There are two accepted forms for possessive singular nouns that end with an s:

Add an apostrophe (') after the existing s at the end of the word:

• ass'

Add an apostrophe s ('s) after the existing s at the end of the word:

• ass's

. Examples:

"The farmer pulled out the ass' feed and put it in the tray".

"The farmer pulled out the ass's feed and put it in the tray".

yes almost all game are safe but don't throw the dice if it has one.

Actually, kids find loopholes in saying bad words, one example; ass(s) which comes out as ass.
