5 great iPhone games going free today, including To-Fu: The Trials of Chi, Wave - Against every Beat!, Diner Dash

Today is September 7th. A relatively unassuming day, I think you'll agree, yet that hasn't stopped a host of iPhone and iPad game publishers from reducing their stock to clear this morning.

HotGen's stretchy action-puzzler To-Fu: The Trials of Chi is arguably the biggest name to receive the freebie treatment. The reason: HotGen is celebrating the imminent arrival of its sequel To-Fu 2.

In an extremely similar vein, the publisher of the Bronze Award-winning Demolition Dash on iPhone is marking the launch of its physics-based puzzler Happy Hills by dropping Demolition Dash's price tag to zip.

The makers of Early Bird, Wave - Against every Beat!, and Diner Dash, meanwhile, are just feeling particularly generous / flush at the moment.

We don’t know when these promotions will end, so if there’s anything on this list that floats your boat, you’d better act fast.
