How do you kill Voldemort in Harry Potter OOTP for Wii? Is there a special trick or sequence of spells to cast

Just use all the spells that you've learnt to defeat him. I use the protective spell a lot (I think you flick upwards?) so prevent voldemort's spell from hitting me. Its called protego. I found petrificus totallus (clockwise), stupefy (thrust forward), expelliarmus and rictumsempra.
