4 Player Chess issues ?

last few days I have been trying to improve my game playing bots and variants 

/ with the bots I am currently working my way through the available "Advanced" players 
/ as I am looking for the review to learn from them I can only do one per day, played or saved 

/ the variants were fun, a welcome change, especially the "Chess960" 
/ but what is up with the "4 Player Chess" though ? 
/ they do not show up in games history and can apparently not be reviewed 
/ have not seen one (yet ?) in "Open Challenges" either
/ nor does one get the corresponding achievements for playing the games 
/ "Dangerous Intersection" and "Battle Royale" 
/ as I did recieve those for the other variants 
/ looking for a explanation on the forums did not help as they are many and confusing

/ so what next ? stay with the bots and try and improve my "Rapid" rating or ...
