7x7x7
The 7x7x7 is the biggest cube in official World Cube Association competitions and is a good challenge for cubers bored of the smaller cubes, even the very best speedcubers barely break 2 minutes solving the 7x7x7 but many of them still perform excellently. Solving it is very similar to other big cubes. It is also my best event since I came 2nd in the UK championship 2019 in 7x7x7.
