Puzzles that punish the obvious answer and reward lateral thinking

TubeGames verdict
Riddles that cheat first so you learn to cheat back; funnier than it is fair, and I kept going.

Brain Out is a stack of trick questions dressed as puzzles. Each screen looks like a first-grade worksheet, and the first-grade answer is wrong. My first feeling was mild outrage: I gave the obvious answer to the first equation and the game told me, kindly, that I'd been had.
The loop is the grudge. You know the honest answer, the game rejects it, and now you're poking the screen, dragging things that shouldn't drag, rereading the question with a lawyer's eyes. When the trick lands it takes three seconds and you laugh. When it doesn't, you try everything for five minutes and feel stupid. That cycle is why people finish it in one sitting. The equations where you add a single line are the ones everyone asks about, and a fair test of whether you'll like the rest.
Complaints: some answers are arbitrary rather than clever, and a few depend on a phone gesture that doesn't translate to a mouse. Difficulty is uneven; a great puzzle is followed by one you solve by tapping everything. The humor is broad, forwarded-meme broad.
Play it if you like riddles where the trick is the point and you'll forgive a cheap one for every good one. Skip it if you want puzzles with rules; Brain Out's only rule is that you're wrong.
Good
- Genuinely funny when a trick lands
- Levels take seconds, so a try costs nothing
- Rewards reading the question, not math
- Great for passing the phone around a table
Not so good
- Some answers are arbitrary, not clever
- A few gestures don't translate to a mouse
- Humor is broad and dated
About Brain Out
Brain Out is a popular, globally acclaimed game, combining IQ challenges and reverse thinking in engaging puzzles.
Brain Out was published on YouTube Playables on 2023-08-16 by EYEWIND LIMITED. In 1151 days it has reached about 7.7M plays.
Brain Out is a set of short riddles where the straightforward answer is usually the wrong one. Each level looks simple until you try it, and solving it often means using the screen in a way the puzzle never mentioned.
Levels take seconds when they click and much longer when they do not, which is the whole point. It is easy to dip into for a few puzzles at a time, and it runs free inside YouTube with nothing to install.
How to play: Tap, drag or move things on screen; the solution is rarely the obvious one.
Good for: riddle fans, short brain breaks
How to play Brain Out
- Phone / tablet
- Tap and drag anything on screen, including the question text, the buttons and the edges of the picture; nothing is off limits.
- Desktop
- Click and drag with the mouse; the puzzles that assume a touchscreen are the ones to expect trouble on.
- Levels
- A long run of one-screen riddles. In the phone version level 203 is the one people search for most, which tells you where the wall is.
- Progress
- Levels unlock in order and a solved one stays solved.
The question is part of the puzzle. Most tricks hide in the wording, or in the assumption that the screen only does what a screen normally does.
Tips for when you're stuck
- Reread the question as a lawyer. 'Which is biggest' and 'find the number' are traps of wording. The literal reading is usually the one the game wants.
- Touch what isn't supposed to move. Titles, buttons, the frame, the answer box. If something looks static, drag it.
- Do the dumb thing on purpose. Some levels want the childish answer, not the clever one. If you've been clever for a minute, try being five.
- Walk away for a minute. The trick you can't see is usually a category you're not looking at. Tea, then back.
- Don't look up the answer yet. Once you read one solution you'll read all of them, and then the game is a video you tap along to.
Brain Out vs Brain Test
Brain Test is the other big trick-riddle game and the two get confused constantly. Same format: one screen, a question, an answer that isn't the obvious one. The difference is tone. Brain Test leans on little characters and situations, so its tricks tend to be about the scene; Brain Out leans on the interface, so its tricks tend to be about the screen itself, the buttons and the text of the question. I find Brain Out meaner and funnier, and Brain Test more consistent. If you've finished one, the other will feel familiar for the first ten levels and then start to surprise you.
Brain Out answers: the one rule that solves most levels
I'm not going to list solutions; the puzzles are the whole game and a walkthrough turns it into a video. But there is a rule that gets you through most of it. Every level lies to you in exactly one place, and the lie is either in the wording of the question or in what you assume the screen can do. So when you're stuck, stop trying harder and change the category: if you've been thinking about the picture, read the sentence; if you've been reading the sentence, drag the picture. The famous add-one-line equation is a wording trick. Most of the others are screen tricks. That's the whole cheat.
