Step 1, the first stage of this puzzle is a K7 code, a K7 code cipher is a variation of A1Z26 substitution where the letter K is replaced with 7, l is replaced with 8 and so on. You can decode it with a specific K7 decoding tool or by using a A1Z26 decoder and then shifting 7 with a caesar decoder the output of both will produce the following output “S P O O K D T H H R W V O A O T T U W X”

Step 2, the next part of the puzzle is Vigenere cipher with a key of “SPOOK”, you can see the key in the output of the previous step. You can decode easily using online tools such as ones from dcode or Cryptii. After inputting the string into a decoder it will give you the final answer “LET THE GAME BEGIN”.
