*Bangs head on desk
Damnit forgot my DS today. I bought drill spirits yesterday, and while it rocks (NZ,AU,Euro version with Dristone mode) I kept thinking Just ONE more puzzle.
Polarium is good. I need to get all these puzzles on my DS now! If they make a sequel that flashes it up a bit, maybe add a gameplay element and gives it online so we can share puzzles without typing in a code, or download new puzzles from Nintendo I'd be first in line.
mrkgoo, you keep mentioning a couple of simple rules that make them a lot easier, care to explain them here (if you can, I mean if it's something you just click on to then I follow I think) I'm pretty decent and the puzzles, but can't just look at one and use a simple concept to solve all. I also couldn't tell that that unsolvable one was unsolvable.
Well, perhaps I'm exaggerating abit...the rules aren't universal, and fairly basic, but helps to not get into an impossible solution. It depends heavily on each puzzle, and many are obvious, but basically:
* since horizontal lines are the key, a white and black beside one another measn that a line cannot go across them. Try looking for approaching either of those blocks from above and below.
* look for 'dead ends' - solitary or isolated blocks within a row, that if you change, it means you cannot continue anyfurther - consider these to be possible start points.
*if you can possibly complete lines without using your only two 'ends', then you're doing well. (find a way in, do what you need, and back out again).
* try not to get in the mode of looking at black and white, but just different. This helps with the inverting every few attempts. That is, try to think instead of saying, I need this line to be black, saying, I need this line to be the colour of these three blocks. This will enhance you ability to 'see' the path required.
*Open areas of black with isolated white blocks have two approaches - either get to those white blocks without touching the rest, or turn the rest of the blocks white, avoiding those isoalted blocks. Keep in mind that just because one line needs to be balck, the one above it isn't necessary. Yeah, it sounds obvious, but that's what I mean by the strategies are dependent on the puzzle. Like you can see that if you turned this square white, it means you HAVE to draw yourpath in a particular way, ending in an impossible way to reach another area.
*try to attempt a few lines (like the top opr bottom four) and see if you can complete them with your ends free (so they can access the other four).
*learn what is possible witht he movement of your stroke - like trying to complete a 2x6 area, where you can enter, and the possibilities of where ti can exit. Learn what is possible at the edges
* look for things like, can an area in the middle be completed with out using the edges?
Yeah, they're all just common sense, but maybe I just get a reasonably good feel for things -it;'s mostly sub concious, so it's difficult to explain my thought patterns. I figured the impossible puzzle was impossible becasue the board was so small. The two rows on the 2nd and 4th line need to be cleared by 1 of 3ways (assuming the patter for these lines is BWWWB):
2nd line: WWWWW
4th line: WWWWW
2:WWWWW (the opposite way is the same situation)
4:BBBBBB
2:BBBBB
4:BBBBB
Now if the first case were true, and the solution meant lines 2 and 4 were white, you somehow have to make the centre row black or white. Totally white is impossible, since the centre row is WBWBW - you can't reach the black blocks if the row above and below the centre line are to be white. Similarly, the centre line can never be totally black, since the centre W block cannot be reached.
Now if the second case is tru, and the second line is black, and the 4th is white for the solution, then you have to get to the centre line somehow again. One of the two patterns must be reached (Xis where your stroke needs to be):
OOOOO
OXXXO
OOXOO
OOOOO
OOOOO
OOOOO
OXXXO
OXOXO
OOOOO
OOOOO
For either case, your stroke needs to approach it form the top (if you are to make the 4th line white), and if you try, it cannot be done, or it requires theuse of both your 'ends', meaning you can use them on the bottom row (which you'll need if the 4th line is to be white)
Now, if the solution was the third condition, it means the middle three of lines 2 and 4 must be turned black. NOw consider the centre row again WBWBW. The two side W's need to be turned black, and since they can't be approached from above or below to achieve the line 2/4 completely black solution, that means they must be the 'ends' to your stroke. For them to be ends, makes it impossible to finally get that centre block black, without using another 'end' that is, try to make either of these patterns (follow the X's)without using the ends of your stroke (E refers to the supposed postions of teh ends of your stroke):
OXOXO
OXXXO
EOXOE
OXXXO
OXOXO
OOXOO
OXXXO
EOXOE
OXXXO
OOXOO
That is, your ends are used, and it makes it impoassible to reach the centre block with out using another end.
SO, for both lines 2 and 4 to be black in the solution, the centre line must be white, right? wEll, to make that happen, you need to atleast do either of these in one stroke:
OXOXO
OXXXO
OXOXO
OXXXO
OXOXO
or
XOXOX
OXXXO
OXOXO
OXXXO
XOXOX
Neither which is possible, without using more 'ends'.
Ok, now Icould really be made a fool, if there was a solution to that puzzle. But basically, you get the idea of how I go about solving the puzzles. Obviously, the larger puzzles are harder to follow, but you normally break down regions into what can and can't be done to follow the rules:
A black block next to a white meand either has to be changed, but not both, and they can only be approached from above/below or the opposite side...not through both, AND you only have two 'ends' - if using a particular place uses an end, and it creates two more 'ends'...= impossible stroke.
anyone do my puzzle? I tried to incorporate all the things I found tough in a puzzle. There's possibly a lot of solutions - meaning the parts of the puzzle can be apporoached many ways, making for an easy puzzle, or the opposite, where only one path can obviously be taken, which also means easy.
