see-ta-del ... See-Ta-Dell ... SEEEEE-TA-DELLLL! Yes, coming in at #7 it's the arcade puzzler that practically defined the genre: Citadel from Superior Software, developed by Michael Jakobsen! Citadel is a fully immersive game that combines wonderful mechanics, graphics and sound effects, spread across over 100 rooms filled with challenges and perils. Coded to perfection, there have been many pretenders to the throne but only Citadel can take the arcade puzzler crown. Enjoy!
