I've tried this 8 times and it worked all of them....

can you figure out how it works ?

The number of symbols they require to deal with all numbers in the range 10-99 is very limited.

Consider a number written as xy; this number in value is 10x+y
Next you have to add up both digits (x+y)
Then subtract it from the original number.
So you get
10x+y - (x+y) = 9x

So many numbers will fall in the same category:
all numbers between 11 and 19 all yield 9 (11-2=9, 12-3=9, 13-4=9, ...)
all numbers between 20 and 29 all yield 18 (20-2=18, 21-3=18, ...)
...

Most of the symbols are never needed, so can be chosen at random.

rofl! I didnt really need an answer, but I like your detailed explanation
We used to play that as kids (only with cards instead of simbols), the swf version looks cool and its fun to see ppls reactions to it

[VJ]

Judging by the reactions, it looks like I spoiled the thread for other people...

Sorry...
