MindBubble — collaborative mind mapping

Teachers create a board and share a 6-letter code with their class. Students join instantly — no accounts, no installs — and everyone collaborates on the same canvas in real time. Boards can be shared as a live read-only view or projected directly in presentation mode.

Learning Wall

Teachers build an interactive canvas with drawing tools, shapes, text, sticky notes, polls, randomizers, and a clock, then share a join code so the class can follow along in real time. A wall can be a plain canvas, or a Presentation — upload a PowerPoint file and it's converted into slides the class can follow along with. Each student can privately annotate their own view with a pen, highlighter, or marker; their marks are visible only to the teacher, never to other students, and aren't saved once the session ends. A wall stays viewable only while the teacher is actively connected.

Classroom games

Alongside MindBubble, the platform includes a growing set of teacher-led multiplayer games and single-player practice activities:

• Globle — a geography guessing game where students try to identify a mystery country using a 3D globe. Distance hints narrow it down with each guess. Supports whole-class multiplayer with a live leaderboard. The win screen shows the country's flag and a short educational fact.
• Times Tables Blitz — students race through multiplication questions in 60 seconds. Teachers choose which tables to include; multiplayer runs the whole class simultaneously. Solo play banks a bubble in an on-screen tank for every correct answer, released in a celebration burst at the end.
• Tell the Time — students read an analogue clock and submit the time. The teacher controls the pace; three difficulty levels from o'clock to 5-minute intervals. Solo play banks a bubble in an on-screen tank for every correct answer, released in a celebration burst at the end.
• Maths Blitz — addition and subtraction questions with adjustable number ranges and mixed operations. Available as a solo streak challenge or whole-class race. Solo play banks a bubble in an on-screen tank for every correct answer, released in a celebration burst at the end.
• Spelling Blitz — students pick the correctly spelled word from multiple options in a race against the clock. Play solo, or run a whole-class multiplayer race using built-in word lists or a list a teacher uploads themselves. Solo play banks a bubble in an on-screen tank for every correct answer, released in a celebration burst at the end.
• Type Ninja — falling letters and words that students pop by typing before they reach the bottom, across increasingly difficult waves. Play solo, or run a whole-class multiplayer round using a teacher's custom word list.
• Pattern Builder — students spot what's missing in a visual pattern — colours, shapes, animals, or letters — across a growing set of themed worlds and levels. Play solo, or run a whole-class multiplayer round where the teacher tracks levels cleared on a live leaderboard.
• Code Maze — students drag directional blocks — up, down, left, right — plus repeat loops and if/else/while conditions into a sequence to guide a robot through a randomly generated maze, across eight worlds of increasing difficulty and a target block count to beat. The Power Grid world adds switches, doors, and a battery-powered teleporter to unlock. Solo play only.
• Quiz — teachers create multiple-choice quiz packs with custom questions, colours, and emoji, choose from a library of built-in packs, or share a pack privately with a group of colleagues using a group join code. Run a live quiz with the whole class.
• Poll — teachers ask the whole class a quick poll question with a join code and QR code, then reveal the live results. Students vote anonymously with no name required.
• Wordle — a 5-letter word guessing puzzle for individual practice, with a win screen showing the guessed word and confetti.
• Word Search — a timed word search puzzle for individual practice, with multiple grid sizes to choose from.
• Sudoku — number puzzles at three difficulty levels targeting Year 3 (Simple 6×6) and Year 6 (Medium and Hard 9×9), with a timer, notes mode, and undo.
• Bubble Float — a free-play, sound-reactive bubble display for the projector; bubbles bounce and jump in response to microphone input, and can be popped or dragged around the screen.
• Pixel Art — a free-draw pixel canvas activity for creative sessions.

Achievements

Each single-player game has its own set of achievements that unlock automatically as you play. A toast notification appears when an achievement is earned and badges are shown at the end of each game. All achievements are tracked per device using browser local storage — no account is needed.

Rewards Shop

Students earn points automatically for completing solo games, and can spend them in the Rewards Shop on cosmetics — a colour, title, badge effect, or border that shows next to their name in every multiplayer game — plus a handful of exclusive site themes just for their own device. Points and unlocks are tied to an anonymous device ID rather than an account, so nothing personal is required to take part.

Why I built it

Existing classroom tools are often expensive, require student sign-ups, or aren't designed for whole-class use on a projector and shared iPads. Everything here is free, works instantly in a browser, and keeps student data in Australia.
