The dragon is the wild symbol. It can substitute for all the symbols, except the scatter and the bonus, and is the game's most valuable symbol.
The scatter symbol is a city floating in the sky and it offers scatter payouts of up to 666x the total bet for the spin.
The slot has a special dragon's egg ‘Split' symbol and if this lands on the fifth reel at the same time as a winning combination it will split the final symbol in that combination into two to make it more valuable. As a result, it is possible to form six symbol combinations.
If you land three or more scatters then the free spins begin. You will receive 15 free spins with a changing multiplier. You start with a multiplier of between 2x and 5x and with each winning spin it increases by 1x up to a maximum of 5x. However, each time you fail to land a win it decreases by 1x. Furthermore, during the free spins not only does the scatter act as an extra wild symbol, but it is also possible to retrigger the spins infinitely.
Dragon Kingdom offers a top payout of 25,000x if you can land six wilds across a payline. The male character can payout up to 4,000x, the female character can payout up to 3,000x, the other three high value symbols can all payout up to 2,500x.
