Then, if there are enough of the special Expanding Symbols (2 for high paying symbols and 3 for low paying symbols), they expand to cover the whole reel and pay out for each of the 10 lines, regardless of their horizontal position, according to the number of symbols and the corresponding pay table value. Note that any existing Book Symbols are disregarded for the Expanding Symbol payout.
• If multiple special symbols exist, this is done sequentially for each of the special symbols.
• Landing 2 or more Book symbols in a spin awards an additional 5 spins. Every additional Book symbol that landed beyond the second awards an additional 5 spins.
• Whenever any extra spins are awarded, one of the regular symbols is chosen as an additional Expanding Symbol. If the symbol chosen is already a Expanding Symbol it is instead given a multiplier that increases by one every time the symbol is chosen. This multiplier may never go above 9. Any changes in Expanding Symbol or multipliers take effect starting in the following spin.
