How to Catch All the Unowns in Pokémon Diamond/Pearl/Platinum

Reviewed by Ishrak

Last Updated: September 30, 2025

While catching all the Unown forms A-Z doesn't have many advantages, it's still a great way to finish off your Pokémon game. You can show an Unown to a boy in Solaceon Town to get capsule seals, or just catch all of them to get Unown forms ! and ? and to see the Ruin Maniac finish digging the tunnel.

You'll have a lot of them soon.
Check these off one by one as you capture each letter.

To get there, go above the house above the Pokémon Center. From there, head right until you can't go any further. Jump over four of the ridges, go right again, and enter the Ruins.

Understand the layout of the Ruins. There are seven levels to the Ruins. Each level contains a big room, two dead-ends, and a staircase to the next level.
- The first big room has no Unowns, the second has "F", third has "R", forth has "I", fifth has "E", sixth has "N", and seventh has "D". Needless to say, these particular letters will be the easiest to find.
- The dead-ends contain the rest of the alphabet. Check each individual dead-end four times each to quickly catch as many letters as possible.
6
Visit the Ruin Maniac once you've caught all the forms of Unown. The tunnel will be finished, and there will be two more Unown to catch (! and ?).
- Once the tunnel is finished, it should connect to the ruins.
7
Enjoy.

Question

How do I get free master balls in Sinnoh?

Community Answer

You either have to cheat or get another game and continue to transfer master balls over from that game. To do that, you will have to restart the other game every time, but in my opinion it isn't really worth it.

Use your Itemfinder throughout the Ruins; there are several buried items.
