I have seen this spreadsheet:
Tues 6-21 (ends at 11:50 GMT)
From two locations, I am trying to play!
Can you see the daily tabs at the bottom of the spreadsheet, clock on the one for Thur - 6-23
And if you don't see the tabs, please let me know and I'll investigate further, It shouldn't matter, but you may try a different browser, someone earlier had a differebt problem with chrome.
