Well done to Ci Hui Minh Ngoc from Kelvin Grove State College Brisbane in Australia sent in some comments and strategies for this game:

__1 ^{st} Move Advantage:__ Yes, it has the advantage as 1

__Strategy:__

I use the properties of Rhombus:

4 sides equal parallelogram. Square is a special Rhombus with angles are 90 degree.

These are additional constraints on parallelogram. That means I must check where the new points are going to place must result “equal length of 4 sides”.

I use the strategy used in creating square, in Square It.

The diagonals of the Rhombus are perpendicular to each other, so strategically, I locate points symmetry around two perpendicular lines (visualise) to maximise the chance to create a Rhombus.

Here are pictures I took after games with computer.
