They're implemented using JavaScript and can be installed via npm packet manager.

Install

npm install -g braingames-dkedition

Example	Usage
	`brain-even` Player is shown a random number and must reply with yes if it is even and no otherwise.
	`brain-calc` Player must solve randomly generated mathematical expression.
	`brain-gcd` Player is presented with two random numbers and must reply with their greatest common divisor.
	`brain-balance` Balanced number is such that it's smallest digit differs from the largest one by no more than 1. To balance a number one can subtract value from some digits and add it to others. Player is expected to find a balanced number that has it's digits in ascending order. For example, instead of 322 or 232 one should input 223.
	`brain-progression` Player is presented with a series of numbers that form a part of arithmetic progression. Player's task is to fill a missing spot in that series.
	`brain-prime` Player is shown a random number and must reply with yes if it is prime and no otherwise.
