If you like math, are a quick thinker, and have a flair for competition, then Marco Torretta’s mathematical puzzle game GREG may be just the sort of challenge you’ve been looking for.
The idea behind GREG is simple: Tap the correct combination of numbers on screen to match the total displayed on the top as fast as you can before the timer runs out. The numbers on the board also operate based on a ‘temperature system,’ in that you must cool them down by quickly performing additions, otherwise they start to burn.
GREG, which is derived from the word ‘aggregate,’ is marketed as a brain training game that allows you to showcase your brain power through completing special combos and tricks, and also has the potential to work in educational settings. There are a slew of achievements to unlock, encouraging players to constantly improve their scores and simultaneously their ability to think on their feet when it comes to adding sums quickly. And for anybody who thrives on competition, you can challenge your friends and show off your prowess with in-game leaderboards.
