I like the idea of the trick. I like the construction of the trick.
As a magician there
are 2 steps to figuring out the number.
Step 1 was easy to master.
I have spend
close to 90 min practicing step 2. And when I say practice I me just trying to get the number
right, not doing the full patter. So I can do 4 or 5 numbers a minute.
I am still only
about 60% accurate, which is little better than a guess. 4/3 works for me but getting the 1/2/5/6
feels like I am just guessing.
Method 1 (in hand) is not something I can get to work at
all.
Method 2 (on a flat surface) only work for 1/6 on a hard flat surface. Will not work
on a pad or even a table cloth.
I have to agree with this review. I, too, have tried to ascertain the number using the methods Rick suggests and, yes, it does feel like I'm guessing nearly all the time, apart from knowing odd from even.
