Book of Kingdoms®

Book of Kingdoms is the hybrid slot in PragmatikPlay's book lineup — it fuses the book-slot branding with a Money Respin mechanic on a 5x3, 25-payline grid. 96.69% RTP, medium volatility, 20,000x max win. The 20,000x ceiling is the highest in any PP book-adjacent title, funded by the Money Respin feature rather than the traditional expanding-symbol mechanic.

The Money Respin triggers on 5+ Silver Coin money symbols. Three respins begin, coins lock in place, and each new coin landing resets the counter. Values accumulate and pay on completion — the same Hold & Spin logic as Wolf Gold's jackpot respin. The Book of Kingdoms symbol acts as a wild in the base game. The hybrid nature means this is not a traditional book slot despite the name; the expanding-symbol mechanic from the book format is secondary or absent — the Money Respin is the headline feature.

Medium volatility makes this one of the most session-friendly high-ceiling slots in the catalog. Base-game dry patches rarely exceed 20-25 spins. The money symbol trigger requires 5+ coins to land simultaneously — that threshold is the gating event, and at medium volatility the base game regularly delivers 2-4 coins before the 5th arrives, building tension without the punishment of a high-volatility base game.

Against Wolf Gold (medium volatility, 2,500x, same Hold & Spin mechanic): Book of Kingdoms offers an 8x higher ceiling at the same volatility band. Against Wild Wild West Gold (high volatility, 10,000x): Book of Kingdoms matches half that ceiling at friendlier session terms. At 96.69% RTP it is also among the top-five RTP slots in the PP catalog. The name is misleading — think of this as a medium-volatility Money Respin slot, not a book slot.

Verdict
The best medium-volatility Money Respin slot in the catalog. 96.69% RTP and a 20,000x ceiling in the same slot is a rare combination.
