## What is MonoBrain?

MonoBrain is a brain-training app built around classic number logic - the kind of puzzles you know from intelligence trainers, generated fresh every time you play.

FIVE GAME MODES
- Number Sequences: spot the hidden rule and continue the series
- Magic Squares: fill the grid so that every row, column and diagonal adds up
- Number Pyramid: each block is the sum of the two below it
- Number Analogies: find the relationship between two numbers and apply it
- Number Scale: symbols stand for numbers; crack their values from the equations

FIVE DIFFICULTY LEVELS
From Beginner to Genius: higher levels don't just use bigger numbers - they need more steps, cleverer combinations and second-order patterns. Every puzzle is generated so that it can be solved by pure logic, without guessing.

TROPHIES AND STREAKS
Answer correctly in a row to earn Bronze, Silver and Gold trophies for every mode and level. Trophies are earned one after another - first Bronze, then a fresh streak for Silver, then Gold.

LEARN FROM EVERY TASK
If you get one wrong, MonoBrain shows you the rule behind it. If you get it right, you can reveal the explanation on demand.

- Thousands of possible puzzles, no repeats in a row
- Short rounds of five tasks - perfect for a coffee break
- Works completely offline
- Available in English, German, Danish, Dutch, Spanish, French, Italian and Portuguese

Free to play, supported by ads. Ads are never shown while you are solving a puzzle.
