I've made a remake of popular game "2048", but now you can choose 4D, 5D or even 6D game mode.
Of course it has usual 2D mode and 3D.
It runs in browser: http://www.alextaran.net/webgl/TPo2.html
It's written on pure JS & WebGL, so it works in Chrome (also some people told me that sometimes it works in IE11, Safari and Firefox).
Thanks for any suggestions, opinions, maybe bugreports.
Anyway, it's free and was made just for fun. If somebody likes it - that would be great.
