Players write code using a simplified, fictional assembly language with instructions like MOV, ADD, SUB, and conditional jumps to control data flow between processor nodes.
The TIS-100 computer consists of a grid of independent processing nodes that must communicate explicitly to solve problems, forcing players to design parallel and distributed algorithms.
A curated sequence of puzzles gradually introduces new instructions and architectural constraints, each requiring a specific computational solution to progress.
After solving a puzzle, the game scores solutions based on the number of execution cycles, instructions used, and nodes utilized, encouraging iterative refinement.
Includes a mode for players to create, share, and solve custom puzzles, greatly extending the game's lifespan and variety of challenges.
Educators and students use TIS-100 as a supplementary tool to teach and learn core computer science concepts. It provides a concrete, interactive way to understand assembly language, CPU architecture, parallel processing, and data flow. By solving puzzles, students internalize how instructions manipulate data and how components of a computer system interact, bridging the gap between theoretical knowledge and practical implementation.
Experienced software developers use TIS-100 to challenge their problem-solving skills and think differently about code. The constrained environment forces efficient, clever solutions and provides mental exercise in low-level logic and optimization. It serves as a 'brain teaser' that helps maintain sharp algorithmic thinking and can offer a fresh perspective on concurrency problems encountered in high-level development.
Players who enjoy logic puzzles, escape rooms, or challenging games are drawn to TIS-100 for its unique premise and satisfying progression. It offers a deep, cerebral gameplay experience where the 'win state' is a functioning program. This use case highlights the tool's success in making programming intrinsically fun and rewarding for a non-professional audience.
Professionals working with or maintaining legacy embedded systems or low-level code can use TIS-100 to intuitively grasp the mindset required for such work. The game's fictional 1970s aesthetic and resource-limited architecture mimic the constraints of older hardware, providing a safe sandbox to explore concepts like memory limitations, direct hardware control, and the absence of modern abstractions.
Members of the TIS-100 community engage by creating custom puzzles in the Sandbox mode and competing on leaderboards for the most optimized solutions. This use case revolves around creativity, sharing knowledge, and friendly competition. It extends the tool's value from a single-player experience to a social platform for showcasing programming prowess and clever puzzle design.

3D Slash is a unique, block-based 3D modeling software designed to make 3D design intuitive and accessible for everyone, from children and educators to hobbyists and professionals. Inspired by the visual simplicity of retro video games, it uses a 'destruction' and 'construction' metaphor where users carve models out of a virtual block of material using tools like a hammer, chisel, and trowel, rather than manipulating complex vertices and polygons. This gamified approach significantly lowers the learning curve associated with traditional CAD software. It is widely used in educational settings to teach STEM concepts, design thinking, and spatial reasoning. Users can create models for 3D printing, game assets, architectural visualizations, and simple prototypes directly in a web browser or via desktop applications. The platform emphasizes creativity, speed, and fun, positioning itself as a bridge between playful digital making and practical 3D output.
Achieve3000 is an adaptive literacy platform designed primarily for K-12 education, focusing on improving reading comprehension and critical thinking skills. It uses proprietary AI and natural language processing to dynamically adjust the reading level of nonfiction articles to match each student's individual Lexile measure, a standard for assessing reading ability. The platform provides differentiated instruction by delivering the same core content at multiple reading levels, allowing all students in a classroom to engage with grade-appropriate topics while reading at their own level. It is widely used in schools and districts across the United States to support English Language Arts instruction, intervention programs, and college and career readiness. The system includes embedded assessments, writing prompts, and data dashboards for teachers to monitor student progress. By providing personalized, leveled content, it aims to accelerate literacy growth, particularly for struggling readers and English language learners.
Acuant is an AI-powered legal research and document analysis platform designed to assist legal professionals, such as lawyers, paralegals, and corporate counsel, in navigating complex legal information. It leverages advanced natural language processing and machine learning to parse vast databases of case law, statutes, regulations, and legal precedents. The tool helps users quickly find relevant legal authorities, analyze documents for key clauses and risks, and prepare for litigation or transactions. By automating time-consuming research tasks, Acuant aims to improve accuracy, reduce manual effort, and enable legal teams to focus on higher-value strategic work. It is positioned as a modern solution for law firms and in-house legal departments seeking to enhance productivity and decision-making through AI.
