Spider and Web is all about trial and error. Yet it somehow manages to make those trials and errors fun, intriguing, and occasionally illuminating. A too heavy-handed description of the story, or even the gameplay, would ruin the several "a-ha!" moments that Plotkin has set up for you. Play for a few minutes and you'll see the first. The second is nested much deeper.... While the game provides enough hints to keep things moving along, I was occasionally overwhelmed by the multitude of items in my possession, and the occasionally maze-like layout of the setting. However, there's a cognitively dissonant moment near the end - you'll know it when you see it - that could only be pulled off in IF, and only by somebody like Plotkin. It's when - no, I'll never tell.
