Periodic Survival is a game about using the periodic table to help you survive in the desert. But to play it, you may need some instructions.
First, you need to know what you are making. In the left section of the game there is a tablet with your instructions on it. Read the objective and pick whichever elements you need to create the compound you need.
To make compounds or select elements, you need to press the elements that make up that compound/element and then press make. If the next level button appears, you have completed the level, otherwise you will have to try again. Once the button appears click it and move on to the next level.
The Sandbox is a mode where you simply type in a compound or element and it tells you what it is. You enter your compound or element via the text box and then press make.
The elements or compounds must be entered in the right order, with the correct capitalization and the correct numbers, like so:
These are Water and salt:
Water – 2 hydrogen and 1 oxygen
Salt – 1 Sodium and 1 Chlorine
