Luxor HD is an excellent marble-popper for iOS. I have played it on the iPad for months. However, I took a two-month hiatus. But now, I am back on this game. Gameplay - 9.5/10 It plays out very, very well. To play, players must match three or more spheres by launching colored spheres to destroy them and prevent them from entering the yellow, green-capped pyramid at the end of the path. Players can also practice very difficult maps in Practice Mode, set out to defeat the antagonist of the game, Set, in Adventure Mode, or try to see how long they can last on a selected map in Survival Mode. Also, they can receive special "Achievements" after fulfilling certain deeds, such as completing a level without losing a life. Sounds - 9/10 The games sounds and music tracks are really great for a casual game. I like how when the spheres roll out onto the path at the beginning of a level, they sound like real spheres made out of marble. The music tracks really give the game more of an Egyptian-like feel. However, if players do not like the in-game music, they can always play music from their iTunes library. Graphics - 10/10 Luxor HD has amazing, shiny graphics. The maps look much more life-like, with paths made out of glass (or any other material), reflections of spheres and scarabs on the ground, shadows of palm trees, sparkling gemstones, etc. I love how many colored sparks bolt out in random directions immediately after destruction of spheres. Fire a lightning ball at a vertical section of the path that is full of randomly colored spheres, and the effects will be much better! Plus, when spheres explode, I like their fountain-like star effects. That adds to the special effects of destroying spheres with a lightning ball. Overall Rating - 9.5/10 ≈ 5/5 Luxor HD is a must-have for people, casual gamers and non-gamers alike. It will keep you playing for hours on end, until you either lose all of your lives, or you beat the final level. One last note: Never ever give this app (and any other apps) a 1-star/2-star rating just because it crashes.
