Murder mystery logic, math cryptogram, word search

      The puzzles on this site were all generated by software programs designed by Leithauser Research, a software development company. We create shareware software, mostly business software (like Date Calculator, which will calculate days between two dates or calculate date in the future or past ) and Computer kiosk software and Internet cafe software, as well as Internet access control (like Internet Password Lock, which will block Internet access and Web Site Zapper, which allows you to block Web sites). 

Are you concerned about the safety of your child or children on the Internet? Are you concerned that they might be viewing sites they should not be, or just that they are spending too much time surfing the Web? Do you want to restrict or limit how much time your children can play games or surf the Web on their computer? You can use the Internet Password Lock software.

Do you want to make some money by renting time on your computer? We have Computer kiosk software or Internet cafe software. This software lets you sell passwords that give access to the computer and its programs for set periods of time, or track how long a person is on the computer or using certain programs so you can bill them later.
