Maybe not. According to Pine Entertainment, their "very simple math game" might actually be the most "challenging" ever.
An exaggeration, no doubt.
Based on screenshots and the video below, it's clear the challenge of 1+2=3 – a new, free iOS game – comes more in its demanding reflexes than its arithmetic.
Similar to math puzzler Sumico, 1+2=3 asks you to answer simple math equations against the clock.
Given most people can work through the game's "problems" with just a quick glance, the real challenge here seems to be hitting the right answer fast enough.
If you're into quick, tap-based reflex games and are fond of numbers, even the small ones, give 1+2=3 a try on iOS for free.
