Book of Lady Slot by Endorphina

Three or more of the red, crown-stamped Book and you're into 10 free games, which is where this one earns its keep. At the start of the round the game picks one symbol at random and hands it the power to expand. From then on, whenever enough copies of that chosen symbol land, position doesn't matter, only the count, it stretches to fill its whole reel and pays across adjacent and non-adjacent spots on the active lines, settled after the normal symbols have paid out. The Book stays wild during the round but won't stand in for the special symbol, so a low-value royal like the 10 or J becoming the expander can carpet a reel and still pay full height.

The round retriggers, and that's the unusual bit. Each retrigger doesn't just hand back more spins, it adds a second special symbol, then a third, stacking up to nine different symbols all capable of expanding at once. Get deep enough and most of the symbol set can blow up to fill a reel, which is a far wider net than the single-symbol Book clones usually offer.

The Book does double duty in the base game too, substituting for everything as a wild and counting anywhere as a scatter to trigger the feature. If you'd rather not chase three Books, the Bonus Pop button to the left of the reels buys the 10 spins outright, and it lets you choose which symbol gets the expanding capacity instead of leaving it to the draw. Pick a premium like the Lady and you're betting on a high-pay reel fill. Bought winnings can't be sent to the gamble afterward, the usual Endorphina catch.

Wins also run through a card gamble, the standard beat-the-dealer flip where you double up to ten times, joker beats all. Sitting separately are network mystery jackpots in Grand, Major and Minor tiers, drawn at random with a bigger bet improving your odds.

The board sets the reels on a deep purple panel in a thin gold border, dropped onto a glossy blue-and-purple fashion runway lined with marble columns and raking spotlights, a red-and-gold logo crowned with jewels above. Premiums are high-society props: an elegant lady, a fluffy white Persian on a red cushion, a black stiletto, a tan designer handbag, sat over jewelled gold 10 J Q K A royals. Glossy and a little camp, which suits a slot built to mark Women's Day.
