before any pieces on the board are moved.
