Shoot numbers and blast the UFOs!
“UFO Calculation Brain Training” is an exciting number game that combines mental arithmetic with shooting action. Check the number displayed on each approaching UFO, then fire the number that makes the total equal 10 to destroy it.
The rules are simple, but as the UFOs move faster, you’ll need quicker calculation skills and faster judgment. Since each game can be played in a short amount of time, it’s also perfect for brain training during your commute, on the way to school, or whenever you have a few minutes to spare.
【How to Play】
Drag one of the number rockets from 1 to 9 at the bottom of the screen and place it in the lane you want to fire from. If the number on the UFO plus the number you launch equals 10, the UFO will be destroyed.
Tap a UFO or its launcher to fire the number in that lane. You can earn higher scores by destroying UFOs with simultaneous volleys or when you have only a few rockets remaining.
