The Sudoku puzzle solver engine is written in C and deployed as a SIMPL receiver on the Linode. In this demo this engine is accessed via a Tcl/Tk client via the tclSurrogate TCP/IP protocol.
You'll first want to be sure that the Tcl/Tk interpreter and libraries are installed on the workstation you will be using to access this demo. Tcl/Tk is available for free download for Windows, Mac or Linux workstations.
Next you'll want to download the Tcl/Tk Sudoku client from here.
NOTE: If you have a particularly secure firewall which blocks both incoming and outgoing packets, you'll want to have the system admin give you outgoing access for packets destined to icanprogram.ca:port 8000.
You can run demo by typing:
A screen similar to this should pop up on your workstation.
Have fun. Hope you enjoy programming the SIMPL way.
