CHALLENGE (ZELLERS) (ATARI 2600)

In Challenge, players take control of a duck. The duck can only move vertically until it reaches the top or bottom of a column, then it can move left to reach the next column. The columns are interspersed with rows. These rows contain creatures that continually come and go. Players must move up and down between these columns while avoiding the patrolling creatures. Successfully navigating through all columns within the six minute time limit completes a stage. Completing a stage gains an extra life on top of the six lives the player starts the game with and takes the player to the next stage which has increased difficulty due to the addition of more creatures.
