Watch a balance scale tip and decide which side is heavier or lighter! A rock vs a feather, an elephant vs a butterfly — learn about weight and measurement concepts through an interactive animated scale.
Choose Easy, Medium, or Hard difficulty and pick your game mode
Tap 'Start Weighing!' to begin
Watch the balance scale — it starts level, then tips toward the heavier side
Read the question ('Which is HEAVIER?' or 'Which is LIGHTER?')
Tap the emoji button for the side you think is the answer
The pans glow green (correct) or red (wrong) to show the result
Keep answering to build your streak for bonus points!
Animated balance scale that starts balanced, then smoothly tips toward the heavier side
24 objects across two pools: 12 heavy items (rock, weights, elephant, car…) and 12 light items (feather, balloon, butterfly, leaf…)
Three difficulty levels: Easy (big tip, heavier questions only), Medium (moderate tip, mixed questions), Hard (tiny tip, mixed questions)
Two game modes: 10 Rounds arcade with streak bonuses, and 60-Second Rush for fast-paced practice
Pan colour changes to green/red after each answer to confirm the correct side

Heavy or Light? is an interactive measurement game where a balance scale tips to show which of two objects is heavier. Players watch the scale animate and then identify which side is heavier or lighter — building a foundational understanding of weight and measurement.
Introduces the Balance Scale
Introduces the balance scale as a physical measurement tool — a key concept in early science and math curricula worldwide.
Builds Intuitive Weight Understanding
Builds the intuition that heavier objects make the scale tip down, laying the groundwork for formal measurement vocabulary and concepts.
Real-World Weight Connections
Uses familiar weight associations (rock vs feather, elephant vs butterfly) to connect play with everyday experience, making abstract concepts concrete.
Scales Difficulty Gradually
Three difficulty levels control how much the scale tips — from very obvious to barely perceptible — developing careful visual observation skills.
Practices Both Directions
Both 'heavier' and 'lighter' question types reinforce the same relationship from two perspectives, mirroring how greater-than and less-than work in math.
The brief balanced moment mirrors how a real balance scale works — you place both objects first, then let it settle. It also builds anticipation and makes the tip more dramatic and memorable.
On Easy the scale tips 20–28 degrees (very obvious) and only asks 'heavier' questions. On Medium the tip is 12–20 degrees and mixes heavier/lighter questions. On Hard the tip is just 5–10 degrees, requiring careful observation, and includes both question types.
Yes! Each puzzle always pairs one object from the 'heavy' pool (rock, elephant, car, whale…) with one from the 'light' pool (feather, balloon, butterfly, leaf…), so the winner always matches real-world weight intuition. The difficulty comes from reading how much the scale tips, not guessing the answer.
The game is ideal for ages 4–8. Easy mode suits preschoolers who are just learning that 'heavier goes down.' Medium and Hard add vocabulary (lighter) and observational challenge suitable for early primary school.
