1. Upgrade method
Only the sandbox brought by the player can be upgraded. The exclusive sandbox for the plot and certain levels cannot be upgraded.
Players can use sandbox cores and building blocks to upgrade. Each sandbox upgrade will unlock a new number of grids and increase the basic number of steps.
Sandbox cores can be obtained through the plot, in the diamond store in the mall, or in exclusive paid gift packages.
Building blocks can be obtained after passing the plot, and existing building blocks can be synthesized into new building blocks of random shapes.
2. Sand table function
In "Adventure", the larger the free sandbox, the more steps you eliminate, and the stronger the combat power you gain. You can take more adventures, get more rewards, and increase idle output.
When the combat power is not enough, you can continue the adventure by upgrading the sandbox and re-eliminating or using other methods to increase the combat power.
