BlueBlocks is the first real multiplayer Bluetooth game for PalmOS. It uses a so-called piconet to connect up to four palm PDAs into a bluetooth network. These four palms can then join each other in a multiplayer session of BlueBlocks.

The game has been developed and tested with a PalmOne M515 and a PalmOne Tungsten T. Tests have shown, that the old PalmOS 4 based machines have problems with piconetworks and sometimes drop an active piconet connection. It is therefore recommended to use newer Palm OS 5 machines if available. If Palm OS 4 machines are to be used, they should be used as client devices only. Clients are the devices, that actively connect into the piconet.
