On-line rating (discussion)

1. Points should definitely be deducted for losses; otherwise, it will become a cumulative system where the person with more free time, and therefore more games played, has a higher chance of becoming the leader. IMHO.

2. A fixed number of points should be added for a win and deducted for a loss.
3. And then, based on the results of a certain period, a bonus/penalty should be awarded to everyone according to the results of the duels... let me explain:

+2:)

Will there be a limit on the number of games, and if so, how?

There should be no limit on the number of games. This isn't a tournament; it's just regular online games, albeit with certain rules. And most of the rules should be able to be changed by mutual agreement between the opponents. For example, you could set a turn limit of 4 minutes, but if both sides want, you could set it to 10 minutes. :)
By the way, if the ranked games do cross the line and become more than just a discussion, it would be good to vote on the most important points, such as difficulty, map size, and turn limit. I'm in favor of 4 minutes, 160%, L+U, no water, no AI, strong monsters.

The obligation to play with all participants and the scheme for the sequence of choosing an opponent.

This is, IMHO, one of the problems. It will be very difficult to implement. There is a possibility of manipulating the rating by playing only against "weak" opponents. It will be necessary to require playing against different opponents. But I don't know how to do this. Because it's possible that someone will have many games with the same players not because of rating manipulation, but simply because those opponents play according to rules that suit both of them. For example, I will prioritize players who play at 160% difficulty and with a turn limit of at least 4 minutes. I'm unlikely to play with those who only play at 1-2 minutes and don't want to increase the turn time.

Forgot to add that the "speed" of winning against an opponent should either not be taken into account at all or be taken into account as a secondary factor (e.g., distribution of places in case of a tie in points), but it should not affect the number of points/bonus in any way.

This will encourage dragging out the game when the situation is already hopeless, which is not good for online play.
