The next version of Nanogames (Version 3) will be available soon so during all of May 2011 we are running a virtual clearance sale of the current Version 2. Until the 21st of May the price of the download version of Nanogames (normally US$89.00) will be just US$17.50.

Is it really the full version? Are there any limitations?
It is the full version, however customers who bought the games at full price will receive a free upgrade to version 3 when it is released. Customers who buy on special can upgrade for the difference in price between the full price of version 3 and the price they paid for version 2 on special.
