making a gamefield (without using a double array)

[liluma]

i'm just wondering if its possible to do that...

i know for games like snake and such you can make a gameboard by making a double array like this

Vak[][] gameboard = new Vak[lenght][width]
//and then putting the objects you want on the matching Vak

but i want to make it less blocky

so that you can simply walk around all direction and not only left, right, up and down..

can someone give me an idea how this could be possible?
