NumeriKill

Numerikill turns math practice into an action game! A math question appears at the bottom of the screen and three alien ships come flying at your rocket, each one carrying an answer. Tilt your phone or tablet to steer and dodge, then tap the alien with the correct answer to blast it with your laser. ZAP! The next question comes right away – how many can you get before the aliens catch you? • Right answer: +2 points and a big a burst of stars and confetti! • Wrong answer: −1 point, and that alien flashes and gets knocked back • Fly off one edge of the screen and pop out on the other side! FOR GROWN-UPS • Choose addition, subtraction, multiplication and/or division • Show questions with words (7 plus 5) or math signs (7 + 5) • Choose number ranges (up to 10, 100 or 500 for adding and subtracting; up to 10, 20 or 40 for multiplying and dividing) • Slow, regular or fast speeds for the lasers, the aliens and the rocket • Optional password lock on the Options screen so kids can't change the settings • Calibrate the tilt to the way your child holds the device • Scores are kept on the device No ads.
