Kind Words is unusual because of the main interaction. You write letters to real people and receive back encouraging letters in return. Set in a cosy room with soft furnishings and relaxing music, it creates a space in which to find support and friendship with strangers.

"We're all in this together. Sometimes all you need are a few kind words." Says the developer. But perhaps most surprising about the game is its ability to ensure these letters to and from strangers are positive and honest.

Players are incentivised to send helpful response letters by people rewarding favourite letters with stickers that you can collect. This, along with the tone of the space in which you write, and some checking of content by the developer makes the experience much safer than you might expect.

Still, this isn't a game to let your child play completely on their own. But in a shared social space they can enjoy writing response letters to help people they don't know, as well as writing their own notes for others to respond to.
