SavvyBrain is a calm puzzle collection for focused thinking — no ads, no countdown pressure, no manipulative tricks to keep you playing.
Five puzzle types, each one exercising a different kind of thinking:
MEMORY MATCH
Find every matching pair in the fewest moves.
• Three grid sizes — Easy, Medium, and Hard
• Track your best move count for each size
SLIDING TILES
The classic 15-puzzle — slide numbered tiles back into order.
• Three grid sizes: 3×3, 4×4, and 5×5
• Every puzzle is guaranteed solvable
• Track your best time for each size
SUDOKU
Classic number logic and deduction.
• Three difficulty levels — Easy, Medium, and Hard
• Every puzzle has exactly one solution
• Track your best time for each difficulty
FREE THE BLOCK
A sliding-block escape puzzle — clear a path to slide the target piece to the exit.
• Three difficulty levels, each checked for genuine challenge (not just piece count)
• Track your best move count for each difficulty
CALENDAR PUZZLE
Fit ten pieces onto the board so that only today's month, date, and weekday are left showing. It's the same genre as the popular "puzzle-a-day" calendar puzzles, brought to your phone.
• Play today's date, or pick any date from 1900 through the current year
• Rotate and flip pieces to find a fit
• Stuck? Use up to 3 hints per puzzle
• Track your best solve time for each date
• Replay any date as many times as you like
• Reset the board anytime if you want a fresh start
• Share a picture of your solved board when you're done
KEEP YOUR PROGRESS
Optionally sign in with Google Play Games to back your progress up to the cloud and carry your best scores to a new device. Entirely optional — the app works fully offline with no sign-in.
BUILT TO BE EASY ON YOUR EYES
• Muted, low-saturation colors by default — nothing neon or jarring
• A true dark mode, not just an inverted light theme
NO DARK PATTERNS
No forced ad-watches, no artificial lives or energy systems, no countdown-pressure mechanics. Just a puzzle, whenever you want to play it.
PRIVACY-FIRST
No account required to play. No ads or trackers of any kind. Your progress stays on your device unless you choose to back it up — see the privacy policy for full details.
More puzzle types are on the way as SavvyBrain grows. This is just the beginning.
