Formats, and how tiles open
Two decisions shape an event more than every tile in it: what shape the board is, and how tiles become playable. They are independent — any format can use any reveal policy — and together they are the difference between a week-long grind and a nightly race.
The shape of the board
The format decides how the board is scored and what the create form asks you for next. Everything else on this page composes on top of it.
A classic board is a true square, so “N of 5” means exactly 25 tiles and the count can never change. Everything else is a task list of any length, which is also the only kind of board a bulk spreadsheet import can grow. If you are generating a hundred tasks, that decision is made here.
How tiles open
Independent of format. The event-level reveal switch is still the master gate — while a board is hidden, nothing is visible and none of these engines run, so you always arm a board deliberately.
Bounty and interval boards reward whoever happens to be awake. On a clan spread across the world, that is a real advantage handed out by the clock rather than by play. Rotating windows soften it — an open tile stays open for the length of the window, so a sleeping player still gets a shot at it.
What a completion is worth
Three modifiers, all points-mode only, all frozen into the completion the moment it happens — so a change you make later never rewrites history.
Missions: surprises mid-event
Missions are tiles authored up front and held back — announced from their own pool while the rest of the board stays visible. They are independent of the reveal policy, so a plain all-visible bingo can still have them.
Drop them by hand when the board goes quiet, on a fixed interval, or on a per-mission schedule. Each mission carries its own scoring: its own lockout, bonus, decay and expiry, set per tile rather than for the event.
They are the cheapest way to wake a board up on day five, which is the day every long event needs waking up.
Choosing, in one page
If you know the feeling you want, this is the shortest route to it.
Whatever you choose, the tiles themselves are the same job: see Building a board that tracks itself.
Format is fixed at creation but changeable afterwards from the event’s Overview tab; reveal policy and the scoring modifiers can be changed any time before the tiles they affect are revealed.
