Word Codex is a joyful spelling and vocabulary adventure designed for little learners ages 3–7. With colorful visuals, friendly characters, and playful sounds, children explore words at their own pace — no reading required to get started!
🔍 Discover Mode
Spin letter wheels to find hidden words! Watch as your child's eyes light up when three letters come together to form a real word. Every discovery earns points and unlocks new achievements.
📚 Learn Mode
Three difficulty levels grow with your child:
• Easy – Drag and drop letter tiles into place
• Medium – Tap the correct letters from a fun grid
• Hard – Type answers on a child-friendly keyboard (no autosuggest or autocorrect)
📖 My Book
Every word discovered is saved in a personal word book. Tap any word to hear it spoken aloud and celebrate how much your child has learned.
🗺️ Map & Tiers
Watch your child level up from Beginner all the way to Codex Master across 6 exciting tiers. Points earned in every mode count toward the next milestone.
