Hex-tile Prototype: Impossible

For a long time I have wanted to design a game around the 3D world of M.C. Escher. My dad had a picture of the Escher waterfall hanging in his office. I was always captivated by the impossibility and reality of the image: Impossible because it could not exist in a real 3D world, Real because it DOES exist in the 2D world of the paper.
Putting 3D objects into a 2D world allows for some awesome things to happen. You are aware of this if you have played the app Monument Valley, which I recommend.
I have been working on several concepts for a 3D-2D game based on impossible geometry like that of the Escher waterfall. I have made two different prototypes. One is terrible and is really difficult to turn into a game. The other I have been able to turn into a game and I’m ready to playtest it. Today I’m covering the latter.
Impossible
Impossible is a real-time game of puzzle building and tile laying. It works similarly to Galaxy Trucker in that players will be grabbing tiles from a common pile. These tiles will then be added to their growing assembly. The objective is to create the face up Impossible Shape as quickly as possible to earn the most points for that shape.

An impossible shape in 3D, but very possible in 2D.
The game is a set number of rounds. In each round a new Impossible Shape tile is drawn. All players will be racing to complete this shape.
When someone says, “Go!,” players will begin taking tiles and building their shape. When they complete the shape they can place a meeple of their color onto the shapes tile to claim the highest remaining points for that shape.
Once all players have completed the shape the round is over. The tile is placed to the side for endgame scoring. Players put all their pieces back into the pile. A new Impossible Shape tile is drawn and the next round begins.
Components
The total list of components for the game includes:
- A bunch of hexagonal tiles
- A smaller bunch of rhombus tiles (I’ll explain why in a moment)
- The “Impossible Shape” tiles
- Rulebook
It’s a relatively simple design with a succinct components list that should make it relatively risk-free and publisher friendly.
Why Rhombuses?
Because players can create the impossible shapes in different ways it leads to the need for many different designs on the hexagonal tiles. A simpler solution was to have “correction tiles,” which in this case are rhombuses.
Here is an example based on the image above. In the example a player is working on the left half of the image above. In their haste they grabbed the wrong tile for the upper corner. But instead of wasting precious time searching for the correct tile they realize that they can place an orange/purple rhombus over the wrong part of the tile. This allows them to have an accurate representation of the impossible shape.

The player uses a correction tile to make the shape correct.
The downside of the correction tiles is that each one is worth -1 points. So players should try to avoid them.
How to Win
Below is an example of an Impossible Shape tile. The first person to complete it will receive 7 points at the end of the game. The second player will receive 4 and the third will receive 2.
After a number of rounds agreed upon at the start of the game, all the points will be tallied and the winner will be determined.
Overall Impossible is a fast paced real-time game where you are racing against your opponents to build impossible shapes. Do you have the mind it takes to figure out the shapes and grab the right hex tiles? I’m pretty excited for this game and I’m looking forward to seeing where it ends up.
Thanks for reading! Let me know what you think about the design.
Impossible!
No, the title doesn’t refer to your shock that there’s actually a new blog post on Boards & Barley. Instead it refers to a new abstract game design of mine.
When I was a child I found a small print of M.C. Escher’s Waterfall Lithograph in my dad’s at-home office. At first I thought it was kind of neat but after a few minutes I realized how truly awesome the artwork was. There is an impossibility in the physical concepts of a waterfall flowing uphill. But yet this artwork makes it actually appear possible.
M.C. Escher has long been an inspiration of mine. I love trying to wrap my mind around the 2D artwork that portrays 3D impossibilities.
So I decided to make an abstract tile placement game around that concept. It is based on an impossibility that occurs in the waterfall lithograph. That impossibility is known as the Penrose Triangle. While I’m not using it exactly, I am using the fundamental idea of the Penrose triangle. I’ll show you below.
But first, because I have an illness where I must create a logo for any game design I am working on, here is the prototype logo:
The game is currently still in the concept phase. I have been trying to work out some “Euro-y” type scoring conditions but I’ll have to playtest it before I decide if they should be public goals or private goals, or a combination of both.
Here is an example scoring condition:
If players build a nodelink matching these colors then they will earn the points shown on the card. The first player to build such a nodelink would earn the 4 points while the second player would earn 4 points.
I currently have a bunch of different scoring conditions based on the nodes that will be built during the game. I’m looking forward to playtesting it and figuring out some of the balance about these cards.
The basic gameplay is simple. It’s sort of a mix between Carcassonne and Qwirkle. Players will play 1 tile anywhere that it fits onto the board. Nodes will be built up this way. Once a node is completed, it’s color is determined by whichever color is of a majority at the node.
There will also be one-time use bonuses that allow players to play more than one tile at a time. These should allow for players to make awesome moves in the game and have rewarding moments. My hope is that it also allows for some “take-that” type action where you can mess with something that other players are working on.
That’s the current status of Impossible. I will be bringing the prototype to Gen Con and I’m hoping to get it in front of some people. Thanks for reading and let me know if you have any questions.
