Glyphia — a world where Greek letters live. Every truth, every law, held together by flawless equations. Until an undefined operation appeared. And reality began to fracture. You are the Operator. Together with π — "Pion", a lifeform born inside the system, you must rewrite the broken equations. But the calculations grow unstable. Impossible results emerge from the void. And then you realize the truth: This world is running on something older. A system that was never meant to be found. 💡 Pion's Theorem reinvents arithmetic as a strategic card game. Every number, every operator, every bracket is a card — and every card is part of your deck. Combine number cards, operators (+, −, ×, ÷, ^...), and special cards to construct an expression that hits the target value. Simple on the surface — but once card weights, use counts, and sticky effects come into play, every round turns into a fresh logical puzzle. 🎮 Four Distinct Modes 🧩 Puzzle — The classic challenge: use the given cards to reach the target number. 45 handcrafted stages that also serve as a gentle tutorial introducing every core system in the game. 📅 Daily Challenge — A new puzzle every day.
