visual - Pixel Cipher Puzzle


You are given the following plaintext/ciphertext pairs:



image 1 they_got_my_contract_back_to_find_ to_their_alarm_a_dog_had_signed_




image 2 sonic_boom_sonic_boom_sonic_boom_ trouble_keeps_you_runnin_faster_ sonic_boom_sonic_boom_sonic_boom_ save_the_planet_from_disaster_





image 3 even_though_weve_never_said_it_ theres_something_that_ the_two_of_us_both_know_



Derive the plaintext that corresponds to the following cipher text:



image 4




Answer



The answer is




"but_the_sun_rolling_high_through_the_sapphire_sky_keeps_great_and_small_on_the_endless_round_". Each column represents a letter of the alphabet, with the final one representing underscores. The top left part of the puzzle shows the order in which coloured blocks need to be interpreted, from left to right, top to bottom. So in the final puzzle, we convert red blocks first, then blue, then green, then purple, then grey. (I'm not sure whether I'm proud or ashamed of the fact that I got the full answer after translating "but the sun rolling high")
