i think it would be fun if there was a section with a few small games cause they help your brain to focus and it makes it more fun
Wall of text, so I didn't really read the previous comments.
However, the standard ideas of word search/crossword/hangman would be a welcome addition in my eyes.
Edit: I'd just like to add something further. I've installed games like "Hangman" on my iPhone, but all the decent ones I have used have used continental Spanish, which is a bit of a pain. Furthermore, the problem with additional game style learning tools for iPhone I've encountered, is that the vocabulary clearly isn't the same. This makes it useless to use other apps to practice Duolingo words, and the words I have learned through them I generally end up forgetting because Duolingo doesn't include them.
If you're getting frustrated with something or can't get something, such as a word in the language you're learning, skip the word by translating it when needed. It may sound harmful, but doing so you'll learn the word and it'll get drilled into you sooner or later by the translating, or at the very least you'll learn the context from knowing the other words around it. For example in German, "Das Mädchen spielt, die Frau trinkt." is The girl is playing/plays, the woman drinks/is drinking. If you got stuck on what wording the trinkt would be from the context (Doubtful seeing how basic this example is), you could look it up instead of failing till you get it, and in the process quiting in the process or getting stressed or upset in some way. Eventually you'll get that trinkt is drink/is drinking in general, at least in this context. As you advance you'd see that there is trinke and Trinkst, trinkt, trinken and all these other closely looking words, and you might mix them up at first, it's better to "skip" them than to get pissed and slow yourself behind because of one word, or cause yourself to get discouraged from learning the language, so skip them.
Alternatively, if you're losing interest in the language or are getting frustrated with it, take up a second language outside of the family, for example German and Portuguese or German and Spanish, or Spanish and Dutch, but never learn German and Dutch or Portuguese and Spanish because they're in the same family, therefore easier to mix up when learning together.
Furthermore, if you just aren't having fun in general learning the language or can't stand it for other reasons than above, try putting some music very low in the background while working on Duolingo or try other little things to make it less painful. It might not be a good idea for focusing, but you could just be getting distracted because it is too silent doing duolingo, while your space around you is busy and noisy, or you simply just hate the silent-ness and wander off into the yonder while it's so calm.
Don't force the language on yourself though, Simon. If it's just Spanish not being interesting, try Portuguese or something like it. They're slightly different, but they're both very useful for South America and (some) other areas of the world. Just remember learning the language won't be fun for a fair amount of time, the first few lessons, sure, then it'll get harder(for most languages that is), but soon after that little hump it'll get much much easier and you'll be able to read and actually use the language decently, therefore becoming much better at it much faster, not to mention in funner and funner and easier and easier ways. From the looks of your Duo-lingo profile, you're getting there so that you could possibly read some things and notice more and more things in the language simply by listening to songs and other audio-things. Once you get a little more, you could start playing games, reading books, watching news and tv not to mention movies, and even talk on forums or online games in the language at least a little. All should be good practice, and it shouldn't be boring at all, it'd just be doing your regular "fun" activities using electronics that is, in Spanish in your case seeing as that's the language you seem to be trying to learn. And by all means, there's plenty of Flash game websites, Java websites, Forums, and console-port games or console games that have Spanish settings, servers, or have a Spanish community.
Sorry for such a long post, I just wanted to cover the majority of the places (s)he could be coming from.
EDIT - I personally don't care to have games added, but that's mostly just because I want languages such as Russian, Arabic, Chinese, or even Swedish or other not so well-covered languages added to Duo-lingo as soon as possible.
Am I missing something? Your intention might have been to cover as much ground as possible, but I think that you are straying too far from the subject. First of all, what makes you think that Queri is frustrated with something? I think that it is more a request for more diversity in the learning experience by adding games to test language knowledge. This isn't the first topic to request that and kristinemc encourages people to share those kinds of ideas in discussions, as has been done here: http://duolingo.com/#/comment/309051
You might also notice that people in that discussion are talking about a different kind of games than the kind that you are describing. Based on your comment I would guess that you play video games regularly and that you thought that Queri's interest in games is similar. I think that there is merit in playing text based story games as they might be easier to decipher with a dictionary and from context then a movie, but people seem to be more interested in puzzle games that test their knowledge. Duolingo already shows influences of "gamification" in the way that it keeps track of scores, but I agree that there is room to make the experience more entertaining.
I'm not sure if any of your language tips are of relevance here as there isn't any talk about frustration or comprehension difficulties in the original post. The suggestion to start learning a new language isn't only far from the initial question; it might actually cause more distraction from the first language someone is learning. There have already been several discussions about whether it is possible to learn multiple languages at the same time. I agree with you that it might be easier to learn languages from different families together, but that doesn't mean that you should just do it. Studying more languages at the same time might make things interesting for a while, but what will you do if you get bored again? If you continue trying new languages, then you will learn a little of everything, but you could easily end up mastering none. I've made that mistake in the past and I'm glad I had a look at what more experienced language learners had to say on the topic. I'm now focussing on completing one tree at a time as that makes it more clear what I'm focussing on. If I do that long enough, then I would still end up learning all the languages I started. Here are some websites that I looked at:
I hope that you are not too disappointed by my reaction. There is some very valuable information in there about how you can pick up words from context and how to build up towards more difficult material, but I'm not sure if that is what the initial post is about.
I was thinking some of it might be a little off-topic, but I have been seeing tons of people learning languages in the way duolingo teaches you at the start shy away for many reasons, some being it too hard (skip words), some of out of frustration from the words or some from general boring of the language. If (s)he's wanting games on the site, in this context at least, it suggests he (could) or has already experienced some issue, be it frustration or something causing him to get distracted, or maybe (s)he just doesn't like the language. If there's books, games, or something (s)he could use, or will be able to soon to learn, then that would be what they're looking for. It may not be on this site, but you should never keep all your eggs in one bundle anyways, and I'm sure y'all would recommend listening to some music or something in the language you're learning once you get up there in it, if not right away.
I noticed (s)he was learning Spanish, here in Texas it's considered good to learn. If they simply are learning Spanish because others told them to, and not for business or something right away that is important for the job you have or the partner your with, that could be the issue they're having. They might not like how it sounds, or don't find it interesting/entertaining or simply see nothing in the language. Which I doubt would happen with Spanish, because of how big of a language it is, but it still could happen if they aren't searching for what they like, but just grinding on practicing the language instead of immersing their self in the language/possible-culture.
Now the learning two languages thing was really off, but that was just because if they had the time to take another up to avoid getting stopped in the first one, and to keep things fresh, then they could do it if they tried seeing as two languages at once isn't too difficult with the time and tools, although you'll need a lot of time. I've been thinking about taking up another language on here because German does get a little boring sometimes, but I simply don't have the time because in a day I'll be heading back to school for a few weeks till summer comes and hits Texas. On top of that I've recently started boxing, so as you can see, no time. More-so, I never said they should bounce around between languages, however I don't say it's bad, I wouldn't recommend it for most people. But to have a break from one language, to go to the other one you're learning, that's not bad at all as long as you have the time to do them both and you don't mix them up, which is doubtful in a situation with a Germanic language with a Latin language, just as it would be with a Slavic or Asian-oriental language with a Germanic or Latin language.
But I did go a little off-topic, I guess I shouldn't have assumed so many things, I think I've just been seeing too many people get bored or frustrated at languages recently and quit them.
You can use Kahoot, a great educational tool for both adults and children, user created quizzes in many languages, including language schools. Its computer/Ipad based that is interactive so that participants can take part using their mobile phones. But, nevertheless, duolingo has the perfect forum/infrastructure to set something more interactive to offer to student groups.
