The Humble Bundle is one of the best deals in gaming, but the Humble folks also do smaller weekly sales. The newest weekly sale bundle includes five total games, three of which come with Android versions.
The sale is brought to you by Cipher Prime, which is the developer of all five titles. The three Android titles are fairly popular, but aren't the kind of thing everyone knows about. Fractal and Splice are both abstract puzzle games with very polished visuals.
