Block fuse

A block fuse is any fuse that burns through a Blockic constellation.

This list does not include trivial fuses where a spaceship deletes or modifies stationary objects, or engineered fuses consisting of parts that can be trivially rearranged to get different speeds. Spaceship-based fuses are known for c/2 orthogonal, c/3 orthogonal, c/6 orthogonal, c/4 diagonal, and c/7 diagonal.

2c/3 bi-block fuse

Main article: bi-block fuse

This 2c/3 bi-block fuse is a clean fuse which consists of a single pre-beehive used to ignite one row of bi-blocks separated by 2-cell gaps.

p36 c/2 block fuse

This fuse can ignite two rows of blocks spaced 3 cells apart, as in a pufferfish. Despite its common speed, it has an extremely high period. It is used in pufferfish spaceship.
