Logic Problems X2 |
|
February, 2007 marks the 5th anniversary of our joint puzzle project -
Logic Problems (Monthly Interactive & Printable). Because of the event
we've prepared an extra addition to our traditional bonus Logic
Problem which we publish each anniversary. We decided to convert our
first 24 Logic Problems to the printable format and present them in
two special PDF packs. This is the second one consisting of 12 Logic
Problems published on our site five years ago. Do you still
remember?.. |
