Big Adventure: London Classic is a casual adventure game that combines hidden-object scenes with a variety of puzzles and mini games. You will follow a family of tourists as they travel around one of the most exciting cities in the world. Along 51 destinations, you will be visiting places such as the House of Parliament and Scotland Yard, in order to collect objects and solve puzzles, while you also learn interesting facts about London landmarks.
The game consists mainly of hidden-object scenes where you need to find the items that appear on the list. These objects are not actually connected to the adventure or the scene you are exploring; they are just random items of any size that are scattered around and well blended with the environment. Hints are available in the form of golden coins that you need to collect from HO scenes. Besides revealing an object's location, hints can give you additional points for your score, extra time to complete the round, in case you're playing the timed mode, and can also be used to skip mini games. Objects are really easy to find in the first rounds, so you may not even need to use the clues at all; they are cumulative and you can save them for higher levels.
After a hidden-object puzzle, the game will present you with a mini game that you can play to rise your score or simply skip as long as you have "skip coins". These games include match-3 puzzles, jigsaws, mahjong, puzzles where you need to connect wires, and a nice variety of inventive games, most of them well thought out and worthwhile playing.
As far as graphics go, the game looks stunning, with very detailed locales that illustrate the city in a very attractive way. There is a nice piano tune playing along as you explore the city, which goes very well with the game atmosphere and relaxing mood. In a nutshell, it is a beautiful, soothing hidden-object adventure that offers plenty of destinations to explore and lots of clever mini games to solve.
