Interactive Vector Boundaries • Fuzzy Recall • Spaced Repetition
Accuracy is calculated across your total guesses this round
First-try misses lower a unit's Global Score (0–100%) even if solved later in the round
CalGeo Master v2.0 — California Geography Trainer
📍 Pinpoint Mode: Given a city, county, CDP, or area code name, click its vector boundary on the map. Faster clicks earn higher speed bonuses!
✍️ Recall / Type Mode: A polygon is highlighted in amber with a pulsing beacon ring. Type the location's name. Smart Fuzzy Matching accepts answers that are 1–2 characters off (typos, transpositions, or missing letters) and common aliases (e.g., Ventura for San Buenaventura, Paso Robles, Carmel).
🏆 Memory Type Quiz: Start with a blank map of your chosen region and type as many California locations from memory as you can.
🗺️ Explore Mode: Freely pan, zoom, and hover over any boundary to study names, parent counties, and regional hubs.
Practice the entire state or drill down into specific regions: Rural Cities (163 Central Valley, Sierra Nevada, North Coast, and rural heartland municipalities), Bay Area, Los Angeles County, Central Valley, Southern California, Central Coast, Far North & Sierra, or any individual county.
Random Shuffle: Uses cryptographic randomness (crypto.getRandomValues) to generate a fresh, non-repeating random seed every game.
Anki SM-2 Schedule: Blends due review items with unseen locations and shuffles the session deck so you systematically master weak spots without repetitive question ordering.
