Lego Harry Potter's gameplay is similar to that of most previous Lego video games, with an emphasis on collecting, exploring, and solving puzzles. Casting spells is an integral part of the gameplay, with a wide range of spells available for unlocking as the player progresses. As there are many spells available in the game, the player can use the spell wheel to select the spell. Potion-making is another integral feature. (wikipedia.org)
