An AR Fruit Ninja game you play with your hands

No mouse. No taps.

Just move your hand through the air to slice.

Your webcam tracks your motion, your finger becomes the blade.

How it came together

I didn’t start by building the full game.

I started by asking one question:

Can I even track a hand reliably enough to slice?

So I stripped everything down and tested just the tracking.

A few of the iterations

• Started with simple circles instead of fruits → just to validate slicing detection

• Once that worked, replaced them with actual fruits

• Used fruit emojis instead of designing assets → instant high-res visuals, zero design time

• Tweaked fruit size and speed multiple times to make slicing feel satisfying

• Added a trail to the hand → gives visual feedback for slicing motion

• Replaced “Start” click with a swipe interaction → slide to begin using your hand

• Added bombs to introduce risk and decision-making

• Introduced a 3-life system → miss or hit a bomb, you lose a life

• Added scoring to complete the game loop

Big challenges

Validating the core interaction first

Instead of jumping into visuals, I focused only on tracking accuracy.

If slicing didn’t feel right, nothing else mattered.

Making onboarding feel natural

Instead of a button click, I used a hand swipe to start the game.

It doubles as onboarding, users instantly understand how to interact.

Making slicing feel real

Fruit slicing wasn’t straightforward.

Emojis had to split and move in a way that actually feels like a cut.

Getting that motion right took iteration, but that’s what makes it satisfying.

Balancing speed vs control

Too fast → frustrating

Too slow → boring

Finding the right speed + size combo took multiple iterations to feel right.

Making it feel like a real game

Without stakes, it felt like a demo.

Bombs, lives, and scoring turned it into an actual game.

Try it

→ Works best on desktop with good lighting
