## What is Deadly Divisors?

Deadly Divisors is a game of timing, mathematical skill and instant game over (if you make a single mistake).

You are on a number. When you tap your screen you advance to the next number. If it is a divisor (or your number divides the next one) then you score points; if it is not a divisor then it is game over.

Practice your mathematical skills and reactions, while trying to set a new high score.
