The Bird Sort Puzzle Unity Source Code is a complete, fully functional color sorting puzzle game template built in Unity, ready to publish on Android and iOS. It takes one of the most played and most downloaded casual game mechanics of recent years — the sort-and-group puzzle — and wraps it in a charming, visually distinctive bird-themed world that gives your game an immediate identity on the Play Store.
This is not a prototype or a concept project. It is a polished, production-ready Unity puzzle game source code with working gameplay logic, smooth animations, a complete level system, mobile-optimized performance, and a monetization-ready architecture that supports AdMob rewarded ads, interstitial ads, and in-app purchases. Every screen a player will see — from the main menu to the level select to the win celebration — is already designed, implemented, and functional.
Whether you are a beginner publishing your very first Android game, a freelance developer fulfilling a client brief, or an indie studio building a catalog of casual titles from reskinnable templates, the Bird Sort Puzzle template gives you a professional foundation that eliminates months of mechanical and structural development work.
If you are still learning the foundations of Unity game development and want a step-by-step walkthrough of how games are built and published from scratch, start with the complete beginner resource: How to Make Games in Unity – Complete Beginner Guide for Mobile Game Development. It covers everything from downloading Unity Hub and creating your first project to building APKs and publishing on Google Play — and reading it alongside this template will significantly accelerate your understanding of how professional Unity projects are structured.
Before we get into what this template contains, it is worth understanding exactly why color sort puzzle games have become one of the most reliable and profitable categories in mobile gaming.
The mechanic is globally legible in under three seconds. Players see birds on branches, understand that matching colors belong together, and immediately begin solving. There are no tutorials, no instruction screens, no gameplay explanations needed. The visual design communicates the entire rule set at a glance — which is why color sort games achieve some of the lowest Day 1 drop-off rates of any mobile game category.
Relaxed gameplay generates extraordinarily long sessions. Unlike action games that demand constant reflexes or social games that pressure players into spending, color sort puzzle games create a calm, focused experience where players think at their own pace. The absence of a timer removes anxiety while preserving challenge. This creates meditative, extended play sessions that translate directly into higher ad impression counts and better AdMob revenue per daily active user.
The "one more level" psychology is exceptionally strong. Each level ends with a clear resolution — either every bird is sorted correctly and the board is solved, or it isn't. This binary satisfaction creates a powerful psychological pull toward the next level. Players consistently report intending to play one or two levels and finding themselves thirty minutes later. This retention characteristic is the foundation of long-term game performance on Google Play.
Level design is the only real differentiator. Because the core mechanic is identical across competing color sort games, the game that wins is the game with the most thoughtfully designed, difficulty-balanced level progression. This template's level system gives you complete control over that progression — which means your version can be genuinely better than competitors with the same mechanic.
The audience is enormous and underserved by quality titles. Color sort puzzle games attract an audience that skews toward women over 25, casual gamers, puzzle enthusiasts, and players who want mindful entertainment rather than competitive stress. This demographic is exceptionally large on mobile, spends significant time in games, and responds strongly to both AdMob rewarded formats and cosmetic in-app purchases.
Production cost is low relative to revenue potential. Color sort puzzle games are 2D, use simple character animations, and require no complex physics or AI systems. The Bird Sort Puzzle template takes this inherently manageable scope and pre-builds all the difficult parts. Your investment in customization and level design can realistically yield a long-running, passive-revenue mobile game.
The Bird Sort Puzzle mechanic is deceptively simple and genuinely satisfying to play.
Each puzzle presents a collection of branches — vertical perches arranged in a grid pattern — populated with colorful birds stacked several deep on each branch. Multiple bird colors are distributed across all branches, mixed together in an unsorted state. One or two branches are left empty at the start, providing the working space needed to begin organizing.
Players tap a bird on any branch to select it. The bird is then moved to another branch of their choice. A move is valid only if the destination branch is either empty or has a bird of the matching color sitting on top. A move is invalid if the destination branch is full or if the top bird doesn't match — clear visual and audio feedback communicates this immediately without punishing the player harshly.
