The application runs as applet using java 7.
Applets are listed in the windows system program page and the properties in the safety panel must be adjusted to enable applets to run.
Please choose the safety level "medium".
Next a safety warning must be accepted to trust me and my application.
The application is tested for firefox only and perhaps in other browsers there are other ways to accept applets.
The application is free for use, but not free from mistakes in programming, nevertheless if you read carefully where to click and where NOT to click, you can enjoy the game.
You do not play against the PC, but with his help searching solutions is much better and faster.
All program hints are in English. Any feedback is helpful.
