On day one, Critter Creamerybecame the most played game globally across Amazon's FC Games network, capturing 29% of total utilization and bringing 5,000 new associates into the ecosystem.
Problem Space - The Why
Imagine the sound of whirring conveyor belts, clanking metal, and wheels zipping above your head... You just started working at Amazon. Your job is to pick and pack goods for a customer thousands of miles away. Hours pass. Your eyes get heavy. Your mind begins to zone out...

This is the exact problem FC Games solves for...
In 2017, Amazon launched FC Games, an initiative to integrate game mechanics into fulfillment centers. These games provide passive entertainment while associates pick, pack, and sort — without disrupting workflow. The result: increased cognitive engagement, reduced error rates, and improved safety in high-activity environments.
FC Games had been running across thousands of fulfillment centers globally when I got pulled in as design support for a hackathon. Two days later, we won. What I thought was a side project became one of the most played games Amazon has ever shipped.
Design Challenge
The main challenge was creating an engaging game that would fit seamlessly into associates' workflow without distracting them. FC Games has strict rules:
- don't compete
- don't distract
- don't race
I had to ensure the game aligned with Amazon's goals of increasing productivity and reducing downtime, while maintaining safety in the fast-paced environment of fulfillment centers.

Critter Creamery, originally pitched as Froggy's Food Truck, was born out of a hackathon hosted by Amazon's FC Games division. My team won the hackathon, and leadership saw the potential for a full-scale development effort. The game was designed to offer a calming, low-pressure experience where players guide Froggy, a chef crafting unique ice cream flavors, serving customers, and earning in-game currency — all while working their shifts.

My Role and Contributions
As the lead designer, I was responsible for:
- Game mechanics design: Developing the core gameplay loop to provide passive engagement without detracting from the associates' work.
- User research and testing: Conducting minimal usability testing to ensure accessibility and engagement in high-activity environments.
- Asset creation: Designing all characters, locations, and game assets, including reusable animations and ice cream flavors.
- Collaboration with developers: Working closely with the developer throughout the project to refine game mechanics and ensure a cohesive experience.

Game Mechanics and Locations
Critter Creamery was built around two phases:
- Prepping Phase:Players gather ingredients and prepare ice cream based on their task completion in the real world. This phase syncs with associates' daily tasks, allowing for seamless engagement.


- Serving Phase:Customers arrive at Froggy's truck and place orders. As associates complete tasks, they serve ice cream to diverse patrons while they earn Froggy Coins, and unlock new flavors and locations and attract new patrons to their truck.

Each location brought new gameplay elements while keeping the experience relaxing and engaging. Associates' goal is completion and collection with some ice creams earning more money and to take things deeper each ice cream is a patrons “Favorite” this mechanism allows for patrons to tip more money when served their favorite ice cream in term deepening the relationship the character has with the associate adding an additional decision based mechanism as the menu slots are limited.
Key locations included:



Character Design and World-Building in Critter Creamery
The characters in Critter Creamerywere intentionally designed to match the environments of the game's different locations, adding depth to both the gameplay and the overall world-building. As Froggy, the main character, travels to distinct regions such as Forest Frozen Flavors, Riverside Creamery Cove, and Summit Frost Peaks, each area is populated with animals that naturally fit the habitat. For example, the forest location features woodland animals like squirrels, deer, and rabbits, while the riverside introduces aquatic creatures such as otters and frogs. Meanwhile, in the colder mountain region, players encounter mountain goats and snow leopards. This thoughtful alignment between location and character design not only creates a more immersive world but also helps tell the story of Froggy's culinary journey through these varied environments.
Each animal character also comes with its own unique logbook, tracking their preferences, stats, and achievements. Players can build relationships with the animals by serving them their favorite ice cream flavors, unlocking special achievements and story elements as they progress.
For instance, each animal has a specific flavor preference—whether it's a fruity option or something rich like chocolate—which allows for personalized interactions. The more an animal's preferences are met, the deeper the relationship becomes, unlocking rewards such as rare ingredients or special items, and sometimes revealing hidden aspects of Froggy's story.


Concept Development and Hackathon Success

The initial concept for Critter Creamery came from the Amazon FC Games hackathon. Tasked with creating a new game to engage associates, my team conceptualized Froggy's Food Truck as a calming, cozy game inspired by the rise in popularity of cozy games like Stardew Valley andAnimal Crossing. The game centered on Froggy, a traveling chef who serves ice cream to patrons. Our approach, which emphasized relaxation and progression rather than competition, resonated with the judges. After winning the hackathon, Amazon leadership saw the potential in the concept and decided to expand the project for global rollout.

Feedback and Iteration
User Acceptance Testing (UAT) sessions provided valuable feedback from associates on the game's progression speed and engagement. Initial feedback indicated that the game's progression felt too slow, which led to several iterations. We introduced relationship-building mechanics, where serving patrons their favorite ice cream flavors boosted their engagement and unlocked additional rewards.
In addition, I collaborated closely with developers to refine the game's animations and mechanics. I created reusable animations for tasks like stirring, chopping, and serving, allowing the team to easily expand the game without needing to create entirely new assets for each action. This modular approach streamlined development and ensured visual consistency across all game elements.
Challenges and Iterations
An early challenge was rebranding the game from Froggy's Food Truck to Critter Creamery due to intellectual property concerns. Despite the legal rebranding, the core gameplay mechanics and aesthetic remained intact.
Another key challenge was balancing the game's pacing to ensure it provided passive engagement without becoming too slow or frustrating for players. This was resolved by introducing new mechanics and consumable features, such as coffee beans, to give players the ability to speed up certain actions and add variety to the gameplay.

Outcome and Impact
Critter Creamery became the most-played game across multiple fulfillment centers globally, outperforming other activities in the FC Gamesnetwork. It's now available in major locations, including Tokyo, Berlin, Paris, and London. Feedback from associates has been overwhelmingly positive, with many requesting further customization options and new game content.

Metrics:
- Top-played game globally across multiple FCs.
- 55 engagements in a single day at a key site beta.
- Positive user feedback, with associates asking for more locations, ice cream flavors, and customization options.
- As of October 2024
Associates have praised the game for being “extremely cute” and commended its graphics as the “best from all the games.” The introduction of Critter Creamery even coincided with the discontinuation of Space Race, a previous offering, further emphasizing the success and demand for the new content. The data reflects that Critter Creameryhas set a new standard for engagement and enjoyment among FC associates, making it a standout success in Amazon's game catalogue.
From Game Character to Global Mascot
Due to the success of the game and the popularity of Froggy, the character was adopted as the mascot for FC Games onboarding. I designed 16 custom Froggy emotes, which are now used in training and onboarding scripts across fulfillment centers. Froggy's playful style and personality have become a beloved part of the FC Games culture.







Sample emotes from the 16-emote set: Angry, Thinking, Love, Confident, Bored, Excited
Player Reception
Beyond the metrics, the most meaningful part of this journey was the profound attachment it fostered. I was moved to find Reddit communities where seasonal workers expressed genuine grief at the thought of leaving their “patrons” when their contracts ended. It became more than just a game; it was a ritual that I feel privileged to have contributed to the workday.
