Superdozer is a game where you need to move/push all the logs to their destinations. There's no keyboard involvement in this game as all you need to do is click on the tiles to move the logs. There are multiple levels in the games and you need to complete in possible low moves to get all the three stars. Also, you need to keep track of your gaming time as well. If you spend more time and make a lot of reverts, you might end up with a single star. Once you finish a level, other levels unlocks.
All the controls are done by your mouse. You need to click on the empty tile to move your dozer. If you get any confused then there's a help button at the top of the game screen.
Picturize your moves as soon as the game starts. It helps you to not make a bad move and save you a star.
