I made the following mat originally because I did not care for the paper money and wanted an alternative means of money counting. I expanded the mat to include three things:
1. Three spaces for placing your power plants as you purchase them. There is a fourth space that includes the payments, though this space can also be used for a fourth power plant in a two-player game.
2. Elektro Counter Board: Instead of using money, there are two sets of counter spots: one ranging from 0-9, one ranging from 00-190. To keep track of your money, put one counter in the single digits and one in the multiples of ten (so, for example, if you have 57 Elektro, you'd put one in the 7 and one in the 50). Slide them up and down as necessary. The spaces are designed to be used with the houses included in the game (since you are unlikely to use them in most games with more than two players), but any small (1 cm) counter or chip works.
3. A brief summary of the turns. (Between this and the fourth power plant space above, you won't need to use the summary cards included in the game.)
Simply print the mats, cut them to 6x9" (which fit nicely in the original game box), and laminate them if you are so inclined.
Wherever possible, I tried to maintain the aesthetic of the original, using the original fonts as I could and matching the colors to the downloadable rules guide. Rights to the original images remain with the publishers.
