The game follows the film nearly word for word but misses out on some points from the book, just like the film did. There is also Quidditch & 2-player Duelling. Combat spells currently implemented include a shield spell (" Protego") cast by crossing the Wii Remote and Nunchuk, a standard attack spell by striking downwards with the Wii Remote (" Stupefy"), a charged version by holding the Wii Remote up for longer first, and a more powerful attack spell by swinging the Wii Remote and Nunchuck to the left. Moving in order to dodge is done with the Nunchuk Control Stick, while casting spells is done with Wii Remote and Nunchuk gestures. Harry Potter can duel against Draco Malfoy in a Duelling Room with a long platform, similar to the one seen in the second film, but wider to allow dodging of spells. If it starts vibrating, that is the sign to move away before it blows up. Another possible step is stirring the mixture with the Wii Remote until it changes colour. The steps include picking up vials of liquid, shaking them (by shaking the Wii Remote) until they froth, and tipping the Wii Remote to pour it into the mixture, being very careful not to pour in too much. Potion brewing involves following a complex recipe one step at a time. But unlike the previous game, players can now also use the motion sensing and vibration features to brew potions. The game utilises the Wii Remote features as it did in the Harry Potter and the Order of the Phoenix video game.

In Harry Potter and the Half-Blood Prince, Dumbledore prepares Harry for the final battle that he knows is fast approaching as Voldemort is tightening his grip on both the Muggle and wizarding worlds.
