About Vectron

Five Worlds, One Engine

The Vectron engine powers a multi-world curriculum. Five Worlds are live today: Algebra, Calculus (derivatives, limits, and integration), Trigonometry, Probability & Combinatorics, and Geometry.

• 30 Rounds per Unit: Difficulty escalates progressively, ending in a mastery stage.
• Study Guides: Slides with explanations, formulas, and examples before every unit.
• Adaptive Difficulty: Questions evolve based on your performance.

Stars & Progression

Earn 1-3 stars per lesson. Stars unlock new worlds and contribute to your XP through 16 ranks – from Beginner to Vectron Hero.

How Energy Works

Energy is spent only by Lessons, keeping the pace balanced. Solo Training and Challenges are always free.

• Free Users: 5 max energy.
• VIP Members: 10 max energy (double capacity).
• Regeneration: 1 energy every 60 minutes.
• Refills: Use Taaffeites or watch ads to refill instantly.

Earning & Spending

Taaffeites are Vectron's in-app currency. They reward your dedication and skill.

Study Card System

Spending a Study Card is what sends a match request and opens a Study Buddy pairing. New accounts start with 1 free Silver Card.

• Silver Cards: Hold up to 28. Claim 1 free every 24 hours, or buy more for 3 Taaffeites each.
• Golden Cards: Hold up to 4. Buy for 5 Taaffeites each, or earn as a reward.

Study Buddies, Groups & Chats

Match with compatible partners, message privately in Study Chats, challenge each other, or join Study Groups (max 30 members) to collaborate. No public chat. Everyone stays safe.

Copy an equation from the Math Keyboard, or a formula from Math Formulas, then paste it into a Study Chat or Group Chat: it renders as real typeset math, not raw LaTeX.

Competitive Gaming

Real-time PvP matches with friend invites and a live lobby, powered by the cloud for lag-free gameplay.

• Multiplayer: Math Duel, Crossmath Race, KenKen Race, and Prime Strategy Duel.
• Solo Training: Free, unlimited practice for every game mode.
• Daily Challenge: A fresh challenge every day.
• Challenge Arena: Timed mini-games, free of energy cost: Multiple Choice Quiz, Number Memory, Speed Comparison, Balance Scales, Prime Checker. Beat the target score before you run out of questions or wrong answers.

Entry costs Arena Points and scales with your level: 20 below Level 5, 40 at 5-8, 80 at 9-11, and 120 at 12+. Win and you double your stake back; lose or draw and you forfeit it. Out of points? 2 Taaffeites buys you 40 more.

Always Play Against Vectron

Vectron layers 21 distinct personalities on top of its chess analysis, so you're always playing "vs Vectron," not a bare stock engine with no character.

• Analysis Board: Set up or analyze any position, including complex endgames, and ask for the engine's best move anytime.
• Chess Solo: Timed matches against a chosen personality, plus "Find the Mate" puzzles.
• Vectron vs Vectron: Spectate two personalities, each with its own playing style, facing off.

21 Personalities

From Attacking to Defensive to Purist. Vectron never plays a genuinely bad move; a personality only expresses itself among the moves it already rates roughly equally good.
