Valentine Memory

Inspiration

Memory Match was inspired by classic memory card games we all played as kids — but reimagined as a competitive, social experience for Snapchat.

I wanted to combine the nostalgia of memory games with the turn-based challenge format, where two friends can compete head-to-head without needing to be online at the same time.

The Valentine's theme felt perfect: hearts, love, and a playful rivalry between friends.

What it does

Memory Match is a turn-based memory game where two players compete to find all matching pairs in the shortest time.

Here's how it works:

The game shows 12 cards featuring the player's own Bitmoji in Valentine-themed poses
Players have a few seconds to memorize the card positions
Cards flip face-down, and the timer starts
Players tap cards to reveal them and find matching pairs
Once all 6 pairs are found, the timer stops
The player sends a Snap to challenge a friend
The friend plays the same game, and the best time wins

At the end, Bitmoji animations celebrate the winner — or console the loser!

How I built it

Memory Match was built entirely in Lens Studio using JavaScript.

Key features include:

Bitmoji Sticker integration using TurnBasedPlayerInfo to display each player's personalized avatar
Turn-based system to pass the game state between players via Snaps
Memorization phase with animated "Memorize" text before gameplay starts
Real-time timer tracking each player's performance
Pair matching logic with animations: correct pairs scale up, incorrect pairs flip back
Haptic feedback (TapticEngine) when a match is found
Winner/loser screen comparing both players' times with animated Bitmoji results

All game state (player times, winner) is saved and transferred using Snapchat's Turn Based API with persistent User and Global Variables.

Challenges I ran into

One major challenge was preventing race conditions when players tap cards too fast. Tapping three or more cards simultaneously caused animations to break and cards to lock up.

Another challenge was dynamically switching Bitmoji between players.

Accomplishments that I'm proud of

Building a fully functional turn-based multiplayer game in Lens Studio
Integrating personalized Bitmoji that adapt to each player automatically
Creating smooth card flip, scale, and result animations
Delivering a polished Valentine's theme with haptic feedback and animated UI

What I learned

Through Memory Match, I learned how to:

Use TurnBasedPlayerInfo to dynamically load different users' Bitmoji at runtime
Manage asynchronous game state between two players using Turn Based Variables

This project strengthened my understanding of turn-based mechanics, Bitmoji integration, and state management in Lens Studio.
