In this game there is a grid, and on that grid you can move the coloured spheres anywhere. Not by placing them, but by sliding them. If another colour is in the way, it will go around.

The object is seemingly simple: slide the same coloured spheres into rows of five. However, after each move, three more spheres join the board. It's your goal to attempt, to keep enough of the board clear in time for the next move.

This can be achieved with greater ease by, not surprisingly, making rows. After each successful group of five you remove from the board, there are no additional spheres put on the board. If you use this strategically, you can clear much of the board in one go.

Like all puzzle games, there is no long time goal. The object is simply to keep the game going as long as possible. Luck does play a part, but the strategy needed is clear. Don't let the shonky graphics fool you - this is a neat little puzzler.
