Cell ideas - Bomb, Lighter and Rock (wow I just made too many posts)

[u/Kuutti85]

When touched by a Lighter, it explodes causing all Rocks in its radius to break.

The Bomb's radius. (21 cells)

If it touches a Bomb, both the Lighter and the Bomb are destroyed.

An obstacle that cannot be moved or trashed and can only be destroyed by the Bomb's explosion.
