Five Tribes???

[MeatAndBreath]

My first thought was chess, too, since e4 is a classic opening move.

Another thought would be Trains, where E4 would be a reference to the Japanese E4 trains. (I think Trains is a Japanese game, too, right?)

The image file is called "Enigma_March2"

It could be enigma just means the riddle of the image, but could also mean the game Enigma?

Interesting - the description does mention 4 areas of problem solving, so there could be something to that.

In any case, please don't be chess. Nothing against the game, but aren't there enough places to play chess already?

Alhambra?

^^^Well, seems like a good guess. 4 different currencies and what was it Kaissa Chess (and games) bringing it to Greece?

Whatever it is, can I sign up to be beta tester?

Need I say more. If it isn't based off of the top character and diamond, along with a similar typeset"4", or as in 4 currencies, we could make a compelling argument for it.
