What is your IQ level? Boost your brain power and improve your mental and cognitive skills.

"Intelligence Benchmark" app is a general psychometric intelligence test targeting both humans and machines. Enjoy a specially crafted set of experiments designed to challenge your mind and help you think out of the box.


For each task, you will be given a set of examples where each example has one input grid and its corresponding output grid. These examples will help you understand the relationship between input and output for that specific task. Once you grasp the idea, your goal is to construct the output grid corresponding to the test input grid. "Constructing the output grid" involves picking the height and width of the output grid, then filling each cell in the grid with the appropriate color. Only exact solutions (all cells match the expected answer) are considered correct.

Challenge your friends! How many tasks can you finish in 5 minutes?

Very challenging

Very challenging! I was stuck at first but then it started to make sense. My wife and I had fun seeing who could get to level 6 first without hints - she won :) GREAT!
