Weird 7 Card Stud Question

In 7 card stud, if there are 9 people at a table online what happens if everyone checks though and everyone is still in the hand at the end thats 63 cards? because at PokerStars they put 8-9 people at a table for 7 card stud and if you think either way you dont have enough cards, i asked someone else and they said something like a community last card or somthing can anyone answer my question thanks?

It's 8 people max per table.

If all 8 go to the river, the river card is dealt face up on the table and all of the players 'use' it.

It highly unlikely that would ever happen (especially if you're ,at least, an average poker player) but in that once in a blue moon it does, the dealer does what Dorkus said. When was the last time (or any time) you saw more than five players still in the hand for Hold em all the way to the river?

Ive seen a screenshot of it posted online....... LOL the lower stakes at pokerstars do have 8 players going all the way!
