Recommended ways to promote a "not-so-hot" app for FREE

[windrider07]

How would you promote a not-so-hot app with no budget?

What's so cool about the app? It's free....ok, that's cliche...there's a lot of apps that are free. It is also one of the very FEW apps that is BOTH free and has MORE games within one app than any of the top 10 apps in its category. Solitaire* is in the top 50 in US, EU, Japan, and China. It is free with 36 games, more games than most of the apps in the top 20 in the app store. Problem is, the big app review sites won't review the app because it's not unique, original, or hot. It's just a Solitaire game. My goal at the moment is to aim for the small blog/review sites and social networking sites. What do you guys suggest?
