Bricks

Bricks are a currency originating in Scrap Clicker 2 and were later introduced in ScrapTD. In Scrap Clicker 2 they are used to buy some upgrades while in ScrapTD they are used for buying and upgrading barrels and defenses.

In Scrap Clicker 2
Unlocked at x15 Stars, Bricks are passively accumulated. The growth of this is exponential.

Initially, you get 1 brick per second, but the production can be increased in the following ways with all multipliers stacking:
 * Permanant
 * Upgrading overall Star multiplier: x4 multiplier.
 * Spending levels: multiplier initially.
 * The level requirement increases by 1 every time you do this, starting from 2.
 * There are tree upgrades that improves this by reducing the requirements and improving the multiplier.
 * Upgrading "More Bricks" upgrade by spending Bricks: x1.25 multiplier.
 * (x40+ Stars) Purchasing specific upgrades in the Skill Tree: multiplier or more, depending on the description.
 * (x115+ Stars) Upgrading the scrapyard v4: x1.5 multiplier/level.
 * Temporary
 * Obtaining Brick Multipliers.
 * Activating Ad event "x100 Bricks", which lasts for a minute.
 * Considering that you can usually get a x100 mult quite easily, this ad event is not that useful, unless you are going for ad counts.





Upgrades
"More Steel Beams" is unlockable at x85 Stars through the Skill Tree. It has its cost multiplied by 8 each level, while the others have them x4 per level.

* The max level is stated to be 100 initially, but most of them has their limits changed as soon as you purchase their 100th upgrade. The only upgrade that doesn't is "More Scrap", requiring a Skill Tree Upgrade to increase it.

Brick Multipliers
Once the player has achieved the top Golden Scrap Multiplier at Barrel #97, they can begin earning Brick Multipliers, which multiplies their brick production.


 * It starts with x4 at Barrel #103.
 * It is improved by roughly 8x every 6 barrels for 18 times, until x64Q at Barrel #211 ;
 * ~16x 10 times, until x64O at #271;
 * A 31.25x to x2N, a 128x to 256N, two 125x to x32D & x4UD, a 250x to x1DD at #277; 283; 289, 295; 301 respectively
 * And a 1000x improvement every 6 barrels afterwards, maxing out at x1Squ at #565 as of update 10.8.

In ScrapTD
Bricks can be used in ScrapTD to unlock Defenses and Barrels and level them up. They are awarded after every match if the player has energy left.

Arena Brick Multipliers
You can get more Bricks after every Match by getting into a higher Arena. Apart from having more Scrap in a Match, this is currently the only way to get more Bricks. Ziegelsteine
