About

Galton Board

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

Highlights
  • Galton board simulation
  • Adjustable board size
  • Simultaneous simulations on iPad
  • Bar chart visualization
  • Educational tool for probability
  • Demonstrates Pascal's Triangle relation

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!

Verdict

The call

The clearest difference is review sentiment: Galton Board at 60% against ProteinViewerApp's 0%. Galton Board also leads on price (Free vs $4.99) and rating (4.6 vs 3.0). ProteinViewerApp's advantage is update cadence (fortnightly vs every 5 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
