The Game Principle

The goal of the Thermometer game is to set the "temperature" of certain thermometers so that the numbers in each row and column are zero.

• Each square can be part of a thermometer but must start with a round "container".
• All thermometers grow in a straight line in one direction (up, down, right, left).
• Each thermometer square placed decreases the number at the edge of the corresponding row/column.
• Empty thermometers are also allowed.
• Gaps in a thermometer are not allowed.
• Goal and End of the Game: All edge numbers must end up being zero

The Challenge

Find the correct combination of thermometers so that all conditions are met. Since there is always only one solution, logical thinking and trial and error are required.

How to Play?

To change a square, simply click or tap. The numbers at the edges change automatically. If everything is correct, all selected areas turn green.

These are environmentally friendly analog thermometers; neither mercury nor alcohol is used.
