What is Rank and how does it work?
- First, your rank is NOT your score.
Also, your score is not your rank, but they are related. If
your rank is 60%, this means that 60% of the players have a worse
average score than you and 40% of the players have a better average
score than you.
idea of a rank system is to be able to tell quickly and easily how you
doing relative to the other players. When you make a Maj, you get a
score as per
the standard scoring of the NMJL. This is covered on page 22 of "Mah
Jongg Made Easy"
If you lose a game, you lose score as per the standard scoring. The
online game provides
these numbers in Options for you to see but not other players. If your
total score was
shown in the waiting room, it would not be very helpful. Here is an
example of why.
Say a player wins more than they lose and plays 20 games winning about
10 points per
game. This means that the total score would be 10*20 or 200 points. Say
another player plays
about the same but plays 2000 games. This means that the total score
would be 10*2000 or 20000
points. Now both players are about the same as far as skill level goes
this is not reflected in
the total scores. Ok, maybe we could use the average scores to compare
players. In this case, both players would have an average score of 10
points/game and so this is a good comparison.
So if you were used to average scores, this would work but you must
first play enough games (100)
for the average score to make sense. Also, most players would not be
able to make sense of
the numbers. Is 9.2643 a good average? Is -10.432 a bad average? About
the only thing that
can be said, is that if you have a positive average you win more than
you lose and if you
have a negative average you lose more than you win. Better than total
score but not very
helpful. Ok, so why not place all the average scores in order and rank
them? So if you had
12 players you would have something like -12.23, -10.32 -9.99, -5.43,
-4.44, 0.023, 0.99,
2.32, 4.42, 6.63, 9.45, 12.42. These are from lowest to highest average
scores. And now you would rank them 0 thru 12. This means that if you
have a 4, then you are 4th from the bottom.
This is starting to get there, but now you MUST know the number of
players at that instant
to make sense of it. Not very pratical. So the last thing to do is
convert your rank to
a percentage. So in the example, 4/12 * 100 = 33.33%
This is a very easy number to glance at and know how you are doing
relative to other players
at that INSTANT only. Please note: Rank is computed at the end of every game and
not just the game you are currently playing.
how do you use rank? If you want to play with players of about the same
skill level (not speed)
as yourself, then play with players of about your same rank. If you
to have a better chance of winning, then play with players of lower
rank. If you want a challenging game, then play with players
of higher rank. If you want a game that is 10 minutes or less, then
you need to be in the Timed room.
is an Exit Percentage and how does it work?
you exit a game abnormally, i.e. not using the "Back to Lobby" button, your exit percentage increases.
The exit percentage is calculated based on all of the games played in a season, so if someone
exits abnormally a lot, then stops doing that, over time and more games played, his/her exit percentage will go down.
idea of an exit percentage is to keep track of how often a player exits a game abnormally. The higher
the exit percentage, the more likely the player is to exit a game abnormally.
Note: Occasionally a player will encounter a problem that forces them to exit abnormally.
This is accounted for by not displaying exit percentages lower than 1 percent.
how do you use the exit percentage? You must evaluate another player's exit
percentage and decide for yourself if this person will be fun to play with.
What is Completion Percentage?
Completion Percentage is defined as 100 - percentage of games over the time limit.
This means the percentage of games completed that didn't time out.
Because this is relative to a timed game is it only shown in the Timed room games.
What are the differences between the waiting rooms - Social, Timed, and Official?
- Social Room:
- no score and no rank kept
- No time limit per game
- Contains practice tables (where you can practice the on-line game with "computer" players instead of
- Timed Room:
- Time limit per game (from 6 to 14 minute time limits depending on the table chosen)
- Offical Room:
- Offical - Plays the Official rules of the NMJL for nice friendly games
- No time limit per game as per the Offical rules of the NMJL
- Scored and Ranked
Note: In the official National Mah Jongg League rules there are no time limits for games.
What is the Timed room and how does a time limited game work?
When a game starts one must first click on the box by their name (see Instructions page).
A player agrees to 3 things when a time limited game starts:
1) That they are ready to start the game.
2) That the player agrees to the other 3 players and would like to play with them.
3) Since this is a timed table, that the game will not last longer than the time limit as selected by the table number.
It is a players responsibility to make sure they agree to the above 3. Once the game starts, if a player says anything about the speed or pace, this means THEY made a mistake and did not select the correct players to play with. (See 2 above).
If a player makes such a mistake, they should simply complete the game and NOT make the same mistake again. They should NOT complain or harass the other player as it was their choice.
Another point is that ALL games in ALL rooms and at ALL tables play at exactly the same speed. This means that if one is worried about the time limit of a game, one should select a larger time limit or no time limit in the Official room.
is my "Net" time and why is it high?
net time is a measurement of the time it take for a message to go
from the game server to a player's computer and back in seconds. When
you are in the waiting room and you type /p in the chat box, the system
will tell only you your net time in seconds. When you are playing a
game and type /p in a chat box, all 4 players' Net times are shown.
following are some of the reasons that net times can
When your computer connects to the game computer, it first connects to
your ISP (Internet Service Provider). It then connects to another
machine in your ISP's local network and continues with this until it
connects to the Internet. Once it connects to the Internet, it connects
to machines which cause the connection to work toward the game machine.
This "routing" is done to make the connection fast and doesn't have to
do with geography. Finally, the connection is made to my ISP, which
then connects to the game server. This sounds like a lot of connections
and you are right. There are generally about 15 machines involved in a
typical connection. So why are some net times high?
- If a player has a slow machine or one with low memory or that is
running another application, it can cause the net time to be high. This
can be caused by anti-virus software also.
- If a player has a slow modem or a bad phone line or other hardware
problems this can cause a high net time.
- If your ISP has a slow server or congested server or a router problem,
then your net time will be high.
- If one of the 10 or more routers or servers in between has congestion or
a hardware problem your net time can be high. This can be caused by
something as simple as rain causing a local problem.
- If there is a hacker attempt on one of the machines in the connection,
this can cause a high net time.
- If there are is a power outage in one of the machines, then the
connection will have to be rerouted and so the net time will be high.
- If there is a hardware failure.
I think you get the point.
How can one tell if the problem is just some connections or is it the
server that is the problem?
First make sure you are able to get to the web site. (This page is on
the web site). The web server and the game server are on the same
When you are in a game and you do a /p, are ALL of the players net
times above 1.0?
If this happens consistently over several tries, then it is an
indication that the problem may be with either the game server or the
game server connection. In this case and this case only, you need to
send an email as per the support page and let me know.
This needs to occur in more than one game also. If this is not the
case, then some of the players have a slow connnection, due to many
As an example, if an ISP for some reason has a connection problem in
getting to the nmjl.org game server, then ALL of the ISP's players may
have this problem. Since it is the ISP that may have the problem, I
can't do anything about it.
Okay, so what can be done about it?
Most of the time the problem is much bigger than just this game and
it will resolve itself in due course. If you have a consistent problem with
high net times, you can call your ISP and see if they can determine the
cause of the problem.
If the problem is with your ISP and they are not willing to help
rectify the problem, then you might want to consider a new ISP.
If it is determined that the problem is with the nmjl.org game server
or its connection, then please email me and let me know and I will do
what I can.
