Here in the Armor office, we had a long discussion on what makes addicting games, well, addicting? We've made a page on the subject, and picked our own addicting games - but we felt we really should get community opinion on the matter. So we've spawned forum threads here in Flash Games to get your feedback! The most community voted games will get a place of honor on our "Addicting Games" page.
This thread focuses on puzzle games.
Tell us which one you feel is most addicting, and why?
I might be nearly alone here (especially so given the game's ratings) but I found Jahooma's Logicbox to be one of the better puzzle games on the site. Its use of real-world programming logic to create open-ended puzzles is ingenious, and the difficulty is a step up from most other games on the site while still relying solely on the player's logic abilities to progress.
So it might not make it to the Addicting Games section, but I felt it was worth an honorable mention at least. =D
