Reading the mechanic

The central distinction in Book of Dead is between an ordinary symbol and the special symbol selected for the free-spin sequence. The provider describes a symbol chosen at random before those spins begin. That choice applies for the sequence, rather than being a new choice on every spin. [1]

Expansion is conditional. Regular combinations are evaluated first; the selected symbol expands over the three positions on its reel only when the expansion can create an additional prize on active paylines. Reading “expanding symbol” as “every appearance fills a reel” would miss that condition. The expanded symbols do not have to occupy adjacent reels to form a winning combination. [1]

Three scatters initiate ten free spins, and three or more scatters during the sequence award another ten. A retrigger extends the sequence; it does not establish how often a sequence will occur. This entry concerns the provider page titled Book of Dead, not another game with a similar book motif. [1]

Take it to the paytable

  1. Find the ordinary-symbol award table and the separate expanding-symbol award table. Which combinations qualify before expansion, and which qualify afterwards?
  2. Identify the active paylines. The description makes expansion conditional on an additional prize along those lines; do not evaluate the screen as a count-anywhere game.
  3. Check the feature help for what happens on a retrigger. Does the same selected symbol remain, and which rule states its duration? The public description alone should not be stretched to answer an unstated detail.
