How to Reskin a Unity Game: Step-by-Step Guide (2026)

October 10, 2026 · 6 min read

Buying a ready-made Unity game is the fastest way to get a new title onto Google Play or the App Store. But publishing the exact same game the seller built is not enough: store reviewers, players and even your own ad revenue all reward games that look and feel new. That is what a reskin does.

This guide walks through the whole process, from opening the project to uploading your build, in the order we recommend doing it. No advanced coding is needed for most steps.

What Is a Reskin?

A reskin keeps the gameplay and code of an existing game and replaces everything the player sees and hears: characters, backgrounds, UI, icons, sounds, the name and the store listing. Done well, a reskin feels like a completely different game while saving you months of development.

A good reskin usually changes:

Art: characters, objects, backgrounds and effects
UI: buttons, menus, fonts and colors
Audio: music and sound effects
Identity: game name, icon, package name and store listing
Balance: level difficulty, rewards and pacing

Step 1: Open the Project in the Right Unity Version

Before changing anything, check which Unity version the project was built with. You will find it on the product page, in the seller's documentation, or in ProjectSettings/ProjectVersion.txt inside the project folder.

Install that exact version through Unity Hub and open the project with it. Opening an older project in a much newer Unity version can break render pipelines, UI layouts and third-party packages. If you want to upgrade later, do it only after your reskin is working and backed up.

Tip: put the project under version control (Git or Unity Version Control) before your first change. If a replacement breaks something, you can always go back.

Step 2: Replace the Art

This is the biggest part of any reskin. The safest approach is to replace image files without changing their names, so every prefab and scene that uses them updates automatically.

How to replace sprites and textures safely

Find the original image in the Project window and note its size and import settings (Sprite mode, Pixels Per Unit, compression).
Create your new image at the same size and aspect ratio.
Overwrite the file on disk with the same file name, or drag it into Unity over the original.
Check that the import settings stayed the same, then press Play and look for anything stretched or misaligned.

For 3D games, swap the materials and textures on existing models first. Replacing models completely is possible, but check that the new model has the same pivot, scale and animation rig, otherwise colliders and animations may stop lining up.

Step 3: Restyle the UI

Open each menu scene or UI prefab and update:

Button and panel sprites
Fonts (TextMeshPro needs a new font asset generated from your font file)
Colors, so the whole game follows one new palette
Any text that mentions the original game's name

Test the UI at different screen sizes using the Game view's aspect ratio dropdown. Phones range from short 16:9 screens to very tall ones, and a UI that only fits one of them will look broken on the rest.

Step 4: Change Sounds and Music

Replace audio clips the same way you replaced images: keep the file names so existing references keep working. Use music and sound effects you have the rights to publish, such as royalty-free libraries with a commercial license or tracks you commissioned.

Step 5: Give the Game Its Own Identity

Open Edit > Project Settings > Player and update:

Company Name and Product Name (the name shown under the icon)
Default Icon and the adaptive icon layers for Android
Package Name / Bundle Identifier, for example com.yourstudio.yourgame
Version and Bundle Version Code

The package name must be unique and can never be changed after you publish. Never keep the original seller's package name.

Step 6: Add Your Own Ad and Analytics IDs

Most ready-made games ship with ad integration already in place, but the IDs inside belong to the seller or are test IDs. Before you publish, replace them with your own:

Create your app in your ad network's dashboard (for example AdMob or LevelPlay).
Create the ad units the game uses: banner, interstitial or rewarded.
Put your App ID into the ad SDK's settings in Unity, and your ad unit IDs wherever the game's ad manager script expects them.
Keep test ads enabled while you test, and switch to live ads only for the release build.

Clicking your own live ads can get your ad account banned, so always test with test ads or registered test devices.

Step 7: Tune the Gameplay

A reskin does not have to stop at visuals. Small changes to balance make a big difference to how original the game feels:

Reorder or redesign the first few levels
Adjust speed, difficulty and timers
Change rewards, coin amounts and shop prices

Many templates keep these values in ScriptableObjects or a single config script, which makes balancing easy without touching the gameplay code.

Step 8: Build and Test

For Google Play, build an Android App Bundle (AAB) with a 64-bit (ARM64) target, and set the target API level to the one Google Play currently requires for new apps. Create your own keystore to sign the build and store it safely, because you will need the same keystore for every future update.

Before uploading, test on at least one real device:

Play through the first levels and the main menus
Check that ads load (with test ads)
Rotate the screen and try different phones if you can
Watch for crashes when the game starts and when an ad closes

Step 9: Prepare the Store Listing

Your store page is part of the reskin too. Write your own description, record new screenshots and a short gameplay video from your version, and choose a category and keywords that match how players search for this type of game.

Choosing a Game That Is Easy to Reskin

Some projects are much easier to reskin than others. Before you buy, look for:

A clear Unity version and recent updates
A test APK or WebGL demo, so you can try the game first
Clean folders with art, audio and scripts kept separate
Gameplay values kept in config files instead of hardcoded in many scripts
Ads already integrated with a current SDK

Hyper casual and puzzle games are usually the quickest to reskin because their art is simple and their levels are data-driven. Browse our hyper casual games and puzzle games to find a starting point, or see all ready-made Unity games.
