i have discovered a very interesting bug in this game on my end.
the cards are in these weird stacks where i can take any of the top four cards off and put them in the foundation. if i remove all of the seemingly inverted cards, then a normal column is revealed underneath where i can no longer rearrange the cards at will (which as i understand it, is correct).
i tried both the browser and downloaded version. eventually i figured out the problem: my monitor usually refreshes at 240 hz, and this actually breaks the game. if i set the monitor to 60 hz it appears to work fine.
hopefully i'll be back with some more substantive feedback later.
