Klondike is a single-player game, so there's no option to invite friends and share resources. It's designed to be comfortably played alone. You may build your unique gameplay strategy and receive various bonuses to advance in your own way :)

However, there is a community you can join - our official Facebook page! There you can chat with other players, keep track of upcoming events, and take part in our lotteries and games for a chance to get a useful reward :)
