Game: "Check for parity"

The essence of the game is as follows: the user is shown a random number. And he needs to answer Yes, if the number is even, or No - if odd. Any incorrect entry is considered an error, for example, n and is equivalent to an incorrect answer.

How to play

$ brain-even

Game: "Calculator"

The essence of the game is as follows: the user is shown a random mathematical expression, for example 35 + 16, which he/she needs to calculate and write the correct answer.

How to play

$ brain-calc

Game: "The greatest common divisor (GCD)"

The essence of the game is as follows: the user is shown two random numbers, for example, 25 50. The user must calculate and enter the greatest common divisor of these numbers.

How to play

$ brain-gcd

Game: "Balance"

A balanced number is a number in which the smallest digit differs from the largest one by more than one.

Examples of balanced numbers are 111, 233, 55, 001, 9999, 0001.

And, for example, the number 123 is not balanced because the smallest digit in it is 1, and the largest one is 3, and the difference between them is 2. When balancing the numbers, "large" digits give the excess "smaller" so that the number eventually becomes Balanced. In the case of the number 123, the number 3 should give the number 1, and in the end we get the number 222.

The order of digits in a balanced number is in ascending order. For example, instead of 322 and 232, you need to specify 223.
