Pion's Theorem Demo

Solve equations. Build decks. Break the system. A math-fueled deckbuilding puzzler where you combine number and operator cards to hit the target. Master four modes — Puzzle, Daily Challenge, Competitive, and Strategy — with π at your side. Casual to pick up. Dangerously deep to master.

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 — &quot;Pion&quot;, 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. Solve it to earn Kahlua.🏆 Competitive — Hit multiple objectives at once (≥, digit counts, totals…) with a fresh card set each week, and climb the global leaderboard.♟ Strategy — The deepest mode. Between rounds, use card management actions to dynamically reshape your deck. You carry over whatever cards you have left — so survival itself becomes the challenge.✨ Key Features🃏 True Deckbuilding — Fuse Cards, Increase Weight, Increase Uses, Unban Card, Remove Sticky, Sell Cards — full-featured deck construction🎴 55 Cards in Total — From essential number cards to a colorful lineup of special cards with unique effects💎 Card Attributes — Sticky cards can't be removed from your play deck, Banned cards are locked out this round, Weight affects objectives and scoring, and Use Count limits how often a card can fire.
