Book of Ra is a Greentube video slot released on 3 March 2005 with an Ancient Egypt setting, five reels and a free-games feature built around its Book symbol. The classic specification for the 94.26% RTP variant uses 9 selectable paylines across a 5x3 layout. Its defining sequence begins when scattered Books open a round of 10 free games, during which one regular icon becomes a special expanding symbol.
Book of Ra places Egyptian artefacts, card ranks and an explorer across five reels. Winning line combinations run from the leftmost reel towards the right on the selected paylines, while the Book has separate wild and scatter functions.
Book of Ra keeps its feature set focused on the Book trigger and the symbol selected before the free games begin. The outcome of each paid or free game is random, so selecting more lines changes the combinations covered by a wager but does not make the bonus round due.
Book of Ra has the following verified specifications:
Book of Ra is listed by Wildz with 94.26% RTP, volatility of 7/10 and demo access. The game’s information panel remains the relevant place to confirm the active line selection, stake and rules before starting, because technical configurations can vary between markets and releases.
Book of Ra produces standard wins when matching symbols land on an active payline from left to right without a gap. Players choose the available lines and stake before starting a game, and line awards are multiplied by the amount bet on that line.
Book of Ra also evaluates scattered Book symbols independently of the selected lines. Scatter awards are based on the total bet and are added to qualifying line awards, but neither a previous loss nor a previous feature changes the random result of the next game.
Book of Ra uses the Book as a wild symbol in the regular game. It can replace the other standard symbols when that substitution completes a paying line, while the same icon also acts as the scatter that opens the free-games feature.
Book of Ra awards 2x, 20x or 200x the total bet when 3, 4 or 5 Books appear as scatters. These figures describe the game’s programmed paytable and do not mean that a Book or a bonus can be produced by increasing the stake after an unsuccessful game.
Book of Ra selects one regular symbol as the bonus symbol when the free-games round begins. If that chosen icon forms the required result during a free game, it expands to occupy all three visible positions on its reel and pays across the selected lines.
Book of Ra keeps the selected symbol for the free-games sequence, including any retriggered games. The selection is controlled by the game rather than the player, and no line choice or betting pattern can guarantee which icon will be chosen or whether it will expand.
Book of Ra awards 10 free games when 3, 4 or 5 scattered Books land. The free games continue with the same stake and selected paylines as the triggering game, and another qualifying Book combination can add 10 more free games.
Book of Ra applies its special expanding symbol throughout this round, creating the feature’s main difference from the base game. A retrigger extends the round but does not alter the independence of each result or ensure that the selected symbol will land in a paying position.
Book of Ra has an RTP of 94.26% in the MGA configuration listed by Wildz. RTP is a long-run mathematical percentage calculated across a very large number of games, not a promise that a single session will return that proportion of its stakes.
Book of Ra may exist in other mathematical variants, which is why the value shown inside the game should be checked before real-money play. Short sessions can finish above or below the theoretical percentage, and previous results do not move the next game closer to a win.
Book of Ra carries a Wildz volatility rating of 7/10. This indicates a higher-volatility profile in which the balance can move unevenly and the expanding-symbol free games account for an important part of the game’s potential outcomes.
Book of Ra volatility describes the distribution of results rather than their order. It cannot predict when a feature or line award will appear, so stake size should be chosen with the possibility of extended periods without a substantial return in mind.
Book of Ra lists a standard top prize of 5,000x the line bet in its classic specification. The same specification gives a free-game top prize of 45,000x the line bet per free game, reflecting the effect of an expanding symbol across the selected paylines.
Book of Ra expresses these limits in relation to the line stake, not as a guaranteed multiple of the total bet. The displayed paytable and win-limit information in the live game should therefore be read before wagering, particularly where the selected number of lines affects the total stake.
Book of Ra starts with a choice of available paylines and a stake within the limits displayed by the casino. After confirming the total cost, start the game and read wins from the leftmost reel across active lines; 3 or more scattered Books are evaluated separately for the feature.
Book of Ra real-money play in Great Britain must be supplied by an appropriately licensed operator. Statutory online slot limits cap each game cycle at £2 for people aged 18 to 24 and £5 for people aged 25 or over, regardless of a game’s own wider technical stake range.
Yes, Book of Ra can be played on compatible mobile phones and tablets. The online version supports mobile and desktop formats, with the five reels, line selection and Book feature presented through a browser-sized interface.
Book of Ra mobile play uses the same underlying random mechanics as desktop play. Screen size does not change the RTP, volatility or feature probability, and the operator’s age checks, stake controls and account limits still apply.
Yes, Book of Ra has demo play available in the Wildz configuration. The free version uses virtual credits, allowing the line system, Book trigger and expanding-symbol round to be viewed without staking or winning real money.
Book of Ra demo results do not predict real-money outcomes, because each game remains random. At British licensed gambling sites, access to free-to-play versions of gambling games is also subject to age-verification requirements.
Book of Ra may be supplied in Great Britain by an online casino with the appropriate Gambling Commission permission and access to the Greentube game. Customers must be 18 or older, complete the required verification and follow the operator’s safer-gambling controls.
Book of Ra is listed in Wildz’s international catalogue, while Wildz states that visitors from the United Kingdom are redirected to partner casinos. Players should check the Gambling Commission public register for the business that ultimately provides the game rather than assuming the international catalogue itself confirms British availability.
