Blockbuilding is a technique for intuitive solving by creating groups of blocks and joining them together. It is used in the sub-steps of many methods including: Petrus, Heise, Roux and ZZ. Blockbuilding is an alternative to using algorithms, but it can take longer to execute due to its intuitive nature.

Block Building Big Cubes Edit

Most people use the reduction method to speedsolve the 5x5x5 cube, but a few use direct solving to complete the puzzle. While doing that, there are some situations that do not occur on the 4x4x4 cube (or any even cube).
