The Meander Expansion set contains four extra tiles, four marker marbles (two red, two green), and a die. A (very) small booklet gives some variations on the original rules and suggestions to use the components of the expansion set. The four extra pieces (one of each of the basic pieces) can be used to make the tile draw a bit more uncertain. The marbles are used to indicate pockets that count as double or nothing and the die is used before each turn to give you extra actions (or make you lose your turn).Expands: Meander - BoardGameGeek
