Mystery Box

There are 3 types:

Basic Mystery box
Middle Mystery Box
Gold Mystery box

Basic Mystery box drops out if a player enters the game 5 days in a row. The gap between the entrances to the game should be from 24 to 48 hours. If more than 48 hours have passed since the last entry into the game, the time until the Basic chest falls out starts from zero.
Most often, Experience falls in it, less often limits on the purchase of hexagons and on the purchase of hexagons put up for sale
The number of dropped limits or inventory in the chest is from 1 to 3.

Experience can also occur in the Middle Mystery Box, and limits for hexagons, in addition to them, paint, electrical cables, and resources can also drop out. The number of these elements in the chest varies from 3 to 10. Much less often Рfarms, power plants or other types of buildings can be dropped out.

In the Gold Mystery box, the same elements as in the Middle Mystery Box can drop out, only their number in the chest is greater. After the player picked up the chest, if there is a free slot in the inventory, the chest falls into the inventory. After opening the chest in the inventory, it appears in a specially designated place on the screen (Chest open slots).
After opening the chest, its contents are automatically transferred to the places assigned to it – limits, inventory, paint.
