Project Overview

Memory Sequence is a polished, production-ready Flutter game template built for CodeCanyon distribution. It challenges players to memorize 8 shuffled brand images displayed in a 4×4 grid, then recall the exact positions from memory under a countdown timer. The result screen delivers a detailed accuracy comparison and celebrates new personal bests with a gold NEW BEST! badge.

The project ships with complete Google AdMob integration (Banner, Interstitial & Rewarded ads), a top-10 leaderboard, full Dark/Light mode theming, pause/resume game state, and a step-by-step SETUP.md guide — everything a buyer needs to publish immediately.

Key Features

Sequence Memory Challenge

Memorize 8 randomly shuffled branded images in a 4×4 grid within a 15-second countdown, then tap them in order during the 60-second recall phase.

⏱️

Dual-Phase Timer

Separate timers for Memorize (15s) and Recall (60s) phases. Timer turns red when running critical. AnimatedSwitcher ensures smooth digit transitions.

5-Tier Accuracy Rating

Score calculated by exact positional match (0–8). Five performance tiers from Perfect Memory to Keep Practicing with emoji and progress bar.

Shuffle & Recall

After memorization, images shuffle into a new random order. Players must tap them back in their memorized sequence from a numbered slot row.

Leaderboard & Best Score

Top-10 local leaderboard sorted by score with player name, accuracy %, and date. Gold/silver/bronze highlights for the top 3. Best Score persisted on Home Screen. Available with all license types.

Pause / Resume / Quit

Full game-state control. Pause dialog blurs the grid (opacity 0.1). Quit confirmation prevents accidental navigation during an active game.

Dark & Light Mode

Global theme toggle persisted to SharedPreferences. Deep purple dark palette with glassmorphism cards; soft lavender light background with white cards.

Premium Animations

Glowing pulsing brain icon, staggered fade-slide entry animations, scale-press button feedback, animated splash screen, and smooth result card entrance.
