Update:


Progress quicker than anticipated.
Random but solvable start mode now added (version 0413). Foreign numbers still available.

Thanks for valuable feedback @silverwarior


No plans to use iterative deepening algorithms for this project.
Got to start tackling the graphics /ascii art situation first.
That will be a task for next mini-game project . Which hasn't started yet.

Now time to enjoy some well deserved beer and cheese
