What our customers are saying

I have been having a great time setting it up! It is so user friendly that I can whip through the set up in no time! I am also thrilled with the options of the music, logo, etc. I think my class is going to have a great time with this and I will be able to customize it for many classes in the future!

I just want to send you a GREAT BIG THANK YOU!!

"I tried the software last week and people loved it. Quite a deal. I had so much resistance when I came up with this idea. There were people that refused to take part, but once they were there, got totally caught up in it. It was an excellent tool for review training."
"I just received my order for two of your classroom games. They are wonderful!  . . . Thanks for your help and for creating software to help keep kids motivated! "

Firewall or blocking peer to peer communication    
1. Sometimes a network will be setup in order to block peer to peer communication. This is exactly the basis of the smartphone - desktop connection. You will have to ask your network administrators to unblock this in order for your smartphone to communicate with the desktop computer, specifically the program.    
2. Sometimes a computer will have a firewall protecting it from the unauthorized access to the computer. A message like the one below will appear when you attempt to start one of our games:    
3. In this event, please click the <Allow access> button, in order for the game to communicate with the android device.    
Example of Firewall blocking communication    
ZoneAlarm is a free firewall blocking program. We use it on 2 of the machines in our offices. Despite our best efforts, on one machine we always have problems communicating between smartphones and the program that is running on the computer protected by ZoneAlarm.    
So here are the steps that we take to get smartphones connected to the program on that machine.    
1. We right-click on the ZoneAlarm icon in the tray: *    
2. Then we right-click on the "Snooze Firewall for 5 minutes . . ." *    
Of course, you may wish to turn off ZoneAlarm during the duration of the game, but please, turn it back on when finished with the smartphone enabled program.    
*Your screen will probably look different than this.    
You may mix the use of androids and iPhones as buzz-in devices.
However, we recommend that you do not mix the use of smartphones with any other buzz-in device, including buzzers, keyboards and gamepads!
