Ever wished you owned a black hole? Who hasn't, and with Newton's Law you can have a half-dozen!

Tap onscreen, and a black hole instantly appears at that point. And as with any good black hole, space is disturbed, and objects move into orbits.

In each game, there's a wandering planetoid you have to tame by strategically dropping black holes. As they appear in space, their gravity bends the path of the planet, pulling it into an orbit. If you place them well, the orbit will be stable, and you win.

But be careful placing them - too close and gravity pulls the planetoid in; too far, and it'll drift away into deep space. Oh, yeah, don't forget the Slingshot Effect - but that's gravity for you!

And of course, your black holes aren't all you have to worry about...

4 games in one:

• Containment. Drop black holes to keep the planetoid onscreen. But you only have three, and when you try to drop a fourth, the first is 'teleported' over. The longer you keep the planet from drifting off (or colliding into one of your black holes) the higher your score.
  
  
• Solar System. Try to keep the planetoid revolving around the sun by adjusting its orbit with your trusty black hole. But that's not all - do it while all around you black holes wink in and out of existence (yours as well!)
  
  
• Perfect Orbit. It's easy to teleport your black hole around so you can make the planetoid orbit it. But can you get it into a perfectly circular orbit in the time allotted? Well, not perfect: 80% circular will do - just check the display to see your progress.
  
  
• Freestyle. Relax or train - this one doesn't have a score! Have fun dropping up to six black holes, either permanent or 'evaporating', and try to keep the planetoid onscreen.

"Newton's Law" is simple but addictive, with four variations to interest everyone. And like most games, it has the usual high score display, help file, and levels (for higher/lower gravity and speeds).

Does gravity pull at you? Then get Newton's Law, and get gravity on your side!
