Normal sudoku rules apply.

There are three different types of thermometers in the grid: slow, normal and fast. When moving along a thermometer away from its bulb, the following rules are applied:

-slow: the digits must increase or stay the same

-normal: the digits must increase

-fast: the digits must increase, the difference of adjacent digits being at least 2.

There are:

-4 slow thermometers

-2 normal thermometers

-6 fast thermometers

Two thermometers sharing the same bulb may still be of different types.

The white circle not connected to any line stands for an odd digit.

For clarification, all thermometers are straight.
