In the pre-release checklist, it says to 'Test your game in 3D mode". What does this mean? What is 3D mode?

~cmgames

It puts the game table into a simulated 3D perspective. Start up a game and the select '3D mode' from the game menu (top right). Then verify that everything works as normal with the new perspective.

In particular, check that elements that have the z-index CSS class set work as expected.

It would perhaps easier for everyone if a developper could define "3d allowed" for his game. I usually don't use it, and I am ok when the table is "flat". But now I have - just for fun - tested a card game project of mine, where I have used a particular high z-index when cards are moved. I was surprised that the 3d effect is good when moving cards: the cards lift off the table and come dowm in their destination, but it is horrible when a card is flipped. I have expected this, because I used some CSS that expects a top-down view (the rotation axis is in the same level as the table, so half of the card disappears; one side is invisible...)
Not everything is fine, though. For some reason some elements were not clickable (refreshing helped), and one animation did not start at all. So, what can be the reason for this? There is just basic functions taken from the studio doc (moving temporary items, call function on end of animation).
Honestly I don't want to spend time on testing everything in 3D when the game is not not intended to be used in 3D mode, and solving problems I do not want to solve.

This is actually possible http://en.doc.boardgamearena.com/3D
I have updated the pre-release checklist for a little more context about this.

Good to know
