OperAnd is a game that can help you to keep the mind fit.
It will show you operations where an operand is missing and you will have to choose from the proposed solutions.
Tap:
- a number, to choose it as solution. If you are right, you get points; otherwise, you lose points and a life.
- the turtle, to temporarily decrease the speed of the game. If you dont catch it, the speed increases.
- the 100 points, to get extra points. If you dont catch them, you lose points.
- the heart, to get an additional life.
Tap and hold a number to destroy it. If it is not the solution, you get points; otherwise, you lose points and a life.
Both the numbers and the turtle, the 100 points and the heart, appear, move around and disappear.
The goal: To reach 1,000 points in the minimum possible time.
Have fun and good luck!
