Solved: Hard Level 1

Recently we got the following review in the play store:

Good until! Really enjoyed the game while you could play with logic. Started to loose interest when guessing became what seemed to be the only option. At level Hard (2 star).

As a reply I posted the following:

Hi David, all levels can be solved by logical deduction, but some strategies are quite complicated. At which point did you start guessing?

To demonstrate that even the hard levels are solvable by logical deduction I’ll give you a quick “walkthrough” of the first level in the hard bundle:

Some fields besides a 2×4 area can be excluded.

The columns 0 – 1 of the board contain 2 areas that can only have stars in that column, thus all area points from other areas in that column can be excluded

Shape column (2) has 2 groups with empty fields left, both must – based on their size – have 1 star, one is small enough to directly place a point

If a field is adjacent to all other fields in its island, we can exclude it.

The marked fields are neighbours of a group in area 3 that definitely contains a star an can therefore be excluded.

The marked fields are neighbours of a group in area 9 that definitely contains a star an can therefore be excluded.

The island 6 is shaped in a way, that all stars must be in column 9. Thus all other fields in column 9 can be marked as excluded.

  1. To Paragraph Eins,
    I like to work through puzzles learning the thought processes by myself if possible.
    Like playing golf (on grass, with clubs and a ball). Learn first how you will naturally play with your own strengths and weaknesses, then get someone else to look, coach and then fine tune your strengths (professional lesson).
    It was interesting to see some of the different ways that you showed for the thought process to work the puzzle.
    My only disappointment with Starbattle is that I must invite friends to open some levels. I play games solo and refuse to connect to anything except family with social media.
    Other than my one complaint, Starbattle is a great game to sit and peacefully work through.
    Thank you greatly for your assistance.

    1. Thanks for your feedback. So I guess you would be interested in further posts about advanced strategies to solve difficult levels? Concerning the invite only levels: we heard that complain from several players and will offer an alternative in one of the next updates. Be patient 🙂

  2. I’m confused by the third diagram on this page. The accompanying text says:
    “The columns 0 – 1 of the board contain 2 areas that can only have stars in that column, thus all area points from other areas in that column can be excluded”

    The column numbers start at 1, so I’m guessing this means “The columns 1-2 of the board contain 2 areas….”?
