Bonanza Bros.

Mobo and Robo Bonanza are watching their favorite TV show when a mysterious stranger appears on screen, asking for their help in collecting items from various buildings. The stranger wants Mobo and Robo to retrieve certain objects within three minutes, or they won't receive the $100 reward.

As you play as either Mobo or Robo, your goal is to collect all the treasures before leaving the ten buildings and avoiding security guards who will sound the alarm if caught. You have a limited time to complete this task, with an in-game map helping you locate the items. Additionally, there are bonus stages after three buildings where you need to collect gold bars within a time limit while avoiding spotlights; hiding behind open doors can help you succeed.
