How your data is kept safe
Everything here edits content only: games, game files, updates and website settings. Your users' accounts, favourites and what they've read live separately, and this panel can only read them. Every game upload keeps the previous version, so you can roll back in one click.

⭐ Premium
🏦 Bank transfer (VietQR)
Fill these and the Premium box shows your bank details and a VietQR code teachers scan with any banking app. Each teacher gets a personal QR code with the amount and a unique note (like MCG7K2P9Q). Connect SePay (Affiliates & Premium page) and Premium switches on by itself about a minute after they pay. When the money arrives, go to Affiliates & Premium → Record a payment.
💳 Pricing page
Prices are set in Affiliates & Premium → Plans (VND and USD).

💳 Card payments (Stripe)
Plans teachers can buy
Prices are charged in the plan's currency. Keep it the same as your invite program currency so commissions add up. VND has no decimals; USD uses cents (e.g. 4.99).
💰 Record a payment
Card payments are recorded automatically. When a teacher pays you another way (bank transfer, MoMo…), record it here. They get Premium, and whoever invited them gets their reward automatically.

How topics work
Topics are word lists (word, clue, example sentence) that teachers play in the topic games: Last One Standing, Sweaty Buttons, Word Race, Word Fish and Word Hunt. Every public topic gets its own page at /topic/… and goes into the sitemap, so each one is a new way for Google to find you. Approve the good ones, hide spam.
🚫 Blocked words list (English + Vietnamese)
Separate with commas or new lines. A * at the end also blocks longer words (fuck* blocks "fucking"). A topic with a blocked word is saved but waits in Waiting for review.
📥 Add many topics at once
Paste your topics below, or open a .txt, .csv or .json file. Each topic starts with a line beginning with #: # Title | Subject | Ages | Type. Under it, one row per line: word | clue | example sentence | picture link (only the first part is needed). Ages can be grade numbers (3,4 or 6-9) or Pre-K, Primary, Secondary, High school, Adults. Subject is one of the topic categories, e.g. Maths, Science, Geography, Animals. Type is words, questions, sentences or quiz (quiz rows: question | right answer | wrong / wrong / wrong). Leave an empty line between topics.
| Topic | Words | By | Status | Plays | Updated |
|---|
✨ AI topics
Teachers press ✨ Make it with AI in "Make a topic", type what they need (any subject, any age) and get a ready topic with pictures. Keys stay on the server; teachers never see them.
Writes every topic.
Only when the main one is busy or fails.

How to get a key
- Google Gemini (free with daily limits): aistudio.google.com/apikey → Create API key (starts with
AIza). - OpenAI: platform.openai.com/api-keys → Create new secret key (starts with
sk-). Add credit under Billing. - Claude: console.anthropic.com → API keys (starts with
sk-ant-). Add credit under Billing. Auto uses the newest Haiku (fast and cheap). - OpenRouter: openrouter.ai → Keys (starts with
sk-or-). One key for many AIs; some models are free (names end in:free). - Set a monthly spending limit on the AI's billing page, so a surprise bill is impossible.
📧 Email server (every email the site sends)
Confirm-email, welcome, trial, password-reset and campaign emails all go out from this mailbox. Use contact@myclass.games. Many hostings (Namecheap too) block or spam-folder emails sent the simple way, so it's best to send through a real mailbox (SMTP).
How to set this up on Namecheap (5 minutes)
- cPanel → Email Accounts → Create a mailbox, e.g.
contact@myclass.gameswith a strong password. - Next to it press Connect Devices. Copy the Outgoing Server (e.g.
mail.myclass.gamesorserver123.web-hosting.com) and the SMTP Port (465). - Fill in the boxes below: server, port 465, security SSL, username = the full email, password = the mailbox password, "From" = the same email.
- Press Save, then Send test email to your own address.

Email not arriving for a teacher? Go to 👥 Users and press 🔑 next to their name to get a reset link you can send them on Zalo or Messenger.
🖼 Picture & GIF search (for teachers' topics)
Teachers click 🖼 on any word to search pictures, like Baamboozle. It works for free with Openverse and Wikimedia Commons (no key needed). For more and better cartoons, add a free Pixabay key. For real animated GIFs, add a free GIPHY key.
Pixabay: sign up → open pixabay.com/api/docs → your key is shown in the "Parameters" box. GIPHY: developers.giphy.com → Create an App → API → copy the key.
