    Book of 99 Game Overview 

    The bet sizes available in Book of 99 range from 10p to £50.

    Betting in this game is fixed at 10 paylines.



    In this game there is a collection meter exists, which starts at 0 and can increase to 99.

    For each Wild symbol that is displayed in the main game, it will increase the collection meter by 1.

    It is possible to trigger Free Spins in one of two ways; you can land at least three Wild symbols anywhere during a spin, or you can accumulate enough Wild symbols to complete the collection.

    If you unlock Free Spins via collection, the bet size used is the weighted average of the bet sizes used when collecting each Wild. 

    If you trigger Free Spins by landing a minimum of three Wild symbols, you will play your free spins with an identical bet size to the one used on the triggering spin.

    The average bet size must be an integer multiple of the minimum bet. If this is not the case, it is rounded according to the rules of stochastic rounding (e.g. if the average becomes 1.2 times the minimum bet, with a 20% probability it will be rounded to 2x the minimum bet and with 80% probability it will be rounded to 1 times the minimum bet).

    Once you have collected 99 Wild symbols and you've triggered the Free Spins bonus, the value of the collection meter is reset to 0.

    Should you collect a greater number of Wilds than 99, and you have triggered Free Spins, the collection meter will be reset to include the remaining Wild symbols. For example, if you've collected 101 Wild symbols, the collection meter is reset to 2.

    If at least three Wild symbols land and you complete the collection simultaneously, you will play the Wild triggered Free Spins first, and then the collection triggered Free Spins subsequently.

    Free Spins

    You receive 10 free spins when Free Spins is initiated.

    One of the nine regular symbols is selected at random to be the special symbol for the entirety of this bonus round.

    Any normal wins are paid out first on each spin. 

    If you have enough special symbols (two for high paying symbols and three for low paying symbols), they will expand and cover the whole reel, paying out for each of 10 lines. 

    This happens irrespective of their horizontal position, according to the amount of symbols and the corresponding pay table value. 

    Any existing Wild symbols are disregarded with regards to the expanded special symbol payout.

    An extra 10 free spins are awarded when three or more Wild symbols are displayed during a free spin.

    Return to Player

    Return To Player (RTP): 99.00%.

    The expected return is the amount we pay out to players relative to the amount of wagering on the game.

    For example, if we take £100 of wagers we will, on average, pay out £99.00.
