With this strategy I got 2250 points in code breakers before not being able to stand it anymore, but maybe you have the time to get a high score, so here it goes
1st move : do two reds and two whites, like this RRWW
If you no colors match then you just saved yourself a move over the 5 move try all solid colors way of playing
2nd move if there is a match : go all white or red, WWWW. Now this also has an advantage over the solid colors for 5 moves since your first move had two white on the right hand side if it comes up that you have a correct color, but in the wrong position your first move, and then your second move that is all white tells you that you have a correct color in the correct position, then you just narrowed that white stone down to two left hand slots. If your second all white move tells you that you have no matches, and the first move says that you have one or two but in the wrong position then you know you have the corresponding number of reds where the whites had been sitting.
Move three : orange and yellow OOYY, next your going to repeat steps one and two with orange and yellow
Move four if one matches : OOOO same as step two
Move Five : this is where your going to mix things up by now you either have one, two, or three matches from the colors Red white orange and yellow, and have two left so by process of elimination you can place 4 purple stones PPPP, and deduce by the number of matches you have so far and by the number of matches that are purple , how many greens are left.
Special case: The one area that almost got me is that on later levels they will re-throw a 1-3 combo (like white red red red) at you, and this is how I incorrectly approached it
first move : red red white white – no matches
2nd move : orange orange yellow yellow – one correct, one out of place
3rd move : orange orange orange orange – no matches
4th : purple purple purple purple – one match
Right now I was assuming that I had two yellows, one purple, and one green – (was three yellows and a purple) but watch out make sure you look to see if your matching and out of place are = 4 bars, if it doesn’t after the first move at aligning them then go back to the space you had two at and try the other color too see if there are three of it. – Jh
