Looking for some input for a leader board / incentive system for a new iOS puzzle game app. What are your suggestions?

I would suggest you self-publish. Let me break down the mobile game landscape for you in a single statement: *You can only grow a game if your LTV (Lifetime Value) is greater then your CPI (Cost Per Install).* I assure you, that once you have that formula successful, finding money to support continued growth of your game at extremely favorable terms to yourself is not going to be a problem. If you don't have success with the above formula, then it doesn't matter if you have a publisher, your game's not going to be able to grow and make money with them either. There are only 2 conditions which you should consider a game publisher: 1) You need money to complete the game. (ie, no way will the game exist unless you get the money.) 2) For specific geo locations, such as China where there are people who can properly localize and market the game. That's it. I believe there is no grey area here and I've had experience on both sides of the table, including being the first 3rd party publisher signed by Zynga. The latest game I built is currently in the top 100 grossing chart (Cookie Jam) and it's there because we have successfully cracked the formula above. Its quite simple, but really difficult to achieve. Good luck! -Michael.

Online, however, there could be anything going on behind all of that technical wizardry, right? Technically that is true, but online bingo played at regulated websites is as fair, safe, and trustworthy as the real thing.

I guess the best answer is, it depends. What kind of mobile game are you marketing? Who are you targeting? For what platform? (iOS, Android?) Different ad networks work better than others depending on the type of game. A good place to start would be MoPub, MDotM, Manage, and Insight.

There are three types of metrics that you want to collect. 1) Aggregate metrics 2) Cohort metrics 3) Funnel metrics A tool like Flurry is OK for aggregate metrics. Google Analytics for mobile is probably the better choice depending on your needs. For cohort and funnel metrics, I prefer using Mixpanel. And for tracking App installs I prefer Tapstream. For a deeper dive into the above analytics types above, I recommend reading Lean Analytics by Alistair Croll and Ben Yoskovitz.

I'd start with messaging the admins of the various Facebook groups dedicated to mobile game development and asking if they'd be willing to 1) enable you to put up a post about the SDK, and 2) pin the post for a week so that you get a bit more visibility within those communities. You can also find the appropriate thread on the various mobile gaming forums and chime in there. I would recommend trying to be helpful 9 times before you ask for something once. You'll notice a much better response if you've become an active contributor to each community before you start selling your stuff, no matter how soft the sell and no matter how valuable the stuff. Hope this helps, Austin
