Gold boxes are a special type of drop boxes, which gives add a high amount of crystals to their collector. Gold boxes mostly contain 1,000 crystals, but while some events are held in Tanki, the gold boxes' prize is increased.
Whenever a gold box is about to be dropped, a golden text reading "Gold box will drop soon" will appear on the top of the screen for a few seconds, and a brief siren will be heard. The tile below the dropping zone will be marked with a golden image of a crystal. 20 seconds after the gold box notification, the gold box is dropped. Once collected, another golden message would read "USERNAME has taken the gold box".
As opposed to normal drop boxes, such as Double Armor, gold boxes are not dropped onto maps periodically, but are randomly dropped during the battle. Each map has its own set of drop zones for gold boxes, and whenever one is about to be dropped, one of them will be highlighted. The mechanism that drops gold boxes is triggered whenever the battle funds are increased, and drops one based on a 1/7000 probability.
It is important to note that the probability of 1/7000 doesn't mean that every 7,000 crystals a gold box would drop. A gold box can even drop with 1 crystal added to the battle, and even not drop at all in a long battle with tens of thousands of crystals in the battle funds. This proves that the chance that a gold box drops is completely random.
