Odd Even Math Brain Trainer
Noutilapy is a pure math brain training game designed to sharpen your mental arithmetic every day. Each level gives you a unique math equation. Solve it in your head and decide whether the final answer is an odd number or an even number. It sounds simple, but as levels progress the equations become more complex and the timer keeps pushing you harder.

3. Tap ODD or EVEN to classify the result.
4. If the countdown timer is active, answer before time runs out.
5. Use the hint button if you need a clue. Hints are limited so use them wisely.
6. Complete the level to earn up to three stars based on speed and accuracy.
7. Unlock the next level and keep climbing through all 50 challenges.
