🎮 Multiplay

A smart, playful multiplication trainer designed to help kids move from counting to instant recall. Multiplay uses spaced repetition and adaptive learning to make practicing math feel more like a game and less like a chore.

🧠 How it Helps Kids Learn

Unlike simple quiz apps, Multiplay uses cognitive science principles to guide learners through the multiplication tables.

⚡ Tiered Fluency (Speed Matters)

Getting it right is just the first step. True mastery means instant recall.

• Learning: Identifying the fact.
• Speed Building: Getting faster at calculating.
• Fluent Mastery: Answering in under 3 seconds. The app tracks these speeds to ensure kids aren't just counting on their fingers.

📈 Adaptive Table Progression

We don't just go from 1 to 12. Multiplay introduces tables based on their pedagogical difficulty:

1. The Patterns: 1, 2, 3, 5, and 10 (The easiest to grasp).
2. The Extensions: 4 and 11.
3. The Logical: 9 (finger tricks) and 6 (extension of 3).
4. The Challenge: 7, 8, and 12.

Smart Auto-Unlock: When a child masters about 65% of their current tables, the system automatically introduces a new one, keeping the challenge just right.

🎯 Controlled Focus

To prevent frustration, the app manages exactly what the user sees:

• Active Set: We focus on just 15 facts at a time. Once one is "Mastered," a new one is rotated in.
• Weighted Practice: The app spends 60% of the time on the 5 facts the user finds hardest, ensuring they actually improve where it matters.

✨ Features

• Modern Design: Clean glassmorphism UI with vibrant colors.
• Tactile Feedback: Subtle haptic taps for correct answers and error signals.
• Detailed Stats: A visual heatmap showing exactly which facts are mastered and which need work.
• Offline First: Works anywhere, with progress saved locally in the browser.

🛠 Tech Stack

• Svelte 5: Responsive and reactive frontend.
• Web Workers: The learning engine runs in the background to keep things smooth.
• IndexedDB: Persistent local storage for user profiles and progress.
