Edutaining Kids - "Remember the mini cliffhangers at the end of each and every chapter of Nancy Drew books? They ensured young readers would keep turning the pages. This [Treasure in the Royal Tower] software title has a similar effect, except with this fourth mystery adventure in the Nancy Drew CD-ROM series, you won't want to stop clicking."

Discovery School - "This is yet another successful mystery adventure on CD-ROM from the excellent Nancy Drew series. The program combines a gripping story line, brain-bending puzzles, and a fantastic atmosphere for fun detective work. The result is a challenging but very satisfying experience for children ages 11 and up."
