Harnessing Creativity in Horror and Gaming

The Blocktoberfest Game Jam 2025 has officially commenced, inviting a global assembly of game makers, artists, and horror enthusiasts to engage in a creative challenge that blends iconic game titles with innovative design on the Portals platform. The event, hosted online, draws support from classic game giant Atari and the horror-specialty platform Block of Horror, aiming to merge the essence of established horror and sci-fi titles with modern 3D browser technology.

Options for Creators

This year, participants can select from one of three distinctive tracks—Atari, Block of Horror, or the Artist Track. The Atari and Block of Horror tracks allow creators to dive into a rich repository of established titles, crafting playable scenes that maintain the nostalgic essence of games like “Haunted House,” “Dracula: The Undead,” and newer indie horrors like “CARRION” and “HELL FROZEN OVER.” Meanwhile, the Artist Track caters to 3D artists focusing on visual storytelling and atmospheric design without the need for intricate game mechanics.

Guidelines and Project Parameters

All entries must be crafted using the Portals platform, renowned for its no-code, browser-based building environment that simplifies game and scene creation. Participants must ensure their projects not only adhere to the thematic requirements but also the technical specifications set by the event rules—providing a seamless in-browser experience and adhering to a strict code of conduct that excludes NSFW and abusive content.

The Competition and Prizes

Spanning across the globe, the competition boasts a substantial prize pool of $50,000 USD, divided among Big Prizes for the main track winners and Mini Prizes awarded for creativity and community favorites. The judging phase, scheduled from October 25 to October 30, will rigorously assess entries based on their adherence to the chosen game IP, gameplay quality, atmospheric achievement, browser performance, and original innovation.

The Conclusion and Public Showcase

As the game jam wraps up, all qualifying submissions will be displayed during a virtual showcase aligning with Halloween week, from October 31 to November 3. This event will not only spotlight the winners but also offer a platform for public interaction, where enthusiasts can explore the creative works and cast votes for community awards.
