Book of Ra card on Grizzly Slots
Players in Canada can open the session page for Book of Ra slot apart from this catalogue.
Grizzly Slots lists Book of Ra as the Greentube slot for players in Canada who continue at Here2Win Casino. Volatility on the card is high-volatility, and the published RTP is 94.26%. A night in Montreal can finish nowhere near that percentage, because RTP is not a session score.

Book of Ra RTP (94.26%), house edge & 500-spin session math
Book of Ra by Greentube returns a published 94.26% RTP (5.74% house edge) across a 5×3 classic video grid layout and calls for a 250x–350x bankroll buffer in C$ at Here2Win Casino (here2win.com.au).
This Greentube release stands at -0.79 percentage points against the 95.05% studio average across 135 RTP-published titles (rank #124 of 135). The high-volatility slot distributes payouts according to its certified reel weightings. Its 94.26% math model requires a 250x–350x unit-stake buffer to absorb standard variance swings. Players launch Book of Ra in C$ at Here2Win Casino (here2win.com.au) with full HTML5 desktop and mobile parity.

What this slot is
Grizzly Slots states it in one pass. Book of Ra is a Greentube slot. Canadian players open it at Here2Win Casino. This page does not add a rating.
Greentube built Book of Ra. Grizzly 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.
The lines under the title are the preview. The description tag uses the same facts. City, including Montreal, is not a setting in the game.

Studio
Greentube made Book of Ra. 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
There is no second system hiding under the name Grizzly. The slot is not due.
Book of Ra does not store your last session. One evening in Montreal is not the sample behind a published RTP.
Who it suits
A high-volatility slot moves a C$ balance in bursts. Players who want a shorter visit usually cut the stake. Book of Ra will not smooth itself out.
High or very high pace is the rule for the high volatility list.
