    Project: Take-Away Game
    Standard: 91883 (AS1.7) v.1
    School: Tauranga Boys' College

    Python: 3.5
-------------------------------------------------
This program plays a takeaway game. The program asks how many players are amongst them, name themselves, tell how many rounds they would like to play, and then the game starts.

The game consists of you taking 1~3 "chips" from a pile of 21. The winner of that round is the player that takes the last one (the 21st one), leaving none remaining in the pile.

This code allows for players to customize their experience a lot, allowing them to state how many players, as opposed to a standard game where you are limited to two.

The main caveat with this game is that Player 1 in a 2 player game is always guaranteed to win. They can accomplish this by always aiming to change the chip amount to a multiple of 4, securing the win.

There is no way to circumvent this flaw, as the only solution, that being changing the number of chips to an unknown number, would defeat the purpose of the game, therefore not being a sufficient solution.

Despite this disadvantage, this game is very fun if people do not realize this specific strategy, allowing for a fun experience from all players.

Do you follow the rules, or do you give in to the urge for more, knowing that it's a moment that could go unnoticed?
