Su Doku Puzzle

Hi All,

I have just uploaded a Su Doku puzzle workbook to my site.

The workbook will generate puzzles as well as solve them.

Any feedback is welcomed.

hi Andy,

i think yr game is great, but a tad too difficult
especially at the last empty slot

maybe you can add on a lifeline or two, like reveal one slot to make it easier but some points will be deducted....

he he, guess i'm too impatient for this game

Hi xlite,

I'm glad you like it.

Here's a quick fix for the less patient game players :lol:
It will create puzzles with fewer empty slots.

Code

' In the routine m_GetStartingGrid
' adjust the reveal number.


' current values
'        intReveal = m_GetRandom(2, 5)       ' number of value to reveal within subgrid


' new values
        intReveal = m_GetRandom(5, 8)       ' number of value to reveal within subgrid

Hi Andy,

This is great.

I haven't fully digested all of the code yet but it looks to be up to your usual (high) standard.

Good job. :thumbcoo:

Re: Su Doku Puzzle

Thanks Richie.

One thing that has been pointed out to me is,
When generating random puzzles there maybe more than 1 solution :yikes:

Obviously this is not correct for a pure logic puzzle. Sure you may have to guess when a particular cell could hold more than 1 value but the wrong guess should result in a grid that is unsolvable.
Currently cells can be swapped. The solution is still a valid complete solution BUT it may not tally with the solution the game is checking against.

I will have to do some more thinking on how to determine a single solution starting point without giving the solution away to easily!

This is excellent.

I'll never get any work done now.

I looked at the change for altering the difficulty level but couldn't find a line with the original values quoted. Have things moved on since then?

I think a good tweek would be to alluw the user to select a difficulty level when generating a new grid.
