Discover awesome game features, including Free Spins and Rolling Reels, during a game of the online slot Big Boom Riches. 

    Big Boom Riches Game Overview

    The bet sizes available in Big Boom Riches range from 20p to £25.  

    Betting in this game is fixed at 20 paylines. 

    Wild Symbols

    There are three types of Wild symbols in this game: 

    • Regular Wilds
    • TNT Wilds - can appear in the base game only
    • X Wilds - can appear in Free Spins only

    All Wilds substitute for every other symbol except Scatters. 

    Three or more TNT Wilds landing in the base game will award you a cash prize. 

    Cash prizes can only be won in the base game. 

    Whenever a Wild substitution occurs, only the highest possible winning combination on a line, according the the paytable, will payout. 

    Rolling Reels Feature

    Rolling Reels can trigger in the base game and Free Spins, after any win.

    It sees all winning symbols removed from the reels.

    Symbols above will then fall into the new empty positions.

    This feature also triggers if a TNT Wild or X Wild appears. 

    In this case, the TNT or X Wild will be removed from the reels, as well as all adjacent symbols - Scatters and regular Wilds will not be removed though.

    Rolling Reels ends when no new wins are secured, or there are no TNT or X Wilds in view.

    Scatter Pay

    Three, four or five Scatter symbols on the reels constitutes a Scatter win.

    The Scatter payout is awarded as a multiple of the total bet, according to the paytable.

    Scatter wins are added to line wins.

    Big Boom Riches Free Spins

    Land at least three Scatters in the base game to trigger this feature and receive nine initial free spins. 

    Triggering Scatters will pay out before Free Spins begins. 

    Every Scatter that lands in the round will award one extra free spin.

    Scatters that appear in Free Spins do not pay. 

    A multiplier is in-play during this feature - it starts at x1 and increases by one each time an X Wild appears. 

    Free Spins wins are automatically collected; individual wins will be multiplied by the current multiplier.

    Free Spins uses the same bet as the triggering spin.

    Return to Player 

    Return to Player (RTP): 96.06%.

    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 £96.06 of wins.
