Excellent observation, Simon!

The error is in the display definition:
-            print " " + @s[a][b][c][d].to_s
+            print " " + @s[a][c][b][d].to_s

New output:

 2 3 9 | 5 4 8 | 6 7 1
 4 7 1 | 2 6 9 | 8 5 3
 6 8 5 | 3 7 1 | 4 2 9
-------+-------+-------
 5 1 6 | 7 8 3 | 9 4 2
 8 9 2 | 1 5 4 | 3 6 7
 3 4 7 | 6 9 2 | 1 8 5
-------+-------+-------
 1 6 4 | 9 2 5 | 7 3 8
 7 2 3 | 8 1 6 | 5 9 4
 9 5 8 | 4 3 7 | 2 1 6

Sorry, I shouldn't have opened that bottle of champagne yet!

Christer
