In today’s daily I was somehow able to play again even though I did not refresh the browser (as discussed in the Refresh = 5k wins topic).
The only thing that I did different than my previous daily runs was that I had to go to the toilet after playing round 1 - then came back and continued playing round 2 and 3. After I finished and went back to the home screen, my daily challenge button was still orange even though I was just told my results for todays daily (which was around 14500 afair).
To not lose the daily, I then just did quickly guess again without trying to get 5ks.
This might also explain why there are quite a lot of cheaters as discussed in Cheaters in Daily? .
