In this case, the objects should always be in the same place, but the words should be random. The part with random words is fine with the shuffle function. 

But if I have 30 words/objects, and only want to use 10 in one gameplay, I don't see how that would work, besides stacking 10 on screen. But with the stacking technique, it would not work well to show 2 or 3 words at the time.

If there was a way to load the next word in the same spot, when one is hidden, that would open up for a lot of game activities. In this case, I would perhaps place 3 words side by side. If the user finds the object from a word shown at place 1, then a new word will show up there. And perhaps they find 7 objects from place 1 words, before they find the words from place 2 and 3.  If they were stacked, it couldn't happen this way. 

When the game loads, show random word in place 1, 2 and 3. If a word is matched with the right image, then hide the pair, and show a new word in the same place. Every word can only be shown once, and maximum 10 words must be used during a game. 

If an element in a group is hidden, then it's not possible for it to show up again in the same game, right?

It's still for the same thing; A match game.

I will make an illustration, and have objects on top - hidden in plain sight, that the user can find and click on.

To know which objects to find, they'll be provided with a textbox with a word in it. It could be hat, butterfly, red flower, squirrel and so on.

I want to show these words one at the time, or perhaps 2 or 3 side by side.
When the user finds one of the objects and clicks it, the object will be hidden and so will the word. The next word will then be shown.

Should it be more advanced I'd make 30 different words/objects, and only use 10 random words in each gameplay. But the way to do it, would be the same, I presume?

I could perhaps just stack the words, and when one is hidden, the next will be shown, but I'd like to be able to have a clean background for a moment in between the words, if possible. If not, I'll just stack them.

But I think the other way would be the best, and could be used for quizzes and other games too.

I'll take the quiz thought:
If I would make a quiz with 500 questions, and let the user play a game, where only 10 of these questions should be used. How would I do that? It's the same thing, really.

Or perhaps you have a better solution, that I haven't thought of yet? I am not totally familar with all behaviours yet, so if I'm going the wrong way, I would love to be pointed in the right direction :)

Anyway, to get back to the topic: All my settings were right, but I had at one point scrollable background set to yes, and no matter how many times I have changed it, it kept coming back. So I deleted the background, and added it again. Now it works as it's supposed to =)

I would suggest you'd put all these example apps up on the link in the Interact Builder, where we can download sample apps, so others could use them too, without having to find these topics.

I think I know what was wrong, but we'll see.
I went to my profile, and added my e-mail. I signed up via Twitter.

Now I'll just have to wait and see, if I'll get any notifications. I'd love that! :D
Thank you once again.

Yes. And I was sent back to the Design tap. When I tried to enter Interact again, I got an error (that I couldn't copy).

It already says unsubscribe? Perhaps that's why I didn't click it.

Oh! Wow, great! Wishes granted by the minute, here ;)
Thank you.

Hahaha.. I love the sound on the second element :D

Btw, I got an error, after clicking the house element, and then trying to go back to interact mode. I could not copy it though. Perhaps conflict between versions of the builder?

How I wish we got an e-mail, when there are new replies to topics we created ourself  (and perhaps topics we commented on too). I hadn't seen this.

Thank you. I will check it out :)

You're the best! Thank you :D
