# Dots and Crosses3

## Dots and Crosses

(OP)
Starting with a grid of dots, 5x5 like this:

Can you draw a cross that encloses 5 dots, and leaves 8 dots outside the cross?

Below is a failed example. There are five dots in the cross, but only 4 outside:

Can you draw the cross that works?

EDIT: THE ORIGINAL INTENT WAS TO CONCEAL THE ANSWER INSIDE A CLOSED "SPOILER" WINDOW.
SINCE THE WINDOW REMAINED OPEN, THE FIRST MEMBERS TO VIEW THIS PUZZLE SAW THE ANSWER RIGHT AWAY. SORRY!
I HAVE DELETED THE ANSWER, AND WILL POST THE ANSWER IN A SEPARATE POST LATER.

(OP)
Greg, have you found multiple answers? (I take it you saw my accidentally exposed answer before my edit removed it...)

STF

### RE: Dots and Crosses

There is no indication that the lines must connect to the dots in the grid...

### RE: Dots and Crosses

That was originally in the no-so-hidden spoiler box in the OP.

#### Spoiler:

The unstated non-requirement is that the drawn cross' vertices are dots. There are a number of crosses that can be drawn that are either non-symmetrical or not orthogonally drawn

### RE: Dots and Crosses

How far can we go being non-symmetrical and non-orthogonal? Could all 4 ends of the cross be different in length and width? Then it will get kinda boring

Haha!
You guys are great non-linear thinkers, even when thinking about lines. CheckerHater scores 3 points. 1 for getting the "basic" solution, and 2 for the bonus solution.
GregLocock may have come up with the same or different solutions until he posts them so we'll never know.

I was also trying some non-right-angle corners and passing out of the boundary, but I didn't get far. Now that you and IRStuff have suggested non-orthogonal lines, I got this:

### RE: Dots and Crosses

IRstuff,

I think you just added another "non-requirement": lines don't have to be straight.

How many points am I getting for this solution:

### RE: Dots and Crosses

(OP)
Okay! Okay!

My puzzle was way too easy for you guys!

STF

### RE: Dots and Crosses

my solution was a diagonal square cross ... not something drawn by a drunken fly, based on the assumption of using the points as vertices.

### RE: Dots and Crosses

(OP)
RB,
Yes, that was the "original" correct answer, that CheckerHater got on answer 5. Then all these other guys with tesseracts in their brains showed up...
