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.
- 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 don't catch it, the speed increases.
- the 100 points, to get extra points. If you don't 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!
