Train your focus, memory and math skills.
About this app
Train your brain with fun mini games that challenge your memory, focus, logic and math skills. Braincup offers 26 brain training exercises designed to sharpen your mind and improve concentration.
Mental calculation: Follow the mathematical expressions. Use the result as the base for the next calculation.
Chain calculation: Solve complex formulas step by step.
Sherlock calculation: Find a formula to reach the goal using only the given numbers and operators.
Fraction calculation: Solve the fractions.
Value comparison: Select the expression with the highest value.
Anomaly puzzle: Find the figure that stands out. Consider both the color and shape of each figure.
Pattern sequence: Find the next figure in the pattern by looking for repeating shapes, colors and rotations.
Path finder: Start at the marked position and follow the arrow instructions to find the destination.
Visual memory: Memorize the shapes on the grid, then identify the hidden shape after the timer ends.
Ghost grid: Watch the tiles light up one by one, then tap them back in the same order.
Color confusion: Tap all cells where the word matches its font color. Stay focused!
Colored shapes: Add up the points from the correct statements.
Orbit tracker: Watch the highlighted balls, then track them as they move. Select the original targets after they stop.
Flash crowd: Dots flash briefly on each side. Tap the side that had more dots. Trust your instinct!
Mini sudoku: Fill the small grid so every row, column and block contains each number exactly once.
Mini chess: Finish the chess scenario as white. Checkmate the CPU before it checkmates you.
Lights out: Turn off every light. Each tap toggles the cell and its four neighbours.
Sliding puzzle: Slide tiles into the empty space to put them back in order.
Shikaku: Divide the whole grid into rectangles. Each rectangle holds exactly one number, equal to its area.
Nurikabe: Paint cells to build the sea around numbered islands without forming any 2x2 block.
Cat queens: Place one cat in every row, column and color zone. No two cats may touch, not even diagonally.
Schulte table: Tap the numbers in order from 1 upwards as fast as you can.
Flags: Identify the country by its flag. Each round adds more options and the clock is ticking.
Digit memory: Memorize a digit sequence, solve a quick math problem, then recall the digits.
Spot the new: Tap the animal you have not seen before. One mistake ends the game.
Wordle: Guess the hidden five-letter word in six tries.
The game has several achievements and each exercise has medals to keep you motivated.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.inspiredandroid.braincup is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 2.27.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall Braincup first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Braincup, and a listing is removed when the evidence for it stops holding up.
