Catcher
Configure a Catcher game with falling objects, score-based gameplay, and performance rewards.
Run a fast reflex challenge where people catch falling objects for points and compete for the top score. Use Catcher when you want to reward the strongest runs rather than pick a winner instantly.
For example, a retail campaign might ask people to catch branded gift boxes for points while dodging decoys, then crown the highest scores at the end.
Assets you'll need
The catcher plays over a background: good items fall from the top, the player slides a catcher along the bottom to collect them, and traps cost a life. The catcher, the items to catch, and the traps are all 3D models picked from your library.

How rewards work here
Catcher uses Leaderboard rewards. Create the reward in Platform, then link it to this touchpoint in Performance Rewards.
Keep one Leaderboard reward per game. That keeps the ranking clear and avoids confusion over who won.
Before you begin
- You have a Campaign open in Build > Touchpoints.
- Your background, catcher model, catch items, and trap models are uploaded to your media library.
- Your Leaderboard reward is created in Platform, ready to link in the last step.
Steps
Choose the Catcher Game type
In Build > Touchpoints, add a new game touchpoint, then pick Catcher Game from the touchpoint type picker.
Set the page title and subtitle
On the Appearance tab, upload the Background Image, then fill in the Title players see at the top of the game and the Subtitle below it.
Add a Thumbnail if the game also appears on a landing page or in listings. Choose a background that keeps moving objects easy to read on mobile.
Tune the catcher and add the falling objects
Open the Game Settings tab. Under Select an Asset, pick the catcher's 3D model, then adjust how it handles:
- Size — how large the catcher appears on screen.
- Move Speed — how quickly it slides to follow the player's finger.
- Collision Scale — how generous the catch zone is. A higher value makes near-misses count as catches.
Then build what falls during the run:
- Bonus Objects increase the score. Use Add Bonus Object for every item you want people to catch.
- Trap Objects cost the player hearts. Use Add Trap Object only when you want the run to feel harder.
For each object, review its points or heart damage, spawn timing, fall speed, and starting rotation so the challenge feels fair from the first seconds to the last. Use Progression Phases lower on the tab if you want the run to speed up over time.
Add an optional open-ended question
Turn on Enable open-ended question to collect one last response after the run ends.
Leave it off if you only want the score. When it's on, choose whether the answer accepts Text Only, Image Only, or Text and Image.
Link the Leaderboard reward
In the Performance Rewards section, choose Add Reward and pick the Leaderboard reward you created in Platform.
These are the rewards players can win based on their score, so keep a single Leaderboard reward for this game to keep the ranking clear.
Save and test a full run
Choose Save, then play the touchpoint once from the participant view.
Confirm the score feels meaningful, bonus and trap objects are easy to tell apart, and the final summary matches what you want to publish.
What players see at the end
When the run finishes, the optional open-ended question can appear before the summary.
The summary then shows the final score, any remaining hearts, and your Participation Message. This tells the player how the run went, before the campaign later picks the leaderboard winners.
Keep the leaderboard fair
Because Catcher ranks on score, fair games usually:
- make bonus objects easy to recognize at a glance
- use trap objects sparingly and on purpose
- avoid point values that make one object far more important than the rest
- keep one Leaderboard reward for this game only
Before you publish
- the catcher feels comfortable on the devices your audience uses
- every bonus object has a clear scoring role
- every trap object has an obvious penalty if you use traps
- the optional open-ended question is complete if you turned it on
- the linked reward belongs to this game alone
