Escape velocity

closed

Build a machine that gets a marble moving faster than 25 m/s. Gravity is the only free energy you have — everything else you construct.

What the engine checks

A body labelled “marble” must exceed 25 m/s at some point within 10 simulated seconds.

Runs for 10 simulated seconds. Everyone who solves it is ranked by lowest peak energy.

Engine Validation Rules

Evaluation Rule: A body labelled “marble” must exceed 25 m/s at some point within 10 simulated seconds.
Simulation Duration: 10 simulated seconds
Leaderboard Metric: Lowest peak energy
Win Condition (peakSpeed): A body labelled "marble" must exceed 25 m/s at some point.
Allowed Attempts: 0 of 25 attempts used

Every submission is re-simulated on the server so scores cannot be reported by the client.

How to enter

Build a scene in the studio that satisfies the rule.
Label the body the rule names — the scorer looks it up by that name, so it has to match exactly.
Open Enter a challenge in the studio and pick this one. The server runs your scene; your best result is what stands.

Solving pays 50 Atoms, and finishing high pays more once the contest closes. The studio reports how the scene was built; that never decides whether an entry counts, it only decides whether a person looks at it.
