Originally they were plain, wooden oak crates, which seemed to be sharper sounding when broken. These crates also were stacked neater than the later crates.
In the Ratchet & Clank Future series they changed to a darker wood with a hard plastic maroon trimming. They also sounding crisper when broken, and were easy to knock over.
Other Crates containing boltsEdit
Some of the jackpot crates contained the powerup along with about 50 other bolts. However, that did not appear in the earlier games.
In the future series, these did not only explode but also contained bolts.
Massive Crates contained a variety of items including ammo, nanotech and bolts.
