Eye of Ra Feature

• The Eye of Ra feature is triggered when three or more Eye of Ra symbols appear anywhere on the reels. The Eye of Ra symbols are then replaced by a randomly-selected symbol, excluding Book symbols.
• The randomly-selected symbol expands to replace all symbols on all reels on which it appears to pay for 3, 4, or 5 of a kind on any active payline regardless of reel position.

Free Spins Bonus

The Free Spins Bonus is triggered when three or more Book symbols appear anywhere on the reels. These symbols can appear on every reel.

• At the start of the Free Spins Bonus, one of the symbols, excluding the Book symbol, is randomly selected as the special symbol for the duration of the bonus.
• When three or more special symbols appear anywhere on the reels, special symbols expand to replace all symbols on that reel and form winning combinations on active paylines.
• Special symbols contribute to winning combination only after expanding.
• The winning combinations do not need to be aligned to the left and the symbols do not need to be positioned on consecutive reels.
• The Free Spins Bonus is retriggered when three or more Book symbols appear anywhere on the reels during the bonus.

• The bonus can be retriggered multiple times, up to a maximum of 250 free spins per bonus.
• Free spins are played at same line bet and same number of paylines as the triggering spin.

Rules

• Misuse or malfunction voids all pays and plays.
• All line win symbols must appear on a played line and on consecutive reels, except Eye of Ra Feature where reels do not need to be consecutive, beginning with the far left reel.
• Only the highest winner is paid on each payline. Line wins are multiplied by the line bet on the winning line. Coinciding line wins on different paylines are added.
• Only the highest scatter win is paid per Book symbol. Coinciding scatter wins from different Book symbols are added. Scatter wins are multiplied by the total bet.
• Scatter wins are independent from line wins and are added to the total amount paid.
• Bonus wins are independent from line wins and are added to the total amount paid.
• The Book symbol is also a Wild symbol that substitutes for all symbols except the Eye of Ra symbol and the special symbol that is selected during Free Spins Bonus.
• Wild symbol appears on all reels in the base game.
• Wild symbol appears on all reels in the Free Spins Bonus.
• Wins are shown in currency.
• In some jurisdictions, regardless of bet size, there is an award cap on any single transaction. See the paytable for details. A transaction includes the results of the bonus, plus the outcome which launched the bonus. If the award cap is reached in the bonus, the bonus ends immediately, even if there are remaining free spins.

RTP=96.24%.

Additional Information

Expected Payback

• In accordance with fair gaming practices required in most legal jurisdictions worldwide, each and every game outcome is completely independent, except in cases where one spin unlocks a feature for a subsequent spin or series of spins, per the game rules. The odds of getting any particular outcome are always the same.
• The odds do not vary based on prior outcomes, bet size, balance size, time of day, day of week, etc. For example, if the top award is won on a given play of the game, the chances of winning the top award on the next play are exactly the same. Likewise, prior losses do not change future odds.
• The expected payback reflects the theoretical return across a very large number of plays by numerous players over an extended period of time. The results for any given player over a play session can vary widely from this long-term, expected average in either direction. The fewer the number of games played, the wider the normal variance of actual payback that may be experienced.