The puzzle is solved when every branch contains only one color of bird from bottom to top. No mixed branches. No incomplete groupings. Full, sorted stacks. When the final bird lands in its correct position and the last branch completes, the win animation plays — a satisfying cascade of celebration that rewards the player's logic and planning.
Easy early levels can be solved with minimal planning. As levels progress, the number of branches increases, the number of colors grows, and the initial distribution becomes more complex. Advanced levels require players to think several moves ahead — recognizing that moving bird A now blocks bird B later, and that the correct sequence is the only path to a clean solution. This strategic depth is what keeps players engaged past the first twenty levels and what creates the strong replay motivation to retry levels they fail.
There is no countdown clock. There is no failure state from thinking too long. Players can put their phone down, come back, and continue solving where they left off. This stress-free design is a deliberate choice that makes the game accessible to players who find time-pressured puzzles frustrating — expanding the potential audience significantly.
Every system in this bird sort color puzzle Unity game template is implemented, tested, and ready to build on.
The core gameplay engine handles all mechanical logic of the sort puzzle: valid move detection, branch capacity tracking, color matching verification, move execution with animation, and win condition evaluation after every move. The interaction system uses Unity's touch detection and raycasting to identify which branch the player taps with precision across all screen sizes and aspect ratios.
Move validity checks run in a single frame — there is no delay between player input and feedback. Valid moves trigger the movement animation immediately. Invalid moves trigger a shake animation on the selected bird and a short audio cue, communicating the error without interrupting flow.
The template includes a complete level progression system with a level select screen showing all available stages. Each level has an independent data structure defining the number of branches, the number of colors, the initial distribution of birds, and the empty branch count. The level system supports any number of levels — your content library scales as large as you build it.
Level data is stored in structured ScriptableObjects, making level design a clean data-editing task rather than a code-modification task. New levels can be created, tested, and added to the progression without touching any gameplay scripts.
Levels are locked until the previous stage is completed. Each level awards a star rating based on the number of moves used relative to an optimal move count — three stars for efficient solving, two stars for moderate, one star for completing with maximum moves. The star system provides a secondary challenge layer that drives experienced players to replay levels and improve their efficiency.
Locked stages display a preview of the bird color distribution, giving players a sense of the challenge ahead and motivating progression.
Players can undo their last move with a dedicated undo button in the gameplay HUD. The undo system rolls back the move animation, restores the bird to its previous branch, and reverts the game state completely. Multiple undos are supported in sequence, allowing players to backtrack several steps when they realize a move sequence is leading to a dead end.
The undo button can be connected to the AdMob rewarded ad system — players get a limited number of free undos per level, with additional undos available by watching a rewarded video. This creates a natural, non-intrusive monetization touchpoint at exactly the moment players are most motivated to engage with it.
A hint button analyzes the current board state and highlights a valid next move. The hint system is designed to unblock stuck players rather than solve the puzzle for them — it identifies one beneficial move, not the complete solution path. This keeps the satisfaction of solving intact while preventing frustration-driven uninstalls.
Like the undo system, hints connect naturally to the AdMob rewarded ad format — a limited number of free hints per level, with additional hints available via rewarded video. Hint usage converts at high rates because players who are stuck are highly motivated to continue.
The template includes a thoroughly structured AdMob monetization system:
Rewarded Ads — Undo Expansion: When a player uses their free undos, a rewarded video prompt offers additional undos in exchange for watching an ad. Players willingly watch because they are invested in solving the current puzzle.
Rewarded Ads — Hint Unlock: Same structure as undo expansion. One of the highest-converting rewarded ad placements in the puzzle genre because stuck players have a strong emotional reason to engage.
Rewarded Ads — Level Skip: Optional — offer players the ability to skip a frustratingly difficult level in exchange for watching a rewarded video. This reduces frustration-driven uninstalls and generates ad revenue simultaneously.
Interstitial Ads — Between Levels: Displayed after a configurable number of level completions. A fully configurable frequency cap prevents over-serving. The natural break between levels is the least intrusive interstitial placement in mobile gaming.
