It's pretty much the same question I posted 15 years ago, still no answer!

If I can find the original firmware it may just be enough to reprogram it, I think I messed around with the T13 code at some stage.
I'm trying to stop my grandchildren "manipulating" the dices when we play monopoly, they always win. I may have a chance with the electronic dice...not that I would put any special code in it or anything like that...... 
It seems to me that, coming from you, a Dice Card with a fingerprint scanner built into the back side would be a dead give-away that the code wasn't clean!

I was thinking more on the lines of how many times you subtly click on the spin button or how long it is pressed for.
FWIW, what I do know is that to represent a dice display requires 4 outputs (assuming you run certain LEDs in series or parallel)
1 5
2 4 6
3 7
A = 4
B = 3+5
C = 1+7
D = 2+6
1 = A
2 = B
3 = A+B
4 = B+C
5 = A+B+C
6 = B+C+D
But I sure would like to see that schematic.
Monopoly. Always buy the Orange streets. Don't ask why but seems to win most of the time.

Of course there is a certain amount of luck involved. Perhaps you are a Jonah.

As an adult you can always make up the rules.

Doesn't work with them, they can read and enforce the rules. 
Anyway this thing must be made by the millions and sold to all the casinos around the world that's why is so top secret I guess.
Forget throwing dice, like this pianist did, you need to discover the next Game King software flaw. My wife always complained I spent too much time on Game King--little did I know I had been sitting at a potential bonanza.
The amazing story begins back in April 2009 when Kane – a virtuoso pianist with a penchant for Game King video poker – stumbled upon a very serious hole in the machine’s programming. There was a bug which had gone undetected for seven years,

IIRC* (I have a Monopoly set somewhere, but don't feel like digging it out) the only space to which you get sent is Jail. The orange streets (again, IIRC) are between 6 and 9 spaces from jail. Knowing the bell-curve nature of 2d6, and several people being sent to jail, you would have a large statistical advantage there.
Also @ kk6gm - I was thinking something like that too, but a) you beat me to it, and b) your solution is much more complete than mine. S.

John,
have you checked the links that pop-up when you do a google search on "avr dice board"
In the Images It pops up and also there seem to be a number of interesting links at first glance.
Yeah, I searched but nothing comes up for that board. Lots of dice code and boards around, I even have some code from our beloved Chuck Baird (RIP).
It is possible that I saved the original code from the chip but can't find it, maybe I need to power up the older computer.

to bad, the results looked promising.
Perhaps Morton could dig the Atmel Archives. It has to be around there somewere.
