Magnetic Attraction
Gemstones of the same colour are magnetically attracted to each other, which can be a great advantage in times of danger.

If a group of Gemstones is getting close to the danger point, you can pull it back to join the group behind it. Check the colour of the closest Gemstone in the rear group, and then launch a Gemstone of the same colour at the back of the endangered group.

The magnetic attraction of the two Gemstones will pull the endangered group back to the group further down the track.

Multicolour Bomb
The Multicolour Bomb is a lifesaver when you have a line of Gemstones teetering on the edge of the danger point. Multicolour Bombs destroy all Gemstones of a certain colour; for instance, flicking a Multicolour Bomb at a red Gemstone causes all red Gemstones on screen to disappear. Multicolour Bombs only appear occasionally, however.

Rocket attack!
From time to time, rockets appear to push the Gemstone line at a higher rate of speed. You must destroy them quickly by hitting the rocket with a launched Gemstone or by destroying all Gemstones in front of the rocket.
