US day off Labor Day originated in 1882, when the president issued a national holiday following a number of worker deaths at the hands of the US military during a strike. To celebrate, we get to play a Transformers game on our iPhones!

From today and following through to September 7th, a massive number of Glu games are on sale for wonderfully reasonable prices on all manner of handheld systems. If you’ve got an iPhone, iPad, Android, BlackBerry, or even a Palm handset, there are price cuts for you.

Choice cuts include addictive time-sink Jump O’Clock on iPhone, rock god sim Guitar Hero 5 on Android, and smart strategy game Transformers G1 on iPhone and Palm.

The massively complete list is right here. Remember, prices shoot back up on the 7th.
