I stumbled across this one by chance when browsing the Squwaka website: https://matchboss.com/.
I couldn't see it mentioned anywhere when I searched the forums. Out of interest, Squwaka recently acquired OFL so this might belong in the OFL forums but I'm not clear who's running the game so I've posted here first. It's certainly not branded like OFL is.
Coming next month (5th Sep according to a countdown clock on the front page), it looks like a super-6-style competition but you pick MotM in all 10 PL games. Scoring done by Sqwaka; a quick glance at the rules would indicate attacking players may dominate?
Free to enter, only UK & ROI residents eligible. Every gameweek, a possible £50K jackpot if you get all 10 right (rather unlikely I would imagine). Also, I think every gameweek, a top 20 leader-board sharing a (unspecified size) cash prize pool. And spot prizes for some random table places.
