Nice one you get to understand it
Figured it out, but it would have been better if the instructions were more clear. Basically, I started by typing in 4 of the same numbers. If i got a w, I know I need that letter. If not, I don't use that letter. If i get 2 w's then I use that letter 2x. Once you know the four numbers you need, experiment with different combinations and the goal is to get 4 w's to win. if you get 4 b's, then all 4 of the numbers are in the wrong spot. if you get 2 w's and 2 b's then 2 are right and 2 are wrong. If you exchange the 2 that are wrong then you will win.
Hope this review makes sense to anyone puzzled by the game and hope this doesn't get blammed just b/c people can't understand it. If so, I suggest making it again but with better instructions and a little music wouldn't hurt either. In any case, I had never played a puzzle game like this before and actually liked it.
