Standard TM hills are made using 1" hexes (TM3), but steep hills use 1½" hexes (TM4). Gentle, rolling terrain is made using ½" (TM1) hexes. In each case, after cutting the hex into two slope pieces, the slopes are glued to a base ½" hex. There are 3 different cuts possible (all illustrated in the instructions with each pack of TM3 and TM4), which produce 5 different geo-morphic slope shapes. By rearranging these, an infinite set of hill patterns can be achieved. Since they are separate hexes, they can be repositioned into a new board for the next gaming scenario.
