The new throwable is out today. Just a way to help your opponent cool off, at least visually.
The water bottle is available to any player who plays three Grand Tour sprints. Or, who plays three knock out multi-table tournaments.
The water bottle is available for the next two weeks only, so you’ll need to get your skates on (or get on your bike in the case of Grand Tour).
But once you complete those, you’ll find the water bottle along with all your other throwables when you next log in.
And, as always, if you don’t want to see things flying across the table, at you or anyone else, you can turn them off in the settings.
