They did continue participating but it's true that this became a sort of electric train where daddy buys it for the children and ends up playing the most with it.

The trading game did not capture their interest further than watching colourful flashes for a few minutes. It's probably too complicated for their age and hard to understand without knowing some basic financial markets knowledge.

However I used the same device to make other more appropriate games and keep them involved. I could ask them what game they would want, and I would make most of it but involve them in the parts of the code that can be meaningful to them. I found that while they like understanding how it works when I walk them through some small bits of code, writing code (even heavily assisted) is still daunting at their age so they prefer tools like MIT scratch.
