Four kinds of thinking

Each puzzle family has its own sizes and its own little logic tricks. Every hint explains the reasoning step instead of just filling in the answer.

Sudoku

4×4 for warming up, then 6×6, 8×8 and the classic 9×9. Pencil marks and smart notes included.

Nonogram

Number clues reveal a hidden picture, from 5×5 to 15×15. Drag to fill whole rows.

Logic grid

Who loves mangoes, who plays the tabla? Read the clues, tick and cross until every friend is matched.

Number cross

Fill each run so it adds up to its clue, with no repeated digit. Small sums are your friends.

📅

One pack a day

Built on your phone from the date, so the whole world gets the same four puzzles. Finish all four to grow your streak.

Meet Neuro

Neuro is a calm, curious jellyfish who lives on the puzzle reef. Her eight tentacle tips light up as you solve, and she whispers a tip when you need one. She'd never tell you the answer, but she'll always show you how to find it.

Look out for Noodle the snake, who sometimes pops in to say hello.

🛡️ Calm, private and fair

No ads, no in-app purchases, no accounts, no chat.
Nothing leaves your device: progress, streaks and report cards are stored only on your phone.
Works offline. The daily pack is built on your device.
A grown-up check guards every link that leaves the game.
The score is a fun measure of speed against par. It is not a medical, IQ or "brain age" test.
