<p>Book of Christmas Eve opens with its familiar Book symbol pulling double duty as Wild and Scatter, then shifts the action into a free spins round where a chosen symbol expands and winning combinations can pick up multipliers of up to x5. The base game follows the traditional 5-reel, 10-line Book of format, but the darker Santa theme and the restriction of Book symbols to the middle reels give its bonus chase a slightly different rhythm. It is a straightforward seasonal rework with enough added punch in the feature to stand apart from a standard clone, capped by a max win of x20,168.</p>
