Mandelbrot Playground
Draw your own weighted dice, test your luck, and see the chances of their totals as you add more dice.
Weighted Dice
Build a function one derivative at a time. Compare Taylor approximations using the car analogy.
Taylor SeriesTwo players. Four dimensions. Select a piece, switch 3D slices, and plan a move across an 8×8×8×8 chessboard.
4D ChessEight 3D block shapes in a 10×10×10 volume. Move, rotate and drop to clear complete horizontal layers.
3D TetrisDraw and label handwritten digits, choose hidden layers, and watch a real neural network learn through its connections.
Neural Network Lab
Solve math to earn spells in a real-time wizard arena. Host a 5–20 minute match for up to 20 players.
Calcula: Math Royale
Hide a 3D space fleet in a 10×10×10 sector. Spend five action points on attacks, scans, and tactical probes.
Void Fleet · 3D Battleship
Mechanics of Materials
Experiment with forces, structures, beams, and trusses.
Orbital Mechanics & Space Flight
Launch rockets, explore orbits, and build across the solar system.
Catch cargo, trade momentum and build a skyhook network. Progress from Earth and the Moon to worlds with very different gravity and atmospheres.
TetherDesign the rocket, program its launch and plan the orbital transfer. Three specialists must solve one interplanetary mission together.
Houston We Have A Problem
Physics & Engineering
Explore motion, controls, electricity, fields, and the geometry of space.
Grab a joint, choose a starting position, and watch the motion unfold beside its phase-space curves.
Double PendulumDrag shapes into a blowtorch. Watch infrared heat spread through materials, cross touching surfaces, and slowly escape.
Heat Tank
Trim two sails and steer a top-down sailboat through a slowly changing wind field.
Windward
Biology, Chemistry & Health
Explore living systems, molecules, nutrition, and evolution.
Pour 3D liquids, compare metals, and investigate pH, precipitates and reactions in a virtual chemistry lab.
Kitta's KhemistryMusic & Rhythm
Build rhythms, explore tuning, and set up a live sound system.
Harmonize a given soprano in five levels of SATB challenges, or compose freely with live figured bass and four-voice playback.
Proper Part WritingCompose in pairs, then match real recordings to classmates’ notation. Teacher settings, shared music editing and guest joining.
Melody Makers
Systems, Strategy & Sustainability
Connect networks, manage resources, and see how small decisions shape a system.
Begin as a dictator. Build a democracy or claim an imperial crown, watching human rights, equal rights and wealth distribution change.
Crown or Commonwealth
A fixed 100 gold coins. Welcome merchants, grow the supply of goods, and watch prices and gold purchasing power change.
Hundred Gold
Govern for 100 years. Compare compounding growth against credit busts, employment shocks and lost purchasing power over 400 quarters.
Brazen KeynesMine classroom tokens, trade possessions, and watch personal ledger copies converge. Visible SHA-256 hashes, nonce guesses, forks and consensus.
Chain ReactionLead government or an industry. Coordinate research, climate policy and deployment, one quarter at a time. Guests can join by room code; adult accounts host.
Climate TransitionGrow an island civilization. Specialize and trade, be self-sufficient, or compete—and see how your choices shape every city.
Common Shores
