wetware: Thank you, i didn´t remember where it was. I think it´s not the best place and it seems a little confused. In the cube games the score is 1,2 and 3 for a normal win, gammon and backgammon and in the triple gammon system is 1,3 and 5. Maybe i think it could be explained much better.
Rules say: "The other player gets a bonus of 2 points and 1 point for each own frog which was not found by the opponent." I don´t understand this. ¿¿2? or ¿1? points?
Fencer: I vote for: Backgammon Cube 7 points Hyper Backgammon Ludo Dark Battleboats Cloned Backgammon Linetris (never played in teams) Spider Linetris (never played and more balanced than Spider Line4) Dark Chess (never played too and it´s not necessary a great level) AntiCheckers (easy and fast game) AntiReversi (interesting variant) Halma 10x10 (nice game) Tablut (very interesting) Portuguese-Spanish Checkers Atomic Chess (funny game) Knight Relay Chess (never played) and other 6 games more.
Rui Carvalho: When the tournament starts. If you want you can play games in "Waiting games" ("Jogos em espera" in portuguese) You can get more help in the portuguese forum http://brainking.com/pt/Board?bc=80
tarcellius: Welcome to BrainKing! I´ll try to help you. Stairs is only for paid memberships. As free user (Brain Pawn) you have a limit of 20 games at the same time. The limit of the tournaments is one for you. You can accept a game in the section "Waiting games" or you can put your own game in the section "New game" For getting a rating you need to finish 4 games of one type, at least. Read the FAQ section, you´ll find an interesting information there.
Gentlegiant101: I just exposed a simple question. About your history, i inform you the time conditions of your game were 7 days for all it without weekends, so you lost this game because you spent all your time before of the end of it.
I propose negative points! For example: -100 for users who don´t move in position with only one legal move -500 for users who don´t move in a loss position -1000 for users who don´t move in a loss position and with only one legal move
Tuesday: You can excel at anti-chess (and chess too, why not) but having not knowledge about chess is not a help for playing well antichess. There isn´t a logic relation between "i am bad at <gameX>" -> "i am good at "anti<gameX>" This implication is false (generally) It´s just a matter of practice. I´m sure you could play very well, play and learn.
TexasToest:
Time per move and vacation modes # Fixed weekends only - if a game is created with this option, the player's weekend settings are ignored and the standard Saturday-Sunday weekend is used. Moreover, no other vacation days are calculated for this game time. Such game invitations or tournaments are marked by a green dot.
# No days off - this game is played with absolutely no days off and the time range between moves is never longer than the defined days/hours per move value. Such game invitations or tournaments are marked by a red dot.
Marfitalu: It´s correct. Check the profile of MrLoupCity. He has all days until 3 of January as vacation because he has monday and thusday as weekend days and he still has vacation days. The other game, i can´t see it but it can be the same situation.

Doerdich:
The formula Fide for variation of rating is:
NR = OR + (SG - SW) * K
NR is New Rating
OR is Old Rating
SG is Score Gotten
SW is Score Waited
K is a Constant
K can have three values :
K=25 when the player hasn´t finished 20 games
K=15 when the player has finished 20 games and his rating is lower than 2400
K=10 when the rating of player is upper than 2400
Score Waited is calculated with a list of percentage, but you can calculate approximately in this way :
SW ~= 0.5 + [(RP - RO) \ 800]
RP = Rating Player
RO = Rating Opponent
The highest value of [RP - RO] is 350 and the lowest is -350. If the different is higher than 350 or lower than -350 then we have [RP - RO] = (+-)350
All this means that the highest variation can be:
Rating Player = 2000
Rating Opponent = 1500
Different above to 350
Score Waited ~= 0.5 + [(2000 - 1500) / 800] =
= 0.5 + [500 / 800] =
= 0.5 + [350 / 800] =
= 0.5 + [0.4375] =
= 0.9375
If the player rated 2000 loses the game then
New Rating = 2000 + ( 0 - 0.9375 ) * K =
= 2000 - 0.9375 * K
With K=10 => New Rating is 2000 - 9.375 = 1990.625
With K=15 => New Rating is 2000 - 14.0625 =
1985.9375
With K=25 => New Rating is 2000 - 23.4375 = 1976.5625
The highest variation is (+-)23.4375 for players with rating lower than 2400 and no more of 20 games and for strong players is only (+-)9.375

I don´t know much about how works ratings here but it´s not very similiar to the system of the federation international of chess (Fide) based on the method of the mathematician Arpad Elo.
I think the rating initial (provisional but initial) in brainking is established after of the fist game finished using the rules of the system of US chess federation [http://www.sizes.com/sports/chess_ratings.htm]
This system works in this way
rating initial = rating opponent + {400(win), 0(draw), -400(lose)}
However Fide system is different :
rating initial = rating opponent + {12.5(win), 0(draw), -677(lose)}
The variation of rating in the second and next games works different too.
This system applied here favours to the players win his first game. If you win the first game against an opponent of 1900 then you will have 2300 as an initial rating and you can keep this rating playing against weak players

Grim Reaper: Sumerian has only 29 counted games because three losses are by time out in one or two moves, so his score is +28=0-1.
The reason of Sumerian is the top of Gothic is the same by you are the top (very) provisional of chess : few counted games can be enough for get the highest rating.
Maths are beautiful!!
