IOS Game prototype - Draw lines on a piece of paper

I would like to build a game prototype, where user draws lines on A4-paperlike view. For the the game prototype I have three main requirements. (Note! see attached picture)

1) Programatically create a square-paper like view, to which user can draw lines.

2) Lines can only be drawn through crossing of the squares.

3) Lines need to be drawn horizontally, vertically or diagonal.

You need to be able to do following:


Programatically generate A4-squarepaper-like view.

View must have varying gridsize, minimum 100 x 100 squares.

Grid-view needs to be zoomable.


Lenght of the line is fixed to 5 squares.

New line need to cross existing lines.

Draw line by point using finger at starting point and dragging to


Lines are not allowed to overlap each other, only cross each other.

Undo line functionality/button


Keep count of number of lines

Track time

Before bidding see attached picture(, which shows prototype on real paper).

For the prototype I am not willing to pay more than 50EUR (non-negotiable). I will prioritize those bidders who are able to give me estimate how fast you are able to produce working prototype.
