Left-click your mouse to select answers on a desktop browser. Touch controls also work if you're playing on a mobile device. Pro tip: keep your cursor near the center of the screen so you don't accidentally click the wrong shape when a timer is ticking down.
Stupidity Test is a straightforward browser puzzle game that throws basic logic questions at you until you inevitably mess up. The questions start with simple math and shape recognition. Honestly, the real challenge kicks in around question 10 when the game throws tricky color traps at you, expecting you to click the wrong thing out of pure habit. This part gets repetitive after 30 minutes. Anyway, it's a decent distraction for anyone who wants a quick ego check on their lunch break. The game shows your final score at the end of the test, or instantly if you make a mistake. It's built for desktop but works on phones too.

Each round takes about 5 to 10 minutes depending on how fast you read. You get a series of prompts asking you to identify colors, count shapes, or solve basic equations. Here's the thing: the game uses misdirection. It might show you the word 'Red' written in blue text and ask you to click the actual color. That's where I kept messing up during my first 20 minutes. Read every single prompt twice before clicking. The game ends the second you choose the wrong answer, which is honestly frustrating when you're on a 15-question streak. There are no save points.

I wasted 20 minutes before realizing the game counts 'selecting the box' differently than 'clicking the text inside it.'
Don't rush the first 5 questions; they lull you into a false sense of speed.
Watch out for double negatives in the math prompts.
Keep your mouse hand relaxed so you don't jitter-click the wrong shape.

Unlike most generic trivia games, this one focuses on tricking you rather than testing actual knowledge. The visual speed bumps make it a solid game to play once. The downside is it lacks real long-term progression, but beating a personal high score of 20 correct answers feels pretty good for a free browser game.
