App Name: 27 – A Spatial IQ Puzzle [Android, iOS Game]

Cost: Free

Developer: 9th Impact

App Market: Download Page


The studio, best known for their Biker Mice from Mars endless runner and strategy games are taking their first steps into the ‘brain-training’ genre with 27.

27 is a unique puzzle game that is scientifically guaranteed to improve your spatial IQ. Your goal is simply to clear all the 27s from the board. The game gives you a deck of 4 numbers. You can place these numbers anywhere on the board. Your deck refreshes with a new number each time you place one. Three of the same number in a row will produce the sum and the newly formed number will appear in the grid space where the final number in the row was placed.

Sounds simple, right? But of course, there’s tricky designer placement, board congestion, blocked grid spaces, exploding numbers and the damn luck of the deck to contend with!

A perfect casual pick up and play puzzle game that will keep your brain entertained for hours. If you love playing Sudoku, are obsessed with testing and improving your IQ or are a fan of 2048 then “27” is for you!
