1. Launch the game "Truck Simulator Offroad Driving" on your mobile device.

2. From the main menu, select a level to begin your transport mission.

3. After the level loads, observe the cargo loaded onto your truck and the offroad environment.

4. Use the on-screen buttons to control your truck: tap the gas pedal to move forward, the brake to slow down or stop, and directional arrows to steer left or right.

5. Drive carefully on rough terrains, including hills, mud, and narrow paths, keeping your cargo balanced and secure.

6. Avoid driving too fast or making sharp turns, as this may cause the cargo to fall or the truck to overturn.

7. Follow the designated path shown on the screen to reach the delivery point within the time limit.

8. If your cargo falls off or you fail to deliver it on time, the level will restart and you will need to try again.

9. Successfully delivering the cargo to the destination completes the level and unlocks the next challenge.

10. As you progress, levels become more difficult with trickier terrain and longer routes, requiring precise control and timing.

11. Continue improving your driving skills and complete all transport missions to become a master offroad truck driver.
