Taggle is a two player game of tag/hide and seek, where one of the players, the Collector, can toggle his/her visibility.
It’s the Collector’s job to collect little bits (cubes), and the Chaser’s job (the other player), to tag the Collector.
When the tag is made, the players switch roles. The first player to collect 10 bits wins.
Perhaps the entry page for the game describes it better
Enjoy
