Everything you need to know to play. For quick answers, see the FAQ.

Just for fun

Brain Twisters is made for fun and entertainment only. It is not a medical, health, therapy or educational product, and it is not meant to diagnose, treat, cure or prevent any condition.

We make no claim and give no guarantee that playing will improve your brain, memory, attention, intelligence or any other ability, and the app offers no health benefits of any kind. Points, levels and streaks are part of the games; they do not measure your abilities.

The app is provided "as is", without warranties of any kind. To the fullest extent the law allows, the developer is not responsible or liable for any loss, damage, injury or other consequence that comes from using the app or from not being able to use it. You use the app at your own risk.

If you have concerns about your memory, attention or health, please talk to a doctor or another qualified professional.

Getting started

The app has three tabs at the bottom of the screen:

Home: Your daily streak and points, the games you played most recently, and then every game grouped by skill. Tap a game to open its setup screen.
Stats: Your points, streaks, streak freezes and a calendar of the days you played, then totals for each skill and each game. "How points work" explains the scoring.
Settings: Look and feel, language, sound, vibration, the daily reminder, your data, and these pages.

Levels

Puzzles and quick games have 5 levels: Easy, Medium, Hard, Expert and Master. Games against the computer have 8 levels, from Beginner to Master. The first level of every game suits children; adults usually start at Medium.

Learning a game

Every game has a "Watch how to play" button on its setup screen. It plays a short animated lesson, then a sample game. It never starts by itself, and you can pause it, step back or forward, skip to the sample game or close it at any time.

The games

Memory

Sequence memory: Watch the tiles light up, then tap them in the same order. The pattern grows by one each time.
Pair match: Turn over two cards at a time and find every matching pair of pictures.

Attention

Schulte table: Tap the numbers in order, from 1 upwards, as fast as you can.
Stroop: Tap the colour of the ink, not the word you read. The Easy level uses arrows instead of words.

Logic

Sudoku: Fill the 9×9 grid so every row, column and 3×3 box holds 1 to 9 once.
Nonograms: Use the number clues beside each row and column to fill in cells and uncover a picture.

Maths

Make 24: Combine the numbers with + − × ÷ to reach the target.
Kakuro: Fill the white cells so each run adds up to its clue, with no number used twice in a run.
Calcudoku: Fill the grid so every row and column holds each number once, and each cage makes its number with its sign.

Spatial

Unblock: Slide the blocks along their lines to let the key block out on the right.

Strategy

Chess: Play the computer at 8 levels, or a friend on the same phone.
Reversi: Place discs to trap and flip your opponent's discs. Most discs at the end wins.
Checkers: Move diagonally, jump to capture, and reach the far side to crown a king. Captures are compulsory.
Four in a Row: Drop discs into the columns. The first to line up four wins.
Ali Guli Mane: A traditional South Indian sowing game. Sow seeds around the pits and capture the most.
Aadu Huli: A traditional game of goats and tigers. The tigers jump to capture goats; the goats try to trap the tigers. There are two boards to choose from.

Points, streaks and coins

You earn points when you finish a scored game. Harder levels earn more, and there are bonuses for playing without hints or undos, for quick solves and for big wins.
Losing to the computer or missing a quick game's target still earns 5 points for finishing.
Your daily streak grows by one each day you finish a scored game. Each game also keeps a win (or solve) streak, which starts again when you lose or miss a target.
Every point also gives you 1 coin. Spend 200 coins on a streak freeze on the Stats tab. Your score never goes down.
A streak freeze is used automatically on a day you don't play, so your daily streaks don't break. Freezes cover up to 3 missed days in a row, and you can hold up to 5. You get 1 free freeze the first time a streak reaches 7 days.

Hints and undo

Puzzles and board games offer hints. Against the computer you can also undo up to 3 times per game; each undo takes 10% off a win or draw. Any hint or undo loses the +25% no-help bonus. Quick games have no hints or undo.

Mistakes and unfinished games

In Sudoku, Nonograms, Kakuro and Calcudoku a wrong entry turns red, and 3 mistakes end the puzzle. If you leave a puzzle or a board game, it is kept so you can continue later. Leaving a quick game in the middle of a round records nothing.

Pass & play

Chess and the other board games can be played by two people sharing one phone. Pass & play games don't earn points or count toward streaks.

Settings

Style: Calm is soft and easy to read. Playful is bright and bouncy.
Theme: Light, dark, or follow your phone.
Text size: Four sizes. It changes the text on every screen.
Colour-blind friendly colours: Stroop switches to colours that most people with colour blindness can tell apart.
Language: English, Hindi, Kannada, Tamil, Telugu, Malayalam, Spanish, French, German or Turkish. These help pages are in English.
Sound effects and vibration: Turn each on or off.
Daily reminder: A notification at the time you choose. Android asks you to allow notifications the first time you turn it on.
Reset all progress: Deletes all scores, streaks, coins and unfinished games. Your settings stay. This can't be undone.

Playing comfortably

Take regular breaks, and stop playing if your eyes, hands or head feel tired or sore. An adult should help young children and keep an eye on their screen time.
