First, make a playing field. It is better to take a thick sheet of cardboard or drawing paper that will stand more than a dozen parties. Draw a closed playing field, and then decorate at its discretion the middle of the sheet to make the Board game even more interesting and original. The dimensions of the field, its shape and number of cells also depend on you.
Think how complex is the playing field in your "Monopoly". It can be not a square, but a more complex shape that includes several intersecting paths with arrows indicating which way the player should go. A more complicated version of the game may appeal to experienced players who are tired of standard square field, however for the beginners it can seem complicated.
Decide the playing field is static or dynamic. The first option assumes that the cells of the playing field will appear a variety of symbols. The second option includes the production of cards with symbols and their unfolding on the field at the start of each game. Dynamic playing field makes the game more interesting because with each batch the location of the cards will change. By the way, you can also invent a few special cards not included in the standard set of monopoly.
Select bills. You can make them yourself from paper, cardboard and other materials, and can also take small coins. The easiest, but not the best option – keep score on a sheet of paper. However, this will reduce interest in the game, so this option is suitable only as a temporary measure. Do not forget the figures: let each player will make or choose them yourself.
You can also amend the rules, discussed them with other players. Amendments can be both simplifying and complicating, depending on the experience of each player. The new rules should be written to during the game to avoid disputes and disagreements.
