Graph Blaster

Legend has it that René Descartes came up with the coordinate plane while lying in bed, watching a fly crawl across his ceiling and wondering how to describe exactly where it was. Graph Blaster puts you in his place: spin the x and y knobs to aim, and zap the bugs before they get away.

How to play

  • Y knob (top left): turn it to move the scope up and down the y axis.
  • X knob (bottom right): turn it to move the scope left and right along the x axis.
  • Zap: tap both knobs at the same time. The readouts show your exact (x, y) coordinates.
  • A bullseye, with the whole target inside your scope, scores 50% extra. Hits in a row build a combo.
  • Each stage has a quota and a timer. A miss costs 2 seconds. Later stages bring faster bugs, more at once, and a smaller scope.

Pro

One $3.99 purchase removes all ads and unlocks every screen color, target, scope and zap effect in Customize. It works on all your iPads and iPhones signed in with the same Apple Account. Free players can play every stage.

Help

The zap doesn't fire.
Tap both knobs at the same moment (within a quarter of a second). On iPhone, use one thumb on each knob.
The knobs feel backwards.
Open Customize from the main menu and turn on "Reverse Y knob" or "Reverse X knob". It's free.
