Spinjitzu Smash DX Spinjitzu Smash DX is an online game on the Ninjago website , and is a sequel to the game Spinjitzu Smash ! . Gameplay . The player first chooses a character ( either Cole , Jay , Kai , or Zane ) . Each ninja starts off with different stat levels for each element : earth , ice , fire , and lightning . These , along with health players start with at the beginning of each level , can be increased when they earn enough experience points , allowing them to level up . The stat levels can also be raised in different ways by choosing different weapons , though these changes only last as long as that particular weapon is in use . Unlike in Spinjitzu Smash ! , where each ninja had his own story to complete , there is only one story for all of the ninja , which parallels the story in . In the game , Kai ' s sister , Nya , is kidnapped , and the ninja must find the dragons they had previously fought with in order to journey to the underworld to save her . There is also no training level . The level structure and gameplay in the game are almost identical to the level structure and gameplay in Spinjitzu Smash ! . Both the ninja and enemies each have nine square tiles , organized in a square , which they can move between . These two squares are side by side , but the player cannot cross over to the enemies ' side , just as the enemies cannot cross over to the player ' s side . The player uses the arrow keys or the " W " , " A " , " S " , " D " keys to move . The spacebar is used to shoot kunai at enemies , and deliver a certain amount of damage based on what level the player is at . The player can also use cards by pressing the " 1 " , " 2 " , " 3 " , " 4 " keys . The cards provide different power - ups , such as increasing the player ' s health or allowing the player to deliver greater damage to enemies . These cards are continually replaced with new ones . A bar on the bottom of the left of the screen starts loading after players receive a new set of cards , and once it is finished loading , players are given a new set if they have used up all of their cards or if they press the " E " key . Once the enemies onscreen are defeated , new ones take their place . All enemies must be defeated in order to complete the level . At the end of each level , the experience points and coins earned by the player in that level are tallied up . Also like in Spinjitzu Smash ! , players may check their stats ; use the coins gained to purchase new , unlocked weapons or cards ; or enter secret codes in between levels . They may also choose to play another level that is either related to their quest ( " Story " ) or is not ( " Random " ) . There is a certain number of each card that the player can buy , which allows them to use it more often in their decks in comparison to other cards . To make their own decks , players must choose one of the weapons they have bought that they will use the deck with . Any bought card can be used if the player ' s stat levels with the chosen weapon meet the card ' s requirements . A total of 15 cards may be added to a deck , but since cards are continually replenished in the levels , this only represents which cards will be used in the levels and how often they will appear .
