What is a Sand Table?
The term "sand table" can be traced back to ancient war gaming sand tables, where military commanders would scale down mountains, rivers, and friendly/enemy positions to simulate the course of a battle on a tabletop. Its core purpose is to abstractly map things or concepts onto a manipulable or movable plane through a certain degree of abstraction, giving people a global perspective and room for operation.
In daily life, the forms of sand tables are far more common than we might imagine. Board games like chess, Go, and Kriegsspiel are essentially gamified representations of sand tables—the board is the plane, the pieces are the elements, the rules are the mapping, and each move is a simulation of the situation. In the fields of business and management, thinking models like the Business Model Canvas's 9-box model, SWOT analysis, and Gantt charts are also variants of sand tables—they abstract complex business elements or timelines onto a 2D plane for people to review, adjust, and make decisions.
What Kind of Thinking is TableMinds?
TableMinds is not simply "making a model," but a hypothesis-driven way of thinking.
It requires the user to first assume a theme or goal, and then, within a certain scope or model context, lay out different elements on a plane to observe their interactions and dynamic changes. This ultimately forms a complete, dynamic concept of how things operate, thereby guiding actual action.
In simple terms, TableMinds is like building a "miniature battlefield" in your mind, placing all relevant elements on it, simulating how they interact and evolve, and then making decisions based on the simulation results. It emphasizes not just "what you see," but "what if..."—this characteristic of "simulation" distinguishes TableMinds from simple categorization or listing, making it a dynamic and operable thinking tool.
What Scenarios is TableMinds Suitable For?
The application scenarios for TableMinds are extremely broad:
Games and Game Design: From board games to video games, TableMinds is the core method for rule design and balance adjustment.
Wicked Problem Decomposition: When facing complex and disordered problems, TableMinds helps break down big problems into manageable modules to be tackled one by one.
Model Design: Whether it's a Business Model Canvas or an organizational chart, they all rely on the abstraction and presentation of a sand table.
Dynamic Tactical Simulation: Tactical simulations in military, sports, and business competition, where TableMinds turns "armchair strategy" into a valuable rehearsal.
Troop Deployment: Resource allocation, team configuration, project scheduling—anything involving "putting limited resources in the right place" can benefit from TableMinds.
MECE Reasoning: Mutually Exclusive, Collectively Exhaustive logical decomposition is clear at a glance on a sand table.
What is the "TableMinds" Software?
The "TableMinds" software (BuffOC TableMinds™) is a thinking sand table tool originally designed by Ji Geng. It was first launched on Android and iOS platforms in 2016 and is one of the earliest products in the BuffOC suite of tools.
With the widespread application of AI technology, the TableMinds software continues to evolve. Its working principles and the underlying mathematical theories are detailed in the book "The Three Essential Tools for Super Individuals in the AI Age" by Ji Geng. Published by Guangdong Haiyan Electronic Audio-Video Publishing House on May 23, 2025, the book systematically introduces the development intentions, operating methods, and use cases of the three major tools, including TableMinds.
In 2025, the TableMinds mini-program was officially launched, while the Android and iOS apps were subsequently discontinued. Currently, "BuffOC TableMinds" is available as a WeChat mini-program.
As one of "The Three Essential Tools for Super Individuals in the AI Age" (the other two are "BuffOC Target To Truth TTT" and "BuffOC Mapping Mind Map MAP"), the brand positioning of the TableMinds software is an "essential tool for super individuals in the AI age." It aims to help users structurally deconstruct complex problems and quickly and flexibly present tactical sand tables, planning ideas, roadmaps, and thought projections.
Think with TableMinds, and TableMinds Can Carry It
The value of TableMinds lies not only in "thinking" but also in "carrying."
When you think with TableMinds, the TableMinds software can carry, but is not limited to:
Tactical Sand Tables: Competitor analysis, market layout, and offensive/defensive strategies in business competition.
Planning Ideas: All elements from product design to marketing campaigns are clear at a glance on the sand table.
Roadmaps and Thought Projections: Personal growth plans, team development paths, project milestones.
Complex Problem Decomposition Modules: Breaking down tangled problems into operable parts.
Decision Simulation: Simulating the different outcomes of different choices on the sand table to reduce the cost of trial and error in reality.
The three major tools correspond to three actions: "Unpack," "Achieve," and "Digest." TableMinds is responsible for "Unpack"—deconstructing complex problems into manageable modules. Target To Truth TTT is responsible for "Achieve"—transforming the deconstructed modules into actionable plans. Mapping Mind Map is responsible for "Digest"—systematically mapping information and knowledge. The three form a complete closed loop from deconstruction to execution to consolidation.
The essence of TableMinds is to make thinking operable, simulatable, and carryable—it's not about letting you daydream, but about letting you physically manipulate elements, test hypotheses, and optimize solutions on a "sand table." This "manipulable" characteristic is the core of what distinguishes TableMinds from other ways of thinking.
