You may find it helpful to try our limited edition of BrainWare Safari for yourself. The limited interactive demo will allow you to try two levels of each of five exercises. The levels may not be consecutive to give you an idea of how an easy level and a more difficult level work. Two versions are available for download -- one for PC users and one from MAC users. (The MAC version will not run on the new Lion OS).
Just fill out this registration form and follow the onscreen instructions to try out the BrainWare Safari Interactive Demo.
