Could you read the New Testament in its original Greek? KoineQuest doesn't just teach you the words — it shows you exactly how close you are — word by word, book by book. HOW IT WORKS Play quick, retro pixel-art rounds through the New Testament, chapter by chapter. Every word you master raises one number that matters: how much of the actual Greek text you can now read. MY PROGRESS — Watch your reading coverage grow across all 27 books, from Matthew to Revelation. "You can read 43% of John" hits different than a test score. MY WORDS & REVIEW — Every word you've studied is collected and ready to review in smart order: the ones you're still learning first, then the ones quietly slipping away. Tap any word for its full card — all its forms, its meaning, and how often it appears in the New Testament. PRACTICE YOUR MISTAKES — Missed words become their own practice list. Loop them until they stick. No lives, no pressure. DAILY STREAKS — Three minutes a day keeps your Greek alive. An optional reminder has your back before a streak breaks. MONTHLY QUEST — Pick a pixel avatar and climb a fresh leaderboard every month with learners around the world. TWO DIRECTIONS, THREE DIFFICULTIES — Recognize Greek → English, or prove real recall with English → Greek. From first-semester student to seminary review. Fully available in English and Portuguese. Start free with the complete First Epistle of John — real biblical text, not a demo. Unlock more books as your quest grows. Whether you're starting seminary, taking your first Greek class, or simply want to meet the Word in its own language: the text that shaped millennia is closer than you think. Sola gratia.

Test your skills and have fun with Rlinguo, a playful game where you guess which package a function belongs to! While it may not make you a better developer, it’s certainly an entertaining challenge. Can you tell that mean() belongs to {base} and median() belongs to {stats}? (We know—it’s a little annoying that they’re in different packages!) Rlinguo is more than just a game; it’s a proof of concept demonstrating the power of R in mobile development. Here’s what makes Rlinguo special: - R on Mobile: Yes, you can run R on your phone! Rlinguo uses R behind the scenes to power the game, from sampling functions to running built-in functions like runif() on the About page. - Data Science on the Go: Rlinguo brings a genuine data-science experience to your mobile device. The app stores data in a local SQL database, performs queries with R, and sends the results back to JavaScript for visual feedback—just like any data science project. - R Packages Integrated: Each time you guess correctly, you’ll get a praise::praise() (we couldn’t resist). All powered by R packages within the app! - Smooth User Experience: We’ve focused on making Rlinguo enjoyable to use. Get ready for a smooth, playful experience with a dash of data science. - Offline Mode: Whether you’re out in the middle of nowhere or just need a quick break, you can enjoy Rlinguo offline. It works perfectly without a data connection, making it great for people in remote locations. It’s just the beginning of a new era—because who knew learning R could be this fun? Ready to play?
