A game comprising a submersible retrieving submarine adapted to receive and interpret RF directional command signals, an RF transmitting remote controller adapted for sending such signals to cause the craft to submerge and then cause the submerged craft to move in selected underwater directions, and targets of assigned values adapted for standing on the underwater bottom. The craft is adapted with a hook for engaging the targets and carrying them to the water's surface so that the accumulated value of the collected targets can be tallied to provide a score. One or more players can compete to tally the highest score, using either one controller/submarine set consecutively, or two sets simultaneously.
