Powerful but simple user interface

The user inteface minimises the effort required to work on puzzles and
lets you concentrate on finding the solution. For example, at any time
a single mouse click will pop-up the possible combinations for any row
or column. And they are always up to date, so you don't have to remember
them or use tables.

You can colour cells and candidates to help identify
patterns. Inconsistent or incorrect answers can be shown as you set
them and all moves can be undone. The solution for a single cell or
the whole puzzle can be shown at any stage. You can select the hint
which is easiest to understand or the one which removes the most
candidates.


Hint algorithms

Candidate Bounds, Unique candidates, Possible Permutations, Isolated
Necks, Hidden Singles, Hidden Pairs, Hidden Triples, Naked Pairs,
