Ball Tower Defense has a variety of crates that you can unlock to summon units. One of the crates is known as Rock Crates but you can't simply obtain them by speaking with the Crate Shop NPC. So here's a quick guide to help you get Rock Crates in Roblox Ball Tower Defense.

How to earn Rock Crates in Roblox Ball Tower Defense

There are two ways to obtain Rock Crates in Roblox Ball Tower Defense. The primary way is by completing the Mountains map where the Rock Crate may be given as a part of the rewards. However, this item isn’t guaranteed. Similar to units, there’s only a certain chance of receiving this crate as a reward. Here’s a look at the drop rates:

Map	Difficulty	Drop Rate
Mountains	Easy Mode	1/16
Mountains	Medium Mode	1/8
Mountains	Hard Mode	1/4
Mountains	Expert Mode	1/2
Mountains	Boss Rush Mode	1/2

Alternatively, the guaranteed way to get Rock Crates in Ball Tower Defense is through trading. You can join the game's official Discord server and look for players who are ready to trade their Rock Crates in exchange for other items. You can also use the in-game chat feature but I recommend joining the Discord server to find a ton of trade options and secure a fair deal.

Usually, other players want gems in exchange for Rock Crates as this is the game's main currency. So make sure to save plenty of gems if you want to opt for the trading route.
