關於此遊戲

Every argument begins with set of premises that, if true, necessitate some conclusion. Your task is to prove that the conclusion does indeed follow.

Given a set of premises, apply rules of inference and replacement to derive new propositions — step by step — until you reach the conclusion. Each level is a proof waiting to be completed.

As a newly aware intelligence, each proof explores themes of being and essence, virtue, the soul, causality, and the pursuit of truth. Simply put, you are a mind reasoning its way from first principles toward understanding.

Features

• 120+ handcrafted levels spanning propositional logic and predicate calculus, levels varying both thematically and mechanically

• 23 rules of logic — 7 rules of inference (Modus Ponens, Modus Tollens, Hypothetical Syllogism, and more), 11 rules of replacement (Double Negation, De Morgan's Laws, Transposition, and more), and 5 quantifier rules (Universal/Existential Instantiation and Generalization, Quantifier Negation)

• Gentle learning curve — 18 tutorial levels introduce one rule at a time, building from simple one-step proofs to multi-step chains

• Deep complexity — later levels feature nested quantifiers, multi-variable domains, and proofs requiring 10+ derivation steps

• Intuitive drag-and-drop interface — slot propositions into rules, see the result, and build your proof step by step

• Par system — every level has an optimal solution length; can you find the shortest proof?

• No time pressure — think as long as you need; every proof waits for you

• 60+ Steam achievements — milestones, rule mastery challenges, and hidden achievements for completionists

• Cloud saves — pick up where you left off on any machine

I used standard agentic tools for things like translation and making simple icons. Some images/effects were created with Stable Diffusion XL Base 1.0 (sd_xl_base_1.0.safetensors). The background music I iterated on with a local ACE-Step setup.
