Games
If you are looking for chess games played in the club, then please see the Events page, this page talks about games in general.
Players can play as many games as they want in the club. A maximum of 100 simultaneous games is a general setting to avoid overloading.
Many games run simultaneously by each player.
Games can be divided into three groups in the club. These are all standard chess games, all the rules apply, but some of their attributes are different according to which groups they belong to.
The following table shows the attributes of the games belonging to the three groups:

ELO Rating
An ELO rating is the result of statistical calculations designed to measure the playing strength of players. These methods were developed by Arpad Elo and are named after him. The ELO system is in almost universal use and has been further refined by others, notably Glicko, but is still named after its creator.
In devising the ELO scale, some premises were used that are worthy of note. It was decided that a rating of 2000 would be the equivalent to scoring 50% in a US Open Championship. It was also decided that a player's rating would never be negative.
Importantly, the standard deviation was fixed at 200 points. This means that if a player's true strength is 1500, he will score around 68% of his results within the range of 1400 to 1600 (as measured by performance formulae).
Another result of fixing the standard deviation at 200 points is that it also defines playing categories. For example, most International Masters and Grandmasters are in the 2400 - 2600 category, most national masters in the 2200 - 2400 category. Those in the 2000 - 2200 category are called Experts, or Candidate Masters.

FEN Support
FEN is the abbreviation of the Forsyth-Edwards Notation, and it's fully supported in the club.
A FEN text contains one single textual line, which describes a setup of a game, and some other things about it.
In all the details please see here.
We can use FEN lines to start a game from a defined setup.
