yup, got the new e-mail too. new (and working!) code and all! fun but hard game!
so, if yu havent received any code yet, mail nintendo!!

nope, NEVER even got the e-mail.

Finally! Just got mine. Took 5 days but at least its here now.

Finally got my code. This game's pretty good!
@nason did you click the banner on the club nintendo page? It was the reason i never got an e-mail.

I didn't get an email, in fact I didn't get an email confirming that I had registered my games from Club Nintendo, despite registering Starfox and 3D Land. I've emailed Nintendo twice and had no reply.

Go to club Nintendo and log off and then in again. There should be a message on the side basically asking you to click there to confirm your email for the code. Put in your email and they will send you a confirmation email saying your code will come soon.

I can't register my Tetris 3D? Iv sent an email to Nintendo UK but by the time they get back to me It will be February and I wont be able to register and get my code! What do I do?

@3DS the code HAS to be in capitals.
Does it give you an error such as "Game has already been registered"?

Still haven't gotten my code, and I registered my two games on 26th of december. I'm getting frustrated now. (And got the confirmation e-mail)

Nah the game is brand new and I put it all in caps. Says the code is invalid

My codes still aren't here even though Nintendo confirmed it :/

@110. 3DS
When attempting to register your Tetris 3D game, have you tried entering the number "zero" instead of the letter "O", or vice versa, or mistaken a number "1" for the letter "l"? I have occasionally been caught out that way when registering a game.

@106. Geonjaha
Thanks for that tip. I finally found the link to submit my email address - it was there this morning without needing to log in twice. So I have now received my email confirming that I will receive the download code within a few days.
Let's wait and see

Tried that and the code still ain't working

What region is the game?
I assume UK.
If not Nintendo mistyped the code.

Bought it from UK from http://www.game.co.uk/
anyway I'll wait for Nintendo to get back to me about it. Hopefully there will be a way to fix this by the end of the month!

@3DS Ok, I hope the problem gets resolved.

Hopefully people still waiting get theres soon. It's my favourite 3D-Classic so far. Ironically it's one of the few things on the eShop I would have paid to get.

Nintendo emailed my code today, and I've just downloaded the game now.
Hope everyone else gets the same soon

Is it just me that STILL hasn't received the code? I've already e-mailed nintendo twice about it (a week apart) with no replies. I guess I'm not going to get it :X

I haven't received mine but it hasn't quite been a week yet.
Hopefully I should get something within the next couple of days.
