For the primary time, a speedcuber has demonstrated an answer to the Rubik’s dice that mixes the 2 closing steps of the puzzle’s answer into one
19 August 2022
A Rubik’s dice solver has change into the primary individual to point out proof of efficiently combining the ultimate two steps of fixing the mechanical puzzle into one transfer. The feat required the memorisation of hundreds of potential sequences for the ultimate step.
Most expert speedcubers – individuals who compete to unravel Rubik’s cubes with probably the most pace and effectivity – select to unravel the ultimate layer of the dice with two separate strikes that contain 57 potential sequences for the penultimate step and 21 potential sequences for the ultimate transfer.
Combining these two separate actions right into a single transfer requires an individual to memorise 3915 potential sequences. These sequences had been beforehand recognized to be potential, however no one is reported to have efficiently achieved this so-called “Full 1 Look Final Layer” (Full 1LLL) transfer till a speedcuber going by the web username “edmarter” shared a YouTube video demonstrating that accomplishment.
Edmarter says he determined to take up the problem after seeing notable speedcubers attempt to fail. Over the course of a couple of yr, he spent 10 hours every weekend and any free time in the course of the week working towards and memorising the required sequences, he advised New Scientist. That usually concerned memorising 144 motion sequences in a single day.
All that effort paid off on 4 August 2022 when edmarter uploaded a video demonstrating the Full 1LLL over the course of 100 separate puzzle solves. He additionally posted his accomplishment to Reddit’s r/Cubers group.
His common resolve time for every Rubik’s dice over the course of that video demonstration run was 14.79 seconds. He says he had a median resolve time as little as 12.50 seconds throughout two follow runs earlier than recording the video.
The Rubik’s dice group has reacted with overwhelming enthusiasm and awe. The highest-voted touch upon his Reddit publish detailing the achievement merely reads: “That is completely insane.”
However he’s not resting on his laurels. Subsequent up, he plans to attempt working towards another strategies for ending the Rubik’s dice which have solely beforehand been mastered by a handful of individuals.
