Below are four free applications for the Touchpad.
Differences : 70%
A reasonable spot the difference game, but a bit to picky on selections and some images have differences (due to the photo editing, which are not counted as different.)
Basketmania : 68%
Not a true Touchpad game, it is upsized, but still plays well, and good fun. Several mode unavailable until you get the premium version.
Bubble Birds 2.0 : 61%
This is a free version of Bubble Birds 2.0 Premium, it is not a great advert with crashing, failing sound. The gameplay itself is similar to Puzzle Bobble, but does feel like a cheap clone.
EvaDots Evolved : 56%
Nice and simple action puzzle game, but suffers from slow down when you start doing well, making it unplayable.
