My words literally betray me.
In Masterplan, players take turns placing houses onto a 8x8 square grid. Houses can be placed at the sides or in the corners of the squares. Whenever three houses are in a row (no matter in which colour combination), a green flat piece is placed at either end. Players who have the majority of adjacent pieces to these flat ones score at this moment. The majority depends on whether a house is placed on the line directly adjacent to this space (2 points) or at the corner (if diagonally adjacent, valued 2 points) or only on the adjacent space, but at another line or corner (1 point). Whenever a full square of houses could be build (3 houses creating an "l") a tower is placed onto the fourth space. These towers score only at the end of the game, depending on the majority around them.
This doesn't seem correct at all.
A park (green flat) is placed any time a row of 4 houses could be completed by somebody on their next turn. (not just 3 in a row). The park score immediately, every adjacent piece scores 1 pt. Every directly adjacent (on the side closest or corner closest to the park) piece scores 1 extra point.
If somebody could complete a 2x2 grid of houses on their next turn (3 houses creating an "L"), a tower is placed (assuming there are any left). Towers score at the end of the game. To person who has the most influence next to a tower scores 2 pts at the end of the game. Influence is determined in the same way that parks are scored. (1 pt for adjacent + 1 additional pt for directly adjacent.)
The game looks very cool.
