What this slot is

Boreal Slots keeps Book of Secrets Extra on a Canadian host so the wording stays in Canadian English: slot, player, C$. This one does not borrow their sentences. Same brand on the button, Here2Win Casino, different page.
SYNOT Games built Book of Secrets Extra. Boreal Slots does not re-rate the math and does not add stars. If volatility is what you screen for, use that label and the high-volatility list. A feature either triggers in the session or it does not.

Studio
SYNOT Games made Book of Secrets Extra. No star rating is added on top. The figure, if the card has one, is the published RTP and nothing else.
What a session does
Keep the session smaller than the urge to continue. Book of Secrets Extra will not remember that you were careful last time.
Pick a C$ limit before Here2Win Casino loads the reels. A longer catalogue does not make this slot kinder.
Who it suits
No volatility label was on the card, so this page will not invent who Book of Secrets Extra suits. What is known is the studio, SYNOT Games, and that play continues at Here2Win Casino.
