If I click the "Send score" button after completing a game twice before the pop-up loads I get two messages saying I've completed the game "1/10" and then "2/10" times.

I am having the same problem. I accidentally double clicked the send score button, and as a result it sent the score twice. This has happened a couple of times now. I am using Chrome. 😕

Can confirm this still happens. Whoops!

I came in here to say the same thing. My finger twitched and I got two notices. So I tried to verify it by clicking 3 times on my next game and got 3 notices plus the scores/sP for it. I'm using a firefox browser.

I think this is just a thing that's happening sometimes. I'm 100% sure I didn't double click, but just now it counted my score twice.

I'm also having some trouble sometimes with the shuffle button, it will shuffle the tiles a few times before stopping even if I only hit the button once.

I'm getting the same thing; multiple clicks, multiple scores sent. There seems to be a longish delay for me between clicking the Send Score button and the pop-up appearing.
