About

Galton Board

Explore probability theory with a simulation of the classic Galton board. Adjust board size, send numerous balls through a pin maze, and observe emergent patterns visualized in a bar chart. Ideal for educational purposes, it helps grasp concepts of chance and their relation to Pascal's Triangle.

Highlights
  • Galton board simulation
  • Adjustable board size
  • Simulate over a thousand balls
  • Bar chart visualization of results
  • Educational tool for probability
  • Related to Pascal's Triangle

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!
