Part 1: (Comment too long) The trick on the harder levels is to pick a color, and try to find a path for it that doesn't block any other colors. For example, if you were to pick red you'd then look at all the paths it would take to connect from one stationary red block to another. After you figure out the different path options, let's say there's four for this example, look at each path and see which ones immediately block off any other color (like if red cuts in between purple with no way around, or leaves only 1 space open on the side when both orange and yellow need to pass, for example), this shouldn't take too long. After you do that, there usually is only one path left, but sometimes there are two. Regardless, map out the path (or one of the paths), and you now have a definite boundary.
Part 2: This is very helpful because the last step is to choose another color and find its paths, and a boundary will limit that number. If you had another path that wasn't eliminated from the first color, just attempt to finish until you are sure that it either blocks another color no matter what, or that it's the right one. This may seem like a pointless or simple strategy, but the thing is, when you have a finished color, the rest of the puzzle is basically mapped out for you.
On most levels, the trick to Acing is to count how many moves it takes (on the meter to the left), then subtract the number of empty slots and you'll know how many free moves you have. For example, if it takes 5 moves to Ace and there's 3 empty slots, you know that three of your moves have to be coin-to-slot moves and you have 2 free moves (of course, if you know you have to move a coin from it's slot just subtract 1 free move and add 1 coin-to-slot move).
@CAaronD the reason we all disliked it, is because the chance of getting gem notes would be way to high. Most of us kill more than 200 enemies a day. And your more recent comment has it coming every 100 enemies, and that would make buying gems, with money, completely pointless.
@echo129 but then, you could basically do that already, just put the gems on the market for a low price, then buy it with your other account. The only difference is there's a bit more of a risk that someone else will buy it.
@drdagger first off, 'fair'? the only advantage they get is they don't have to walk. plus, they paid for it so it's totally 'fair'. And please don't get upset, I'm not arguing-ish, I'm just making a point.
In the climbing minigames skip the first one, do the second one (the trick is after the first cave just keep when you pass the next caves, then when a cave gets to the bottom of the screen stop and go really fast and if an explanation mark didn't appear yet, keep going and you'll make it to at least the next cave if you don't stall), and I'd say skip the third one to, it takes to long.
For the jumping minigames, skip the first one, especially do the second one (even making it over the first very easy hole gets you two points, you can get past the seventh hole in no time at all), and the third one gets you all lot of points, but it can be very frustrating (I kind of liked it, the trick is to look at what you're supposed to do, then look at your character when you do it(as opposed to trying to look at one or the other in the corner of your eye, which is what I did at first)).
In the running minigames skip the first one and try the best on the second one.
In the swimming minigames do the first one and maybe the second one and definitely the third one.
For the flying minigames I'd say do the first one (even though it's kind of frustrating at times) skip the second one and do the third one (the first shot's easy, align the aiming arrows so it looks like it connects to the coins, for the third shot look to the first big whole in the middle mountain in the background, then set the second dot of the cannon aimer thingy a bit above the rightmost part of that first whole (of two)).
 "Cube Colossus"){kind=icon}
 "3D Logic"){kind=icon}
 "Coins"){kind=icon}
 "Straw Hat Samurai"){kind=icon}
 "Fantasy Online"){kind=icon}
 "DuckLife 4"){kind=icon}
 "Versus Umbra"){kind=icon}
 "City Siege 3: Jungle Siege"){kind=icon}
An interesting approach!
