Book of Ra slot machine is based on Novomatic’s game of the same name. This is 5-reel slot machine with 9 lines and free spins. It is free-spins that contain the flavor of this slot machine, because there you can win significant prizes of hundreds and thousands of initial bets per line.

Free Spins

Free Spins are the spins for which you do not have to pay credits. It is a kind of a reward for long game.

Free spins appear randomly, as well as the other combinations that bring wins. To begin the next 10 free spins, three or more Book of Ra symbols book of ra appear on the screen (on any of the fifteen visible symbols of all 5 reels). If in the case win combinations appeared on playing lines, they are paid before free spins. This win is added to total win in free spins.

The bets and the number of playing lines for free spins are the same as in the last played spin in the main game. All payouts for winning combinations per lines are summarized per 10 spins. In addition, before starting 10 free spins, a “lucky” symbol is specially assigned to the player of the symbols on the reels. "Lucky symbol" brings additional wins, as it expands to all visible reel fields vertically. In calculating winning lines formed by "Lucky symbol" the number of symbols on playing lines is taken into account regardless on their position.

Free spins are played on the reels of the same layout as in the main game, so there is the probability of additional 10 free spins, which will begin immediately after the current free spins end.

 

HOW TO PLAY BOOK OF RA SLOT MACHINE

When launching the slot machine, the player can not choose the cost of one credit. One credit may be equal to 0.01 mBTC only.
Before a new spin, you can select the number of playing lines by pressing LINE 1 ... LINE 9. Bet per playing line is cyclically changed from 1 to 25 credits by pressing BET. You can spin the reels by pressing SPIN.

Main Game

Ways of reel stopping and gambling game of BOOK OF RA slot machine are the same as the mechanisms previously detailed in Slot Machine Fair Play Control on the example of Crazy Monkey slot.

Fair Play Control in Gambling Game

Generation of the outcome of gambling game has its own specifics that we detail on the example of a separate line of the game outcome for one spin:

Spin=0,6,9,0,1 Double=0,1:1,0:1,0:1,0:0,1:0,1:0,1:0,1:1,0 SecureWord=0DcYWJHjhz85GJY9mRXVyC9guYJpyfbP

Regardless of the player’s decision to participate in gambling game or not, line of the outcome for each new spin of the reels contains data on the presence or absence of the mummy of Pharaoh in some tomb for each of possible 9 levels of gambling game (separated by a colon ":"). Part of the line Double=0,1:1,0:1,0:1,0:0,1:0,1:0,1:0,1:1,0means that on the first level, pharaoh mummy is in the right sarcophagus (0,1), on the second level, the mummy is in the left one (1,0), on the third – in the left one (1,0) (1,0), etc.
