Best IQ Test for Android

By bubble quiz games Free Editors' Rating

Editors' Review Staff Apr 22, 2014

Test your IQ, and tweak your brain with IQ Test: Cryptex Challenge on your Android device. This free app from Bubble Quiz games challenges players of all levels with clever math and logic puzzles. You can buy Hints and even Solutions when you're stuck, but it'll cost you some IQ points.


Brain booster: IQ Test's puzzles and logic problems will challenge your reasoning skills and stimulate your cognitive powers. It's a workout for your brain.

Tricky, too: Just when you think you've got it down, IQ Test throws you a curve with an unexpectedly easy solution.

Fun for a math test: We had fun playing IQ Test: Cryptex Challenge, despite being constantly humbled and occasionally humiliated. It's a challenge, but that's the point.


Tumbler fumbler: It's way too easy to tap the Check button while you're still setting your answer on the tumbler wheels, triggering errors that cost you IQ points.

Left-brainy: Like many so-called IQ tests, these quizzes and puzzles are heavy on the math, which is easier to quantify than other important components of intelligence. Nerds will love this app; artsy types, not so much.

Bottom Line

We had fun taking the Cryptex Challenge, even if the experience was a bit humbling. We didn't mind trading IQ points for Hints since the challenge, not the score, was the object, and the Hints helped point us in the right direction when we were stumped. Left-brain or right-brain, IQ Test: Cryptex Challenge not only boosts your brainpower but makes you think you're having fun instead of taking a test!
