Description

Chaos and order

This app is a digital replica of the Galton Board, a device designed to demonstrate the central limit theorem. 

Just put your phone upright, you can watch how the balls fall, hit pegs, take different paths, and eventually fall into different bins at the bottom. 

In the end, you will find the bins in the middle hold more balls than those on the sides.

It’s not Pachinko!

This is a digital rendition of a device that lets one visualize the mathematical concept of a “Bell Curve.” There are some reviews for this app giving low marks, complaining about it not being fun or having scores, that it’s just balls falling down - well, a Galton Board isn’t meant to be a game, it is “just” balls falling, but in an elegant way that can be used for education. Maybe they thought it was a Pachinko game, which looks a bit similar?
I like it (but I’m a weirdo that actually went in search of a Galton Board app). It would be great if the makers added a setting for it to act as if the board was perfectly upright, as it seems very sensitive to how you hold your phone. Also, perhaps adding a slightly faster speed (if you want to show how the randomness ends up in the same ordered bell curve almost every time).
Despite my geeky review, it is also fun just to watch, the cascading balls bouncing off pegs is rather mesmerizing!

Thanks for liking it

Huh?!

I opened the ap. The beads fell. I turned it upside down and poured them back. There is no ‘next’ no ‘re do’ no ‘score’ no levels of difficulty or any type of instruction button. It just pours beads back and forth.
Have you the developer, actually attempted to play this? What is the point of the game? Am I missing something? Where is the “idea of normal distribution?” You have a center drop of beads that can’t be changed. Objects that they fall on, that are unmovable. Target slots that are fixed. The beads fall predictably, depending on the tilt of the device you are using What is the goal?
This just looks like somebody who wanted an ap, (to get money from ads), but was to lazy to go through the work of actually developing one.

You have changed your description, but the results are the same

Comment after developers response.
No ap makes me “feel bad.”

Hi Dave, Thanks for your review, I appreciate that. Well you got me. When I re-think about it, you're right, I totally missing the point in this app. It makes you feel bad, sorry about that man.
I will reconsider the whole idea of this app.
Thanks again for your honest.
