In the external program section you will find 2 trapper chess door games. the one in TrapDoor Games is a stand alone original game built by trapper for chess lovers. The 2nd trapper chess you will find in Shift-Bits Games. Zofrag has built an amazing set of games that all work together through a program called the Exchange. Trapper chess has recently become part of that system, where you earn credits for playing which then can be traded for other items at the Exchange for use in other games within the system. trapper chess plays exactully the same, just for resources instead of bragging rights. Which ever you chose Trapper (The TrapDoor BBS) and Zofrag (Shift-Bits BBS) wish you luck, and we hope you have fun playing at these fine systems.
