A wriggling worm is 5cm long. When it curls up it measures 1cm shorter. How long is the worm when it curls up?
Now, use this number in the following table to calculate the missing letter in the link:
1 2 3 4 5 6 7 8 9
a b c d e f g h i
AHA! It's a trick question. The worm is still 5cm long, its just curved now rather than straight! I'm on to your game, djmax2.
unfortunately rapieshare.de doesn't seem to have the file... Stupid math....
