nestorgames currently sells only two boards for UNITY:
The Basic edition (19 euros) has 60 pieces and a size 5 hexagonal board (61 cells).
The Deluxe edition (which is only available for purchase with Bitcoin, gold, and silver; the Bitcoin price fluctuates with the value of the Bitcoin currency, but according to this converter, the current price of 25.30 BTC is worth about 240 euros) has 90 pieces and a size 6 hexagonal board (91 cells).
There's an expansion to the Basic edition (12 euros) with extra pieces, which is intended to allow you to play the Basic edition with different distributions of pieces than the default 10 asterisks and 10 rings per color. However, if you have scissors, and you are willing to spend the extra 7 euros to upgrade from just the extra pieces to an entire extra copy of the game, you can play a game with more than just 60 pieces without paying the Deluxe edition price!
Here's a look at the Basic game:
Like most nestorgames, the board is made out of rubber (like a mouse pad) to make it easy to roll up and carry without taking up much space. This also makes it easy to cut with scissors. Unfortunately, all that white stuff and those logos around the board will have to go. Trim the extra stuff of of both boards, and then cut one board like so:
(The single cell in the middle can be discarded.)
You can use the strips and the original board to recreate the Deluxe edition's board:
But wait, there's more! 91 cells can be arranged into a triangle, rather than just a hexagon, so while your neighbors with the Deluxe edition are stuck with a hexagonal shape, you can use your Basiluxe edition to play on a triangle like this:
But why play with only 90 pieces when you have 120 pieces? You can make 121-cell boards with ease, and use all of the pieces!
Your neighbors can't play with these boards. nestorgames doesn't even sell additional pieces for the Deluxe edition, so they'll have to buy another entire game to have more than 90 pieces. Sure, they have nice acrylic components, and they have slots for the walls so they lock into place instead of just sitting on the playing surface where a sneeze can move them a few cells over, but who needs that when you can have longer, more intense games, and greater possibilities for boards?
Here's the Basiluxe edition in action:
(Note: This was taken before I had the idea to cut up the 2x5 pieces to allow for the rhombus and triangle-shaped boards. I hope to try these shapes sometime.)
