Pokémon Gold and Silver/Ruins of Alph

The Ruins of Alph is probably the most mysterious place in the game, first go to the cave to the north, and start the puzzle, here is the solution:

Cave 1
The 4 pieces that look like they go in the corners do, there are pieces that have 2 lines on, these go on the outside too so it forms a white rig round the outside. Now for the middle, there are 2 squares with a big circle on them and in the corner a small quarter of a circle, these go on the top, these are eyes and the two left are the claws, if this doesn't work swap the two middle bottom peices around.

This will unlock these Unown in the passage- Unown are letters so they resemble: When you catch 4 of these and go outside, you will get an upgraded Pokédex
