Getting Started
What is 3Cubeii?
3Cubeii is an EdTech SaaS platform that transforms flat texts (speeches, articles, documents) into a gamified language universe. We use AI to extract vocabulary based on CEFR levels and inject them into interactive game engines like Crosswords, Dungeons, and Timebombs.
Do I need to pay to play?
No! You can play as a Guest without an account, but your progress won't be saved. You can also create a Free Starter Account which gives you access to 3 basic games, 5 missions a day, and basic PEDJ tracking.
What is the CEFR Lobby?
The CEFR Lobby is where you choose your difficulty level. Vocabulary is categorized into A1 (Beginner) to C2 (Mastery). Selecting a tier ensures the game mechanics and vocabulary match your current learning stage.
Game Engines
Where can I find the detailed rules for each game?
For complete, step-by-step instructions on how to play Classic Crossword, Fog of War, Tug of War, and other game engines, please check our How-to Guides.
What happens if I fail a game?
If you run out of HP or time, the mission fails. Any words you missed will be recorded in your Weakness Book inside your PEDJ Dashboard for future revenge missions.
Are the games multiplayer?
Currently, all game engines are single-player experiences designed for focused language acquisition. However, your scores are tracked on global leaderboards.
PEDJ Dashboard
What does PEDJ stand for?
Personal Experience Data Journey. It is your centralized command center where we visualize your vocabulary mastery via Radar Charts and Activity Heatmaps.
How do I clear words from my Weakness Book?
Words are automatically added to your Weakness Book if you miss them during gameplay. To clear them, simply click the "Quick Challenge" button next to any missed word. This will launch a targeted revenge mission. Successfully complete the challenge to remove the word from your record!
3Cubeii Nexus
What is Cyber Academia?
Cyber Academia is our User-Generated Content (UGC) playground powered by the 3Cubeii Nexus. It allows educators and creators to upload their own flat texts (like articles or speeches) and let our AI engine instantly transform them into an interactive game universe without any coding.
Who is 3Cubeii Nexus for?
It is designed for educators, publishers, and language training centers who want to create custom, gamified learning experiences tailored to their specific curriculum and students.
