The Host

The Host explains the game.
You can use the "what is this" section of this website to explain the game, or whatever paraphrasing you think will be best understood by your audience.
The Host should read all the rules on http://snapshotstorytelling.blogspot.co.uk and ensure she is clear on how they work, since she will probably be the only one who has read them in full!  


The Host makes the first move. For the first move only, you can ask as many questions as you like.
By making the first move, you choose the first image and ask the first questions.
Choosing the first image enables you to set the feel of the game and plants the seed that will grow into the story. Therefore, choose your image with care! You want something that is provocative and intriguing (to you at least).Asking the first questions pushes the participants in the direction of answering them. They will probably form the basis for what the game is "about". Ask questions you're really interested in seeing the answer to!
If you want a quick start, use these sample starter images.
Two to four questions is about right for the first move.

The Host decides the venue.
You'll need to choose a website where images can be posted and commented on, where some form of "voting" in the form of +1s, likes or similar is available. You ideally want the power to moderate so you can tackle disruptive posting.
Of course, you want somewhere that your desired participants find conducive - if none of them are on Facebook then it's probably best not to put the game there!
Consider whether to pick a venue where others can freely post, one where they have to be invited or one where only you can post (meaning others will have to send their contributions via you). Either way it's a good idea to retain editorial rights so you can make sure rules text is included where needed, and errors are corrected.

The Host decides how quickly the game will play by setting the discussion duration.
Pick one that will work for the level of participation that you and your friends can manage.

The Host decides who will make the next move.
You'll probably have a group of friends in mind to play the game with you. You're well within your rights to invite only them to make moves early on. This will enable you as a group to create the kind of game you want. If others join in, then this will give you time to see whether you enjoy their contributions and invite them to play if you want to.
When you invite someone to make a move, it's a good idea to give them a deadline to make it, so that the game doesn't stall. You should also link them to the making a move section of this website.

The Host announces the results of each round.
This duty will mean being reasonably punctual in turning up and reading through the various contributions on a post, and doing some simple maths.
You'll need to be aware of what previous interpretations have been accepted as true, because new interpretations cannot contradict them.

The Host keeps a post each updated with the true interpretations and the questions posed.
You may want to pin them to the top of your chosen website, or link to them in each new image post.

The Host decides when the game ends.
 Remember that the game cannot end until at least half of the questions posed have been answered, and ends automatically when all the questions posed have been answered.
