Galton Board vs BLACK JACK PROBABILITY
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.
- 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
Galton Board and BLACK JACK PROBABILITY are too close to call on the numbers: across 5 compared parameters — update cadence, ads, in-app purchases and device support among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.
