What you can use it for

Use a fast reaction game to make products, campaign symbols, or learning cues memorable. It works well at booths and while visitors wait because one round has an obvious objective and a fixed end. Positive and negative objects can turn a message into a simple “catch this, avoid that” challenge, while scores encourage replay without requiring a long explanation.

What it looks like

Set each falling item's score, starting speed, acceleration frequency, and acceleration rate. You can also enable double-value items.

The timer controls the round length and its visual treatment.

Use the workspace to preview the game and the item list to maintain artwork and scores.

How it works

Items fall through the play area while the player moves the catcher. Contact adds or subtracts the score assigned to that item. Speed settings control how quickly the challenge escalates, and the timer ends the round. The result should explain the final score or the next action rather than leaving a number without context.

Difficulty is a combination of item size, fall speed, acceleration, visual contrast, and round length. Change one variable at a time and test on a phone.

How to get started

1. Choose a theme and define what should be caught and avoided.
2. Upload visually distinct item artwork and assign deliberate scores.
3. Set a forgiving starting speed and a short round duration.
4. Add instructions that explain movement and scoring in one sentence.
5. Preview on mobile, then adjust speed and item size before changing the timer.
6. Write a result page that interprets the score and gives a clear next step.

FAQ

How long should one round be? Keep the first version short enough to replay. Test the actual audience and venue conditions.

Can some items reduce the score? Yes. Use negative values and make those objects visually unmistakable.

What makes the game harder? Higher speed, faster acceleration, smaller objects, and less visual contrast all increase difficulty.
