03 Games and scores

Cells as playing field for games

A playing field for games based on cells such as tic tac toe, battleship etc can be created with the grid boxes that mature by the crossing rubber bands. The ‘game board borders’ can be marked with high rubber bands. The default distance of two centimetres for the cell size is enough, but reconfiguring the  rubber bands to a cell size of three centimetres offers more space.

Yahtzee

Keep the scores for Yahtzee by marking the cells of the first column as 1 to 6 and further down as three of a kind, four of a kind, full house, small and large Straight, free choice and Yahtzee. In the first column you can use regular characters or some tactile graphics that are meaningful for you so you can identify the categories. For the first game we use the second column for the scores per category. For the next games use the next columns. The scores one to six are all kept in one cell.

• Draw a line along the lefthand side of the cell for score one.
• Draw a line along the bottom side of the cell as well for score two. For three a line along the right hand side etc.
• For score five and six you can create diagonal lines in the cell.
• For a missed category provide a line from one side to the other in the middle of the cell.

Gas-Water-Electricity puzzle

Ideally we would like to have gas, water and electricity available in our homes.
In this challenge there are these three resources that you have to provide to three houses under the condition that the (pipe) lines may NOT intersect!

Steps

• Place the GraphGrid on the drawing board.
• Find the cell in the third column and third row and trace the inner contour. This is the gas supply.
• Skip three cells down and trace the inner contour of the third cell, which is the water supply.
• Skip three more cells down and trace the third cell as the electricity supply.
• The three resources are all in the same column.
• Skip three columns to the right and create the squares similar as before. The houses are in one column.
• Take the GraphGrid away.
• Now provide every house with non-intersecting pipelines with all three resources.
