Knock-Knock Game in IOS

A horror game about insomnia

Walkthrough, Guilds, Tips on this special game

Our Site Score

85/100

Knock-Knock is one of those rare atmospheric horror titles that doesn't rely on jump scares, but rather a deep, gnawing sense of unease. You play as a world-weary Lodger in a cabin that feels alive, or at least haunted by your own unraveling sanity. The gameplay loop of fixing lights and hiding from 'Guests' is simple but incredibly effective at building tension. It’s a game about the fear of the unknown and the frustration of insomnia.

The art style is gorgeous in a macabre sort of way, reminiscent of a twisted storybook. While the logic can sometimes feel obtuse—leading to moments where you aren't quite sure why you failed—that confusion actually feeds into the narrative theme of losing touch with reality. It's a slow burn, but for players who value atmosphere and psychological depth over traditional action, it’s a hauntingly beautiful experience that lingers long after the sun comes up.

Dinsun Review

Ice-Pick Lodge always makes weird stuff, and Knock-Knock is no exception. It’s got a great atmosphere—genuinely creepy and surreal—but the actual 'playing' of it is a headache. You spend your time slowly walking from room to room, clicking on lights, and waiting. The rules are never explained, which is 'artsy,' I suppose, but for a gamer, it’s just annoying. It’s one of those games where you’ll lose and have no idea why. I appreciate the vision and the lack of cheap jump scares, but the core gameplay loop is just too tedious to fully recommend. It’s a mood piece, not a masterpiece.
