I would appreciate any recommendation on these games and puzzles with maple implementation. The purpose is to inspire the math interest of children (say 16-) . Benefits from the assistance of Maple:

1. Learn and build the habit of math modelling: eg by playing with this n-queen problem - https://www.maplesoft.com/Applications/Detail.aspx?id=154482

Children can realize that, for many problems, modelling is doable for them - question formation in math/programming and finding all the constraints - while solution method is simply a small step if done by computer. This is already a big step forward for them and they may enjoy the modelling process. For more math-eager kids, they may start to explore the documentation behind the solution methods.

2. Learn the art of automatic proof by witnessing the efficiency gain by themselves - I don't think I have to explain such to the community here. I note Doron Zeilberger has collected many in such a spirit on his website.

I have read some in the Application Center (eg under the tag game) and by searching here by the "puzzle". Is there some more systematic collection/books? The applications I have seen is mostly on logical/combinatorial problems. Love to see the games/puzzles under a broader range of math fields good for children.

It seems Maple's Sample command cannot handle self-defined distribution well. Check this:

Can anyone please tell me how to remove the box outside of legends? I cannot find where this is documented.

Try this out:
dt:=[2.5, 3.9, 2.9, 2.4, 2.9, .8, 9.1, .8, .7, .6, 7.9, 1.5, 1.8, 1.9, .8, 6.5, 1.6, 5.8, 1.3, 1.2, 2.7];
Statistics[Histogram](dt);

You can see the tickmark for frequency/vertical axis is wrong. The leftmost bin hits somewhere more than 0.8. Option "frequencyscale=relative " does no help. But option "discrete=true" or change some setting about bin, such as bincount ..., can help. It seems a bug? Or my understanding about histogram is not right?
