STEM through play
Games where fractions, forces, orbits, algorithms and molecules are the mechanics, not the wrapping paper.

Games that make systems visible
Some games are especially good at making structure legible. These picks give repeated contact with congestion, sequence, capacity, optimization, or trade-offs, and may help players notice how one change in a system can ripple outward through the rest of it.
- Who it is for
- Players who enjoy seeing how rules connect, where bottlenecks form, and why one decision changes the whole model.
- What is inside
- Five games about networks, sequences, logistics and orbital mechanics, from a five-minute transport puzzle to deep factory and rocketry simulations.
- How we chose
- The core loop must show cause and effect: a change in one place visibly ripples through the rest of the system.
- Ordered from lightest to heaviest so a player can start small and step up when the appetite is there.
- Every pick can be explained without the game: bottlenecks, capacity, instructions, throughput, orbits.
- Meaningfulness ratings reflect how clearly the mechanics expose the system, not how realistic the setting is.
- Logic & strategy
