Looking for Free Online Games that sharpen problem solving while staying fun? Heart Box drops you into experimental rooms where you must free a stranded robot using real world physics, timing, and a bit of creativity
Guide a brave little robot through labs built by Professor Rat. Each level mixes interactive items and hazards, from trampolines and conveyor belts to lasers and dynamite. Fans of thoughtful challenges will feel at home in our puzzle games; if you prefer quick reflex twists, browse arcade games too
🧩 20+ interactive gadgets, test cubes, bowling balls, spring trampolines, movable platforms
⚙️ Dynamic systems, conveyor belts, pneumatic tubes, gravity tricks, timed switches
💥 Real risks, saws, lasers, and dynamite that demand precise planning
🧠 Escalating difficulty, puzzles grow deeper with multi step solutions and timing chains
🏅 Replay appeal, optimize routes for faster clears and higher scores
Release the robot from its charger and reach the exit using level objects, timing, and physics
🖱️ Click or 👆 tap to interact, drag to place or rotate objects, and toggle switches
⏱️ Trigger mechanisms in sequence to chain movements and create safe paths
🔎 Survey first, identify hazards and must use gadgets before touching anything
📐 Build a path, combine ramps, platforms, and trampolines to control momentum
⏰ Time releases, drop cubes or activate belts at the moment they help, not hinder
♻️ Iterate quickly, small tweaks to angle, height, or timing often solve the room
🟫 Test cubes, add weight to switches or counterbalance platforms
🟡 Trampolines, convert vertical drops into horizontal launches
🔁 Conveyors, maintain speed and direction through tricky sections
📦 Movable platforms, bridge gaps or create safe landing zones
💨 Pneumatic tubes, fast transport, mind the exit trajectory
🔴 Lasers and saws, avoid or block with objects to protect the robot
💣 Dynamite, remove barriers, but shield the robot from the blast
📏 Set angles first, then fine tune distances for consistent bounces
🧲 Use heavy cubes to pin moving hazards or hold buttons reliably
🔄 Reset without hesitation, rapid iteration reveals the correct sequence
🎯 When stuck, work backward from the exit to the charger and fill the gaps
Open a level, examine the room, then drag and place objects to guide the robot. Activate switches, time conveyors, and use trampolines to clear gaps. Release the charger lock and navigate safely to the exit to complete the puzzle

No, it runs directly in your browser
Place platforms to control the first bounce, then add conveyors to maintain speed past hazards
Block with cubes or reroute the robot so the beam never intersects its path
