On general worldwide release, we are now getting into the scarcity market. The USA & Brazil never got an official release. This version doesn't even work on a videopac+ or Jopac models of machines. Seems maybe due to falling trade Philips drenched up some old titles as even the gameplay seems to be a leap backwards from the expanded memory games. That Said there was plans to release 4in1row to the US market according to a 1982 pricelist, it never materialised. 4in1 row in Europe however, is reasonably easy to come by, the deprived US market may drive the price up a few quid if bidding on eBay since they never had it the world got smaller because of the internet.
