Moving on to something weirder, use all of your powers of coordination to guide your Impossaball through eight levels of 3D mazes and corridors.

The idea is to squash all of the cylinders you find in your path by bouncing on them while, at the same time, avoiding the many obstacles in your path.

Touch a spike and bang goes your ball. Touch a column and you'll find yourself reeling with the shock. You'll also find Plasma Fields and Fire Bolts scattered around the maze, which should be skirted at all costs.

Impossaball is infuriatingly good fun and you'll need to be very quick indeed to dance out of the way of destruction. Look out for the magic rings that can offer you much needed extra lives but, be careful, they can also deal out death.

As with most puzzle-oriented games, the simpler the idea, the better the game and, true to that maxim, Impossaball is a challenge you'll want to come back to again and again.
