Developer Secret Exit has dropped the price of its Zen Bound games in celebration of everybody's favourite hay fever-inducing season, summer.

The goal of each game is simple - you have to paint a number of different-shaped objects by wrapping a length of rope around them, using touch controls.

To succeed, you have to cover a set percentage of the object with only a limited amount of cordage.

The original Zen Bound outing features 76 levels of puzzles, and a 22-minute downtempo soundtrack to indulge in as you play.

Zen Bound 2, however, is a universal app with over 100 levels, new gameplay modes, paint bombs, and a 45-minute soundtrack.

It also features Retina display graphics and gyroscope support, and Game Center for achievements.

Both games are highly popular here at Pocket Gamer Towers earning Platinum and Gold Awards respectively.

You can grab them from the App Store for 59p/99c.
