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 in-app purchases: Galton Board at none against Bernoulli Trial's 8. Galton Board also leads on ratings volume (44 vs 1). Bernoulli Trial's advantage is update cadence (every 3 weeks vs every 5 months) and rating (5.0 vs 4.6). On price, ads, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bernoulli Trial holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Galton Board has 44 ratings behind it against 1, so its average is the more settled of the two.

UpkeepUpdate frequency

Galton Board ships an update every 5 months, Bernoulli Trial every 3 weeks. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
