Add-on ( poker )

The opportunity to buy additional chips in some tournaments. Some tournaments allow
players the opportunity at a certain point to buy additional chips,
called an add- on. This is different from a re-buy, because usually anyone still in
the tournament can add on, and the opportunity to add-on usually marks the
end of the re-buy period. I was in such bad chip position,
I decided it wasn't worth paying for the add-on.
