Technical Support

General Support

Q: How can I play the games if I am behind a firewall?
A: Many companies and organizations restrict access to outside data using a "firewall". A firewall is a set of policies that permit some activity and deny others; this is accomplished through software installed on the organization's networks. If a company only permits activity for duties they perform and know about, they know they can feel safe keeping the Web ports open.
If you try to play one of our games and the game software on your computer is unable to connect you to our game server, you will see a blue notification box telling you that you might be behind a firewall. Try selecting the option that says, "I might be behind a firewall. Try bypassing a firewall once." This will set the game software to connect you to our game server using the same port as your internet browser, which should get through the firewall and allow you to play the game.
If that works for you, then you can set the game software to always bypass your firewall by selecting, "I am sure that I am behind a firewall. Always connect bypassing it." This will prevent you from seeing the firewall notification in the future.
If you try to bypass the firewall and are still unable to play the game, then you may need to try turning off the firewall software (if you are on a home computer). Or, you may be experiencing a different issue, such as a problem with your internet connectivity.

Q: I keep losing my connection. What should I do?
A: There are a number of reasons why you get disconnected from the game. MahjongTime has fast & underutilized servers & a direct internet backbone connection via an extremely fast 100 Mb/s full duplex lines.
Depending on your location, however, there can be up to 20-30 intermediate networks that connect you to NAMF server - each of them is a potential point of an 'occasional' failure. Although it is quite rare, but Tier 1 network has short term outages as well.
To minimize the chance of a disconnection, when you are playing avoid, whenever possible, downloading files, receiving mail, using VoIP phones, or other bandwidth-consuming applications. The fewer applications you are running, the better.
The best connectivity test can be achieved with a shareware product VisualRoute available from To test all the intermediate networks go to this page: and type for the server address this IP:
Note that the quality of your connection to your ISP, the quality of their connection to the internet backbones, and the quality of all paths between them and NAMF will have an impact on the speed of your connection.
If your connectivity is less than optimal for your modem speed and location, then somewhere on the internet — between your computer and the NAMF server conditions are less than optimal

Q: If my connection fails, am I kicked out of the game?
A: Yes, you are. If it happens simply re-login and re-join the game. When you are disconnected, our game engine will wait for you to reconnect for certain amount of time, and will make a move on your behalf when the time expires.

Q: Will cordless phone interfere with wireless internet?
A: The answer is yes. It can if you use a 2.4 GHz phone. This is the same frequency as your wireless router. It probably will not be noticed unless you have a lot of other things interfering such as satellite dishes and some remote controls also. Plus if you have a lot of other wireless in the area. It can cause problems as well.
More and more households and businesses today use cordless phones, made by a variety of companies. Cordless phones operate on 3 different frequencies, 900MHz, 2.4GHz, and 5.8 GHz. Do those last two frequencies sound familiar? Yep, at least the 2.4GHz and 5.8 GHz frequencies fall in the same frequency bands as 802.11b and 802.11a wireless LANs, respectively -- and the use of the phones can cause significant interference to your WLAN.
Potential 802.11b Interference
The majority of cordless phones in use today are 2.4GHz models. These phones, innocent as they may seem, reap devastating effects on 802.11b WLANs. There are cases where 2.4GHz phones severely interfere with 802.11b. Some 802.11b WLANs have even been totally shut down by somebody simply answering a 2.4GHz cordless phone.

Resolutions to Consider
What can you do to eliminate the effects a cordless phone has on your WLAN? There are a number of solutions, some of which are guaranteed to work and others that may significantly lower the interference level. The fail-safe solutions all consist of replacing equipment.
If your interference is coming from a 2.4GHz phone, the sure fire solution is to change to a 900MHz or 5.8 GHz phone or switch the WLAN to 802.11a. Both methods will eliminate the interference. These solutions are the most effective, but also the most expensive.
Before spending lots of money on new hardware, consider the following less expensive (but possibly less effective) approaches:
  1. With 802.11b systems, try changing the channel on the access point (at least try 1, 6, and 11). Anecdotally, people have found that they have the least interference on channel 11.
  2. With 802.11a systems, change to any one of the channels that are not in use by the cordless phone.
  3. Change the location of the access point or the cordless phone base. Maximize the distance between the cordless phones and WLAN devices, especially WLAN users operating on the fringes of the access point range.
  4. If you have the option, use an external, remote antenna on your computer. This will let you place the antenna as far away as possible from a cordless phone.
There are no guarantees that these actions will work, but they may cut the interference enough to allow acceptable performance. The most attractive aspect of these solutions, however, is the fact that they are free.

Game Errors

Q: The system always tells me that I've already moved or it's not your turn? What can I do?
A: The system can move your tiles if you do not discard your tiles on time. The best solution for this is to play games with higher time limit. In most cases it solves the problem.

Q: What does it mean when I get a message that says "connection timed out"?
A: This usually means that you have lost the internet connection. Simply re-login and re-join the game that you are currently playing.
