Throwables are digital objects that you can hurl at other players. Like an extension of the chat function, these objects have their own context and meaning. A box of tissues to wipe away those tears, fireworks to celebrate a hand, and a floppy fish for disgracing the bad player at your table.
While all remaining players have the option to show their cards, in many cases players with losing hands will choose to simply toss their cards away without revealing them (known as mucking ) if they see that a stronger hand has already been shown.
