Remember, WGT can't fix Adobe Flash, which has been a flawed computer program format for gaming for years. I'm sure the techs here do their best and do read complaints, so cut them a little slack, as they are at the mercy of Adobe with each new version released.
Here is the latest Flash version (as of this post) 3/10/2016 – Updated debugger and standalone versions of Flash Player. These versions contain fixes for critical vulnerabilities identified in Security Bulletin APSB 16-08. The latest versions are 21.0.0.182 (Win and Mac) and 11.2.202.577 (Linux). All users are encouraged to update to these latest versions. This page linked below is the Adobe support page, which also includes all new downloads and debug info.http://www.adobe.com/support/flashplayer/debug_downloads.html .
The Google Chrome browser updates to the latest version of Flash if you have settings correctly checked in the Chrome browser, so there's no need to download Flash if you use Chrome.
Also, when playing with several players realize you may be connecting with people running different browsers, operating systems, computer software, platforms, PC and/or MAC, which causes issues in itself.
This game/or Adobe has a memory leak, forcing your PC's to allocate more RAM, especially during long matches. Here are some tools that have helped me avoid disconnects.
One: Make sure you are running the latest, proper Flash version. This page will show you what Flash version you have, and provide a how-to and uninstall previous versions (this must be done before a clean download)... http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html
Two: Memory Cleaner. There are several free one's out there so search yourselves. Just Google 'memory cleaner' .. This is the one I use, simple, small, safe and easy to use. http://www.wisecleaner.com/wise-memory-optimizer.html
Three: CCleaner. Safely cleans computer of garbage files and fixes registry errors. I've used it for years. The free download is fine. http://www.piriform.com/ccleaner/download
Four: Clean Master for PC removes junk and unneeded files that CCleaner overlooks. http://download.cnet.com/Clean-Master-for-PC/3000-18512_4-76174439.html
Five: Clear your Flash Player and check settings settings. http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager06.html
Six: The Chrome browser automatically updates all Flash components, and it works great for me with this game.
Seven: No matter what operating system or system platform, this article provides how-to, direct downloads for uninstallers for PC and MAC. http://bgr.com/2015/07/27/how-to-uninstall-flash-pc-mac-chrome/
Again, REMOVE OLD VERSIONS OF FLASH BEFORE A FRESH INSTALL. Do not just rely on the installer, as residual files are left behind on installs.
Test your computer's Flash capabilities: Flash Benchmark
http://www.snailsanimation.com/benchmark08_play.php ... The site runs Flash animations and measures how well your computer displays them. It measures how many Frames Per Second your computer can draw on the display. The more FPS, the better the animations look.

Another tip I've seen from players posting here include checking your firewall and DNS settings. Make sure you're not running two firewalls. Windows 10 wants to enable the Microsoft firewall, despite one you already have running, meaning you're running two firewalls, which is not needed. It's actually a default setting in Windows 10 that needs to be double checked to make sure it is off.

From WGT "System Requirements" thread, some other tips. http://www.wgt.com/forums/p/635/2552.aspx
Disable Popup Blocker
To disable your popup blocker, follow these instructions:http://www.wgt.com/forums/p/252/854.aspx

Close and exit all other applications
Make sure the browser with WGT playing is the only application running on your system. Also regularly running a program to clean your system of spyware and viruses will greatly increase the game's performance. Any application that uses your system's RAM (memory) or CPU will slow down your game.
Flash Storage Settings
Make sure your browser allows flash content. Go to the Adobe Storage Setting Manager by clicking here . Move the slider so that you are allotting at least 100KB to storing flash objects. Check the "Allow third party Flash content" and "Store common Flash components" checkboxes.
Security Settings
Make sure the security setting on your browser is not set to High. This may prevent you from viewing certain things on the site. Also, people who have CA Security Center installed on their computers have been known to have problems viewing the site. Disabling some of the features in the program seems to solve the problem. You can read more about it here: http://www.hallicious.com/2009/05/ca-security-center-browser-problems . Please note that WGT has not tested these suggestions and that you should follow them at your own risk.

I use all of these programs and fixes safely, they've never damaged my computer and I rarely have a game disconnect in match play.
