Quiz Goblin lets you import your Google Slides or PowerPoint to create interactive slides. A presenter runs the game from one screen while players join on their own phones or devices using a 4-letter game code, and you can layer live questions, polls, word clouds, and hotseat rounds on top of your presentation — including questions generated on the fly using AI.
Quiz Goblin works like a live game show. There are two roles — the Presenter who controls the game, and the Players who join on their phones.
Opens index.php on a large screen or projector. Controls all game flow — starting questions, showing results, and advancing slides.
Players open player.php on their own phone or tablet and enter the 4-letter game code shown on the presenter's screen.
Answers, scores, and reactions all update live for everyone in the room. No app download needed — everything runs in the browser.
The presenter can generate quiz questions automatically from the current slide content using built-in AI (requires your own Anthropic API key, entered per game).
The presenter opens index.php on the main display. This is the control centre for the entire game.

yoursite.com/play/player.php). You can also scan the QR code shown on the presenter's screen.The presenter can switch between different interactive modes at any point during the game.
A multiple-choice question with 5 options (A–E) and a countdown timer. Points are awarded for correct answers, with a speed bonus for fast responses.
Players vote on a question with no right or wrong answer. Results are shown as a live bar chart. Polls do not affect scores.
Players type in a free-text word or short phrase. All submissions are gathered and displayed as a word cloud on the presenter's screen.
One player is put in the hotseat. The rest of the audience votes thumbs up or thumbs down in real time. Great for discussion or debate moments.
During any round, players can send emoji reactions (🎉 😂 😮 👏) that float up on the presenter's screen. This adds energy to the room without interrupting the game.
You can upload a .pptx file directly from your computer to use as your slide deck.
If two presenters are running sessions at the same time, each gets their own unique game code and their own uploaded file. They do not interfere with each other — each player is connected to exactly one game code.
Quiz Goblin can automatically generate a quiz question or poll options based on the content of the current slide. This uses the Anthropic Claude API and reads your slide using your browser's screen-share feature.
Generated questions have exactly 5 answer options (A through E), one clearly correct answer, and are kept concise so they're easy to read on a phone screen.
Scores are tracked automatically throughout the game and visible to the presenter at any time.
| Action | Points |
|---|---|
| Correct answer (slow) | Base points awarded |
| Correct answer (fast) | Bonus for speed — the faster, the more |
| Wrong answer | No points |
| Poll / Word Cloud / Hotseat | No points — participation only |
The presenter can open the Scores panel at any time to see a full live leaderboard. Players also see their own rank on their device after each question.
The presenter can click Reset Game to wipe all players, scores, and answers and start fresh. This is useful between groups or class periods. The same game code can be reused. Resetting also removes any saved AI API key.
At the end of the game, the presenter can reveal the final podium — a dramatic animated reveal of the top 3 players.
After the podium, you can reset the game to run another round with the same or different players.
Yes. Players can join at any point. They will start with zero score but can participate in all future questions from the moment they join.
They can simply reopen the browser and re-enter the game code and name. Their score is preserved on the server.
Yes. You can paste a Google Slides URL into the slide viewer, or just skip slides entirely and use the question and poll tools on their own. The game works fine without any uploaded content.
There is no hard-coded player limit. In practice, performance depends on your server. For classroom use (up to ~40 players) it should run smoothly.
No. Each game code has its own isolated database. Two sessions running simultaneously with different codes are completely independent.
Click the Reset Game button, or click New Game in the game code badge area to generate a new code. Players will need to re-join with the new code.
Uploaded .pptx files are stored temporarily and automatically deleted after 6 hours. They are not shared between games and are not accessible to players.
Your key is stored server-side only for your current game, tied to your game code, and is automatically removed after 3 hours or when you reset or start a new game. It is never shown to players or shared between games. See the disclaimer in the AI Question Generation section for full details.
