We know. good job.
Report as
How do you get that?!?!?!
Report as
Wait for it. sgrandquist will explain all in about 5 minutes.
Report as
I know, but I really wanna get it myself!
Report as
Thanks Sarah.

Sarah is right,
The answer is 2 because of the number of closed circles in the numbers Eg: 0,6 & 9 have one & 8 has 2.

THANK YOU ALL FOR PARTICIPATING

I get it!!!! I would never have gotten that!

Notice that none of the "number codes" includes a 4. Different fonts can have it opened olr closed, so it is best not to use the number 4. The answer can be 4, just not the clue.
Report as
True, thanks.
Report as
Two can also be written with a loop.
Report as
Thanks, didn't think of that one also.

Thanks for your input. If you are up for some more, I will post some tonight (Aussie time). In about 7 hours from now).

Take care,

9 is 1, 8 is 2, 7 is 0, 6 is 1, 5 is 0, 4 is unknown, 3 is 0, 2 is 0, 1 is 0, and 0 is 1.
Add the new value of each digit in the number. 2581 = 0+0+2+0
