(First start in package making & publishing)

Project is made during studying the web-dev on Hexlet.

It includes 6 simple math games to be launched as console applications. To see all possible games to play You should just type brain-games in your command-line. You'll see an invitation, name-input line and a games list with their ordinal numbers:

Welcome to the Brain Games!

What's Ur name, dear guest ?: zorro
Hello, zorro !


[1] makeBalance
[2] simpleCalculator
[3] isEven
[4] GCDgame
[5] primeNumber
[6] progression
[0] CANCEL

Choose a game number from the list above [1...6 / 0]:

All of them have next common logic:

1) after launching a game a description of this game appears(example):

 `Is this number prime?`
 

2) then the game will ask You to input your name:

 `What's Ur name, dear guest ?: me
 Hello, me !`

3) after that You have first task displayed with a random number(s) (example):

 `Question: 15`
 

If your answer is correct

 `Your answer: no`,
 

You get the approval message

 `Correct!`
 

and go to the next level ( 3 in total ).
If it's not, You have folloving message:

 `'yes' is wrong answer ;(. Correct answer was no.
  Let's try again, me!`
  

4) notice that your answer must be "yes"/"no" or a sertain number - it depends from the description of a game. Also if you input any other string it will be interpreted as "no".

Each game launches by its name and have its own "question":

• primeNumber

  Question: 15

  Question: 79

  Question: 65,160,..,350,445,540,635,730,825,920
  Your answer: 

• makeBalance

  You have a number which you need to "balance": balanced number is a number where numerals differ from each other by 1 or are equal: 4455, 2233, 56, 777 etc. So if You got, for example, 4181 your answer should be 3344 and so on:
