Functioning Boolean Computer Explanation?

I don’t understand the way boolean gates can be created with Turing Tumble.

Hi @s020031: I’m not sure I understand the question. Can you elaborate? There are probably many different ways of expressing logic gates. One done by @Florentin is AND Gate (standard size simulator) where he demonstrates an AND and a NAND gate (on a standard board). Another demo/design Binary Modular Division is based on use of XOR (using a larger board and more pieces). Is that the sort of thing you had in mind?

I don’t understand how the marbles can carry the value of a one or a zero. I am used to ball computers more like this:

If the balls fall through the circuit one at a time, how could you make a gate? Don’t they need 2 inputs, each of which have either a one or a zero?
