-Overview
CS:GO is a FPS (First Person Shooter) game created in 2012 and is still one of the most played games on steam.
You pair up with a random team as terrorists (T) or counter terrorists (CT) and work together in several diffrent game modes to stop the other team.
As the terrorists in most game modes you have to work as a team to get to a bomb site (Site A or site B located on the map), plant your bomb which a random player from your team will get at the start of each round and detonate it.
As counter terrorists you have to stop the terrorists from planting the bomb, by waiting until the timer runs out, or by killing all of the enemy team.
-Game modes:
Deathmatch - Pick if you want to be T or CT and jump into a match to just kill as many of the other team as possible in 10 minutes.
All guns are free in deathmatch and can be bought in a short amout of time after spawning/match start.
after the 10 minute clock runs out the match will be over and show the top 3 players with the most points as the winners.
War games - 3 mini game modes to play for fun in the game:
Arms Race - kill each other with a random gun and get new guns by killing other players, 2 kills levels your up and gives you a diffrent gun.
Who ever reaches the top rank,gets the golden knife and then kill someone with it is the winner.
Demolition - Work as a team to plant a bomb or to stop the enemy team from planting the bomb, in this mode there is only one planting site.
Flying Scoutman - Eliminate your opponents  while having high mobility.
Casual - The classic CS:GO game mode, work as a team to eliminate the enemy team or plant/stop the enemy team from planting the bomb.
Wingman - Basically like a mini competitive game, group up with a small team to eliminate the enemy team or plant/stop the enemy team from planting the bomb.
About competitive we will talk about in its own session.

-The steam market,Trading and Gambling

CS:GO is problemly the game that the community uses the market for the most.
Some skins can be worth hundreds up to thousands of dollars, which made the community make Trading,lotto and gambling websites for skins.
There are a few ways you can throw some money and try your luck:
Crates - you acn get crates as drop items from games,or buy them from the market, and then buy keys to open them.
A case key costs around 2.5$ and crates up to 0.25$ on the market.
You can get from cases skins for diffrent guns from diffrent collections.
You might get a skin thats worth 0.1$ or a knife which can cost up to 1500$!
Personally I wouldent reccomend opening cases, its a waste of money and 99% of the time you will get worthless skins.

Gambling - The community of CS:GO has created quiet a lot of website where you can gamble in so many diffrent ways like a real casino.
Some websites have created thier own cases where you throw some money and open, such as skinhub.
Or websites where you can gamble for real,in real time between people,coin flipping, betting skins,etc.
Also personally I wouldent reccomend
