I&#x27;d emphatically recommend Zen Bound and Zen Bound 2.<p>More than most other mobile games with good touch controls, the Zen Bound games really took advantage of the tactile nature of current mobile devices and their touch interfaces.<p>Aside from the mechanics, they were also pretty relaxing, while some of the levels managed to be simultaneously challenging while remaining completely passive. A very gentle and non-frustrating form of challenging that not many games manage to achieve.<p>I don&#x27;t think Zen Bound gets enough praise as a game that is unique both from a gameplay perspective and how well it relies on the interface of the underlying device.