In-App Purchases — Hint and Undo Packs: The template's IAP framework supports selling hint packs and undo packs as one-time purchases. Players who are engaged enough to buy are your highest-value users — giving them a paid option alongside the rewarded ad option serves both spending profiles.
All AdMob and IAP placements are clearly documented in the code with comments showing exactly where configuration values go. Test ad unit IDs are pre-configured for development. Switching to live production IDs requires changing a single configuration asset.
The bird characters are the visual heart of this game. Each color variant has a distinct, charming design — expressive, round, and personality-rich in the way that casual puzzle game characters need to be to create emotional connection with players. The art style hits the exact visual register that performs well with casual puzzle audiences: bright, colorful, friendly, and immediately readable at small screen sizes.
The character sprite system is organized for reskinning — all bird color variants are stored in a single atlas with clear naming conventions. Replacing the bird art with a different character theme (cats, bears, gems, fruits, or any other concept) requires updating the sprite atlas without touching any gameplay code.
Every meaningful game moment has visual reinforcement: branch completion triggers a burst of color particles; the level win triggers a full-screen celebration effect with confetti and animated stars; the undo action has a subtle rewind visual; invalid move attempts trigger a gentle red flash on the branch. These micro-effects create the tactile satisfaction that makes puzzle games feel rewarding to interact with, not just cognitively engaging.
All particle systems are tuned for mobile GPU budgets — visually impactful without performance impact on mid-range Android devices.
The audio layer covers every meaningful game event: bird movement sounds with satisfying placement audio when a bird lands correctly, mismatch audio for invalid moves, branch completion chimes that escalate in pitch with each branch cleared, the full win audio sequence, undo and hint usage sounds, button press sounds, and looping background music with smooth fade transitions between game states.
All audio is routed through a central AudioManager. Music and sound effects are independently toggleable through the settings menu, which is already implemented.
Every screen is designed, implemented, and functional:
The template is pre-optimized for the full Android device range:
The codebase follows single-responsibility design principles throughout:
Every public method includes XML documentation comments. The architecture is beginner-readable and expert-extensible simultaneously.
The template is specifically designed for fast visual reskinning:
A complete visual reskin — different characters, different color palette, different UI theme, different name — can be executed in two to three days without modifying any C# scripts.

Can I change the birds to a different character theme — cats, gems, fruits?
Yes, and this is specifically designed to be easy. All bird character sprites are in one clearly organized atlas. Replacing the atlas with a different character set changes the game's visual identity entirely without touching any gameplay code. The color identification system is based on color enum values, not sprite names — new characters simply need to maintain the same color categorization structure.
How many levels are included out of the box?
The template includes a starter set of levels demonstrating the full range of difficulty progression — from simple introductory puzzles to complex multi-color challenges. The ScriptableObject level system makes adding additional levels fast: define the branch count, color count, and initial bird distribution, assign it a level number, and it appears in the level select screen automatically.
Does the undo and hint system support rewarded ad integration?
Yes. The undo and hint systems have built-in hooks for AdMob rewarded ads. The integration points are clearly marked in both HintSystem.cs and the undo handler. Connecting your AdMob rewarded ad unit ID to these hooks requires minimal code adjustment and is documented step by step in the included documentation.
Is this suitable for publishing on iOS as well as Android?
Yes. The project is cross-platform and exports to both Android and iOS. iOS builds require a Mac with Xcode. If you need iOS support without a Mac, the iOS Build Service add-on handles the complete iOS build and submission process.
How difficult is it to design new levels?
New levels are created by filling out a ScriptableObject data asset in the Unity Inspector — no scripting required. You specify the number of branches, the number of colors, and which color appears in which position on each branch. The level immediately becomes playable and testable in the Unity editor without building an APK.
Can I use this template to publish multiple different color sort games?
The Regular License covers one published application. If you intend to publish multiple reskins of this template — different visual themes, different character art, marketed as separate games — the Extended License covers this use case and provides the appropriate commercial rights.
What level of Unity experience do I need?
Intermediate Unity experience is sufficient for customization and publishing. If you are a complete beginner, reading the How to Make Games in Unity complete guide alongside working with this project will give you everything you need to understand the project structure, customize it, and build your first APK.
