Even or odd Mental calculation
Test your mental calculation
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Two answers, more ways to practise. Play Classic, try Sprint 60, learn without a timer and work through 30 mental maths challenges.
Solve the calculation and choose: is the answer even or odd?
Par o Impar combines addition, subtraction and multiplication with short sessions and two large answer buttons. Practise at your own pace or test your speed across five modes:
- Classic: answer before time runs out and try to beat your record.
- Sprint 60: get as many answers right as you can in one minute. Each mistake costs three seconds.
- Daily Challenge: 20 calculations each day, with one official attempt and unlimited practice afterwards.
- Training: choose addition, subtraction, multiplication or a mix. Play without a timer and see an explanation after each answer.
- Challenge Route: complete 30 levels involving calculations, accuracy and memory, and earn medals.
A short tutorial explains the controls. Pause your game, adjust sound and vibration, and check your records. Progress is saved on this device and all game modes work offline. The game interface is in Spanish.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New in this update: Sprint 60, Daily Challenge, untimed Training and a Route of 30 challenges. We have added a new menu, tutorial and results with explanations, corrected the Classic timer, and improved saving, pausing and restoration of previous ad-removal purchases. Your previous best is retained as a historical record, separate from the new rules.
