About This Game

Professor Rat loves physics puzzles and games with robots! Therefore, he created Robby, but gave him a weak battery, which is why the little robot has to constantly recharge and participate in crazy experiments.

  • Over 180 levels for your brain!
  • Level Editor and Collection of QR Levels
  • Online database "Community Levels"
  • Various skins for the robot!
  • 4 fun game modes
  • Realistic physics
  • Lots of cartoons!
  • Leaderboard

Features

  • Family-friendly with a 6+ age rating.
  • Designed for horizontal play, best experienced on desktop or tablet.
  • Localized in 18 languages for global players.
  • Cloud saves. Your progress carries across devices and sessions.
  • Global leaderboards to compare your scores with other players.
  • Optional in-game purchases available. The core game is free.

Tips for Players

  • Steady, clean play usually beats aggressive, risky play. Consistency compounds over time, and avoiding mistakes matters more than chasing big moments.
  • If there are multiple modes or difficulty levels, start on default. It is tuned for first-time players and gives you the experience the developer intended.
  • Work backward from the goal. Sometimes knowing where you need to end up makes the starting moves obvious.
  • Play a few complete rounds before looking up guides. Your own observations about the game's systems are more useful than generic advice written for someone else.
  • If a solution seems impossibly complex, you are probably overthinking it. Step back and look for the simplest possible approach first.
  • Count the available moves before you start. Knowing the budget changes how you approach the solution.
  • Audio cues exist for a reason. Play with sound on at least once to learn what the game communicates through audio versus visuals.

Playing Heart Box

Interact with various physical objects to guide robot Robby through all of Professor Rat's puzzle rooms and free him from the charger! Don't want to play the game? Then create your own amazing puzzles in the Level Editor!
