Descripción

Originally conceived in 1894 by Galton, the board consists of countless balls traversing down through a maze of pins. At every pin, they have a single choice: go left or right.
Although the possibilities seem limitless, a pattern soon emerges. But how does this really work?

This app is a simulation of the famous Galton board and is intended for educational purposes. You can adjust the board size, and send over a thousand balls bouncing down the board. On iPad you can even run multiple simulations simultaneously with multiple windows.

The results are visualized by a bar chart. The Galton Board is closely related to Pascal's Triangle, Newton's binomium and probability theory in general.

For experiment fidelity and performance, the balls do not collide with each other.

I hope this app helps people grasp chance at least a little bit better.
Love the app, or have improvements/suggestions? Let me know!

Versión 2.0.1

We've polished the balls, so they zoom down the board smoother than ever.

Simply Great

It’s very didactic and great if one wants to explain children how normal distributions and Pascal triangles work.

Question to the developer: is it an actual 50/50 chance of going left or right, or it’s programmed to follow certain pattern?

Hi LaloMexico, the physics simulation features an animated noise field (without which, balls would simply balance unrealistically on the top pin and never fall to the left or right). While I don't have explicit control over the distribution of this noise field, for all intents and purposes there is a 50/50 chance of a ball dropping left or right of a pin (as shown by the resulting graph).
