About this APK

Primes! is a game by Rusca8 in the Educational category, listed since at least February 2021. It includes native code only for x86 32-bit, ARM (legacy) and ARM 32-bit, so it won't run on 64-bit-only phones such as recent Pixels.

It asks for 2 permissions, none of them sensitive.

What's new in v1.0.5

Got rid of the ads because they were giving me headaches and also not money. hahahah

Description

From the listing uploaded by “appupdater”.

"Primes!" is a math game where you run against the timer decomposing numbers into their prime factors. You start with 30 seconds, and a pile of number balls. The game sets you a target, and you must choose its factors (e.g. target = 12, factors = 2,2,3) in order to destroy them. If you press the wrong factor, the target will explode and add its correct factors to the pile. If you clear the screen, you get extra time, the difficulty level increases and a new set of balls falls. The game comes with a Ranking of the 5 best scores, so you can see how close you are to be the best factor decomposer in town :D I wonder if this could be helpful in primary schools, like an engaging way of teaching prime factors. Maybe time will tell...

Primes! APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Primes! APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Unknown. After downloading, check that the file's MD5 is 6d843a82461322ee729cb76df0089f37.
