About Brain Test: IQ Challenge

Brain Test: IQ Challenge collects short brain teasers drawn in a hand-sketched cartoon style. The first level asks you to find the longest one among a belt, a snake, a red and teal truck and a small drawing of a bridge, while a startled cartoon face peeks out from behind them.

Other puzzles test pattern recognition, ask you to pick the odd one out or have you work through sequences, and they are meant for players of all ages. Play with mouse clicks and movement, or tap the screen on a phone or tablet.

A key counter in the top right shows 35, and the top left holds a settings button and a restart arrow for trying a level again.
