i've encountered this issue when playing saheric slide where, if i click the tiles too fast, one of them will move into a space that is still occupied by another tile and becomes stuck, thereby making the game unwinnable. this is especially frustrating when i'm powering through the last few moves of a game - the game breaks, and i have to start over.

i've noticed this problem for at least a couple years now? basically since i started playing the game every now and again. i would theorize that it's been around since the game was added to the site.

i have encountered this issue in both safari and chrome. i've tested it just now and it doesn't seem to be an issue with double clicking. double clicks will either register as clicking just once, or clicking the same tile twice so it moves and then moves back to its previous position.

but if i click a tile too quickly after having clicked the previous tile, it will move diagonally and then everything will get all janked up. here's a picture that hopefully explains it a bit? (click for full size)
