Project Overview

PicA Puzzle is a mobile gaming platform that turns user-generated photography into interactive sliding puzzles with progressive difficulties, leaderboards, and secure sharing capabilities.

The Business Challenge

Players exploited the daily rewarded ad limits and game timers by setting their mobile device clocks backward. High concurrency operations also triggered profile validation crashes for guest accounts on launch.

Our Solution & Engineering

We developed a Flutter application leveraging Riverpod for state management. To counter time-travel cheating, we implemented a Supabase RPC check (`record_and_check_ad_watch`) that logs ad timestamps server-side. Guest accounts benefit from a self-healing signup profile checkpoint, and XP values fall back to local SharedPreferences when offline.

Key Integrations

Secure Puzzle Encryption

Encrypts user photos end-to-end so puzzles can be shared privately via SMS or WhatsApp fallback links.

Server-Side Ad Verification

Monitors daily video ad completions against a secure Supabase ledger, making client-side tampering impossible.

Dynamic XP Hint Engine

Features Image Glimpses and animated Auto-Solve piece swaps triggered dynamically by Riverpod.
