Founded in 2004, Big Brainz is a game development company focused on teaching children mathematics through fun and engaging games. Known for their passion project, Timez Attack the game proved to many that it is possible to craft an educational experience through video games rather than cramming lessons into children with minimal effort.

Timez Attack launched initially with a Multiplication edition, followed by Division in 2011, and Addition and Subtraction the following year.

In 2016, Big Brainz was acquired by Imagine Learning, a business deal that provided additional funding and extended reach beyond Big Brainz's initial scale.

In the same year, the full version of Timez Attack was made unavailable for purchase in March 2016. Despite this, Imagine Learning allowed consumers who purchased the game to re-download it alongside maintaining the ability for anyone to download the free version of Timez Attack.

Unfortunately, in March 2018, the Big Brainz website was taken offline, which now re-directs to Imagine Math Facts. Timez Attack's download pages were also affected, which prevented those from downloading either version of Timez Attack from Imagine Learning.

Today, while Timez Attack cannot be digitally purchased or downloaded from Imagine Learning, the full and free versions of TImez Attack can be downloaded and played via internet archive downloads.
