I invent simple version of Game of Y. You play three games of Y at once on one board. Every stone has three features. You can try this game on website http://ranka.mobi/yyy. More in forum YYY on BGG.

Will the game be added in golem? 

It would be better – in my opinion – to keep the original idea of different colours for the 2 sub-games and shapes for the 3rd.

Say the current blue-orange scheme for the 1st subgame (external circles), white-black for the 2nd (internal circle) and a small shape (light blue square / light orange circle or similar) for the 3rd subgame.

I’ve inverted my own version 

The primary player places a red, green and blue 1/3 counter in 3 different spaces (if available else anywhere)

The secondary player places cyan,magenta and yellow in the same method

Colours can’t be placed with opposites (each space has a sub space for red/cyan, green/magenta and blue/yellow)

Win with 2 colours to win
