Many abstract strategy games are also combinatorial, i.e. they provide perfect information, and rely on neither physical dexterity nor random elements such as rolling dice or drawing cards or tiles.
In symmetric blockade games, both players have the same number of pieces with the same movement capabilities.
This could involve forming a path between two or more goals, completing a closed loop, or connecting all of one's pieces so they are adjacent to each other.
These games involve some aspect of counting, especially to determine the relative outcomes of various alternatives at points along the way.
These games include hidden information or setup, random elements (e.g. rolling dice or drawing cards or tiles) or simultaneous movement.
