Help with Cyclone game

how can I edit this library code for 20 LED diodes, can anyone help me? I am still new at this programming.

Instructables?

We can't see your code.

Try with this:

const int chipCount = 3;

Do you even have anything wired?

everything's wired as it should be.

Still can't see your code

#include "FastLED.h"
#define NUM_LEDS 20
#define DATA_PIN 2
#define SCORE_PIN 6
#define SCORE_LEDS 4

/*Note there are two games in this version. To toggle between games, turn on the device. Watch as the right side led strip(scoreboard)
switches from a single red led to two blue leds. Whichever mode is displaying will determain what gametype the player will play. It will switch
between game modes ever couple of seconds

GAME 1(red led on): It will prompt the user to select a color and will cycle through colors. Once the button is pressed, whatever color that
was currently on will be the next color. Afterwards, the user has to press the button when the next color appears.

Game 2(two blue leds on): The normal cyclon game. The red dot will spin and the user has to press it between the givin margins.

So, you link to some external code, ask for help, then post a totally different code?!
WTF, man?!
