Scrap (currency)

Scrap is the main currency of the game which you get from the barrels every second. To get more Scrap you have to merge the barrels. There are seven upgrades which can be bought in the game:

Faster Barrels (max level 40): Reduces by 0.1 seconds the barrel spawn time. A good upgrade to spend some Scrap to.

Better Barrels (max level depends in update): Makes the spawned barrels 1 tier better (for instance at level 1 you will get red barrels (Barrel 2) instead of blue (Barrel 1) ones, at level 2, orange (Barrel 3) ones instead of red, and so on). This is the most important upgrade.

More Magnets (max level 175): Gives +0.1% (or 0.5% with tree upgrade) chance to get a magnet while merging.

Double Barrel (max level 50): Gives +1% chance to get two barrels instead of one.

Better Barrels II (max level 75, or 100 with tree upgrade): Gives +1% chance of getting an even better barrel (it works like Better Barrels, but with an even better barrel (for instance if you had purple barrels (Barrel 4) you would get green barrels (Barrel 5) with a chance)).

Better Storms (max level 50): Gives an extra magnet (or one every two upgrades with Shorter Storms tree upgrade) per upgrade in storms.

Offline Production (max level 40): Gives +1% offline production (for instance if you had about 10000 Scrap per second and got this upgrade to level 2, you would get (10%+level%)=12%, which would be 1200 Scrap per second when offline.

When you get to 5 Stars, you'll be able to use it for Scrapyard too, explained in another page.
