15 puzzles across 3 themes
Systems thinking is the muscle that asks how does this connect to that? Push one domino — the next one falls. Add one wolf — the rabbits scatter. Every change has a chain.
Gears, dominoes, gates — cause and effect made physical.
Connect gears to achieve target rotation speeds.
Push one. Watch them all fall. Predict the cascade.
Build working logic circuits with AND, OR, NOT, XOR gates.
Race sorting algorithms head-to-head. See which strategy wins.
Mix RGB light beams to create colours. Additive colour theory.
Nodes connected by edges. Pipes, paths, bridges, trees.
Connect pipes to route flow from source to destination.
Colour graphs with the minimum colours. Discover chromatic numbers.
Connect islands with exactly the right number of bridges.
Build trees to explore all possible outcomes.
Navigate cosmic systems with physics-based challenges.
Self-organising systems — ecosystems, markets, games, life itself.
Explore positive and negative feedback. Cause, effect, equilibrium.
Build patterns in Conway's Game of Life. Emergence from rules.
Predator-prey dynamics with wolves and rabbits.
Prisoner's Dilemma vs adaptive AI. Discover tit-for-tat.
Buy and sell as news events move prices. Risk and decision.
About the Systems Division
The five questions parents ask first when their child arrives here.
Systems thinking is the muscle that asks when this changes, what else changes? The child learns to track flow, predict cascades, and see the network behind the parts — the foundation of engineering, biology, economics, and good engineering judgement.
Children who take apart toys to see how they work, who ask 'but what if' a lot, who set up domino runs or marble tracks for fun. Systems-thinkers want to understand the engine, not just the wheels.
Starter puzzles have one chain or one loop. Regulars introduce competing forces or multiple variables. Stretches drop the child into emergent systems where simple rules create complex behaviour — like Conway's Life.
Every puzzle has Show Me and Explain. Speed controls let the child slow time down to watch a single step at a time. There is no time pressure — only the desire to understand.
Yes. Systems are the language of biology (ecosystems), economics (markets), engineering (mechanisms), and computing (networks). Children who play with cause-and-effect early find these subjects feel like meeting old friends.
