programming DE1 kit using Quartus 2

thanks a lot for your advice.....I finally got my DE1 running!!!.......the problem was with the driver.......Its really exciting working with DE1 board....I started running some simple digital circuits like muxs,decoders,encoders........I did run across a problem with the pin assignment....when I assigned for toggle switch 10 and the ninth one is working instead:confused:....i did recheck with the datasheet.....Is it normal for the De1 board to give such kinds of incorrect assignments......I would like to push the functionality of the kit further and I came across videos of implementation of games like mario in the DE1 board ...can u tell me how i should go about coding it.....
