Summary: I bought this game for my daughter for her birthday. The concept is great and really neat. Unfortunately, the Wii version of the game is virtually unplayable. To place the blocks you have to very precisely point and hold the Wii-mote at the spot on the screen where you need it. This makes the game hard - not hard because the puzzles are particularly hard, but hard because the player all too often misses the intended placement. It's frustrating.
Summary: I have 6-year-old twins. The principles applied in this game proved too complex for my children. I myself found the controls very sensitive and hard to master. Basically its a series of puzzles with a simple objective, push a button placed somewhere on the screen. Each level has different manipulatives to achieve the goal. You setup the objects and press the "PLAY" button. This releases a marble or a cart which starts things in motion.
Summary: My brother and I gave this to our parents for Christmas and it has been a hit with the family. My mother, who had never before played with a wii and is usually skeptical about gaming had tons of fun and even beat my father at some of the party game rounds. The standard gameplay is good for cooperative puzzle-solving too.
Summary: I wasn't a huge fan of this game. I love puzzle games on the Wii and PS3, but I thought this game was disappointing. After trying it the first couple of time, I just stopped playing it since it didn't interest me that much.
Summary: This game is very intriguing. It kind of "sucks you in". There are some things about it I wish were different. The "sandbox" phase is not explained very well in the initial instructions and seems sort of random. The puzzles are very unique and it is very satisfying when you do figure it out. Some are fairly easy to figure out and some seem almost impossible.
Summary: This is similar to a PC game called Crazy Machines that I've enjoyed. Other reviewers have noted that this may have been better as a PC game, assuming that you'd have better control with the mouse than the Wii remote, but I disagree. Control via the remote is fine, and it's a much nicer experience playing the game on the sofa in front of the big TV instead of hunched over the PC.
Summary: This game is not a time limited game, you have the luxury to take your time and think before trying; the party games do have time windows. Moving through the 100 puzzles is very straight forward, but the answers are not. What is very nice is that there can be more than one way to solve the puzzle. It takes a lot of discipline to not just hit the hint button when getting stumped, however through patience and thinking the answers can be found.
Summary: This game is fun and also strangely addictive. You are given a few beams, some balls and occasionally some strange carts, to build something which will guide a ball to hit a button. The only force you have is gravity though, so you have to really think about how to accomplish the task with the tools provided. It becomes very addictive as you work your way through the puzzles.
Summary: I thought this game was great. We compare all puzzle type games and even some others to Gravity now. Some of the puzzles are easy and some will really make you think. I would buy gravity 2 in a heartbeat. I just hope the next one is 200 levels instead of 100.
