エコペン探検隊　どうくつ探検バトル (Eco-pen Expedition Team: Cave Exploration Battle)

Players compete across three maze-like maps. All pieces move in the same direction, so initial placement and timing matter as each player tries to avoid being trapped and interfere with the opponent.

The first player to get two pieces out of the map wins. The maps can be placed vertically or horizontally and can be played on both sides, providing different setups.
