Free Spins
Wild symbol substitutes for all symbols except the Special symbol.
When 3 or more Wild symbols land anywhere on the reels, 10 Free Spins are awarded.
At the start of Free Spins, a symbol (except Wild) is chosen to act as the Special symbol.
During Free Spins, after the payout of regular wins, the Special symbol may expand to cover all positions on the reel.
Special symbols expand only when enough symbols for a win are present.
Special symbols pay like the appropriate regular symbols but do not need to be present on adjacent positions to result in a winning combination and do not have to start on the leftmost reel.
Free Spins can be retriggered with a new Special symbol randomly selected from the remaining symbols.
Free Spins are played at the same bet as the round activating Free Spins.
During Free Spins a different set of reels is used.
Gamble
You are able to gamble any win not exceeding 75000.00 GBP.
The gamble feature is card based and you have to guess the colour of the next revealed card.
A correct guess doubles the win; a wrong guess causes you to lose your win.
The win can be gambled until a wrong guess or until a limit is reached.

You can use the HALVE option to credit half of your win to your balance and gamble the rest.
You cannot gamble during Free Spins.
