AppSpy is, of course, the best resource on the planet for iPhone game reviews, yet with only one full-time reviewer on board to cover the scene, the odd beaut is bound to slip through our trawl net.

That's why each month we publish a round-up of the Top 10 iPhone games sourced from the Quality Index.

In May, Launching Pad Games's casual arcader Mighty Fin leapt like a salmon to fin-ish 3rd on the Qi countdown, only beaten out by Chaos Rings Omega and First Touch Soccer.

We ourselves awarded it a 4/5, praising its single-finger simplicity, clever level design, and infuriatingly catchy soundtrack.

The solitary piece of criticism levelled at Mighty Fin was its - cough - shallowness, which may well have been addressed with the recent introduction of a Survival mode.

Launching Pad Games also promises more levels and Game Center achievements throughout the summer, so keep an eye on Mighty Fin over the near future.
