Book of Rrrum is an ESAGaming slot with 10 paylines and a bonus buy option. Volatility is medium to high, and the RTP is 96%.
ESAGaming has kept the game compact: there are only 10 paylines, so the playing field is easy to grasp. The title points to the book-style slot tradition, but no finer details about its content are given here.
Volatility is medium to high, so results can vary considerably. Do not expect wins at an even rhythm: quiet stretches and livelier ones are both part of the game.
The RTP is 96%. It is a theoretical average over a very long period and shows the game's typical return, not the outcome of one session.
The top win is 7,000 times the stake, a clearly high ceiling for a ten-line game. With bonus buy a player can pay for direct access to a special part of the game, but the purchase costs more than a normal spin and adds variance.
It works on mobile. Only use the purchase option if you understand what it does to your stake, and keep your playing time under control.
