Why server side games generally can’t be hacked ?

OVERVIEW:

• The Server – This party is responsible for serving content.
• The Client – This party requests content from the Server, and displays them to the user. In most cases, the client is a web browser.
Each side’s programming, refers to code which runs at the specific machine, the server’s or the client’s.
Server Side Code –
Server side is the code that resides at web server.
For every client request code is executed at server side and result is send to the client in simple HTML format.
Performance is lower than client side code due to server round trips.
Client cannot see the business logic though it is stored on server.

Client Side Code –
Client side code is reside at client’s browser itself. It is executed at
client side only. User can easily see the code by View – > Source option.
It is generally used in validation form like text field is empty or not, email address validation etc. It is faster than server side code
Server side code is responsible to execute and provide
the executed code to the browser at the client side. The executed code only have the
values or the results that are executed on the server.
There are many programs out there that claim to be able to hack games such as Clash of Clans, these are all fake, here’s why:
Any so called ‘gem hack’ will not work because the data is stored server side, so editing the data client side will then need to be confirmed server side.
In other words, there is no way to hack such a game. If there were a way, somebody would have figured it out, spread the information, and then it would have to have been patched rapidly. These kinds of games are specifically designed for people to not be able to hack into them. In order to do so you would have to gain access to the server and alter the information that contains things like how many gems you have. This in itself is a near impossible task because this information is sensitive and secure. It’s like if you were trying to gain credit card information off of a website like Amazon. It’s extremely unlikely and illegal that you’ll find a crack, but leaks do occur from time to time.
