Here's your bonus hidden puzzle:
I have a card in my pocket with the numbers from 1 through 48 written on it.
Some of the numbers are red, some are blue. They are arranged in a grid like
this:
14 25 8 ( 1) 4 5
41 ( 6) 35 30 (27) (26)
(29) (18) 47 (42) 39 (38)
21 32 ( 3) 10 ( 7) 12
(34) (23) (40) (45) 48 (43)
( 2) 37 20 (13) 16 17
( 9) 44 (15) 22 (19) 24
46 (11) (28) (33) 36 (31)
The numbers in parentheses are red.
