Book of Dead feature table
| Element | Published rule |
|---|---|
| Grid | 5 reels × 3 rows |
| Paylines | 1–10 adjustable |
| Trigger | 3 book scatters award 10 free spins |

| Book | Acts as both wild and scatter |
These published rules define a five-reel game with adjustable paylines and a feature centred on a randomly selected expanding symbol.
Expanding-symbol free spins
Expansion needs a qualifying condition
In the free-spin feature, a special symbol is selected and can expand when it appears under the game’s rules. Expansion changes the final reel occupancy for that result. The cited configuration uses three book scatters to award 10 free spins and selects one expanding symbol for the feature.
Worked mechanics example
For example, an eligible selected symbol can fill its reel positions before the adjustable paylines are evaluated. Expansion describes the screen change; the paytable establishes the result.
‘Expanding’ describes a rule-based display effect within the feature.
Book of Dead and Starburst both use expansion language, but Book of Dead assigns a symbol to its free-spin feature while Starburst expands a wild during a respin.

| Book-style feature game | How do scatter and selected-symbol rules work? |
| Cascading game | How are replacement results and multipliers handled? |
| Anywhere-pays game | What symbol count qualifies anywhere? |
Book of Dead centres on a dual-purpose book symbol, adjustable paylines and a selected expanding symbol during free spins. A cascading game centres on replacement results after a win, while an anywhere-pays game counts matching symbols across the screen. These rule sequences provide a practical basis for comparing the three formats.
Theme changes the presentation; the grid, win rule, feature trigger and multiplier treatment explain how each format plays.
Practical reading habits
How the feature changes the screen
The book symbol has two roles: it can substitute as a wild and it can act as the scatter that starts free spins. Once the feature begins, one symbol is selected to expand. The resulting round is read in two stages: the selected symbol fills eligible reel positions, then the adjustable payline rules determine the final result.
This sequence makes Book of Dead distinct from Starburst. Starburst expands a wild during a respin, while Book of Dead assigns a selected expanding symbol to its free-spin feature. Both use expansion, but they apply it at different points in the game.
