are the letters interchangeable?

Interchangeable with what? If I'm reading this correctly, and that you're asking about interchanging between the different leapfrog systems, then I believe the answer is yes. My sister has the one like this for the fridge, and its letters fit into the one my kid has, which is one that comes with a bucket. Does that help?

You can spell any appropriate three letter word on this device. Letters from any Leap Frog magnetic spelling toy (like this one or a different shape) will work. I had some left over from another different shapped one that I was able to use on this item. You can also buy replacement letters on Ebay or from Leap Frogs website. Hope this helps.

Careful, I've heard the letters are a new size in the newer products and are not compatible with older sets.

I don't know. We only use F. & it was a gift for my kids. But I'll bet you could use both--one or the other

If you don't mind one of the "o"s being a lower case letter and the other, a capital letter, then yes-you can.

If you are referring to another interchanged writing portion as shown in the photo, then the answer is yes.

Yes. There is a key on the left lower part of the keyboard that allows you to use umlauts and all other Non-English accents.

No, the game is in English. There might be a way to change it if you want to, but I wouldnt know how.

I believe that the pieces are interchangeable. I purchased this piece and it worked well.

I believe so. But not all are used in the puzzles. I don't think any of the words use the Z or the Q.

Yes. Kind of. See this thread for the letter distributions.http://boardgamegeek.com/thread/459128/letter-distribution

Do you have the letter H? And do you have a small K and R, I would like to have 3 letters total --small k&R; large H

I believe so. Most printers add extra letters after the original name because of a slight change that does not normally affect the hardware

Yes. If I recall correctly, it also has extras of some of the more commonly used letters (like RSTLNE)

Yes, there are double letters. In fact I pulled 5 blocks out of the box and three of them have E's. This would be a good question for Mensa!

Yes, they are interchangeable. As far as I have been able to research they are the same company.

When I searched the first part number, I came up with both numbers on amazon.com; the last one was about 3 times as much. I think that they are interchangeable. Sincerely, Wiley Henson
