Record Breaking is a free browser game. Every level is a real optimisation problem from mathematics, and the target is the best value anyone has ever found, often by researchers with supercomputers or by AI systems like AlphaEvolve.
You drag points with your finger or mouse. The score shows instantly how close you are to the record. Ten points on a level means you matched the world record. On open problems, a better position would be a new record, and the game checks and saves it automatically.
Push the points as far apart as you can. Only the closest pair counts. Each point carries a circle with half the minimum distance: the bigger the circles, the better. This is the classic problem of packing circles in a square.
Make the smallest triangle as large as you can. Every three points form a triangle. Only the smallest one counts, and it is highlighted. If three points lie almost on a line, your value drops towards zero.
Spread electrons on the sphere with minimal energy. Equal charges repel each other. The goal is the arrangement with the lowest total energy. Drag a point to move it, or drag beside it to rotate the sphere.
Keep the longest distance short and the shortest long. The score is the longest distance divided by the shortest, squared. Lower is better. Size and position of the figure do not matter, only its shape. The record for 16 points was set by the AI AlphaEvolve in 2025 and has been narrowly beaten several times since.
Make the smallest triangle large, relative to the hull. Like the triangle problem, but without the square: the score is the smallest triangle divided by the area of the hull around all points. For 14 points the record was set by the AI AlphaEvolve (2025).
