icon](https://bestforandroid.com/apk/wp-content/uploads/2026/05/icon277.png)Hailey’s *Treasure* Adventure Version **0.7.3.9** · LAGS · `com.LAGS.HaileysAdventure` A 2D mining and puzzle-platformer from indie studio LAGS, where you dig through 20 hand-built mine levels, collect gems and ore, and rescue characters across a layered treasure hunt. This page hosts the unlocked mod build. Version 0.7.3.9 Size 243 MB [Android](https://bestforandroid.com/ "best android guides") 6.0+ Rating 18+ What is *Hailey’s Treasure Adventure* ------------------------------------- Hailey’s Treasure Adventure is a 2D side-scrolling platformer built around mining, exploration, and timed objectives. You guide Hailey through a series of mines, breaking blocks with a pickaxe, planting bombs to clear paths, and collecting diamonds, gold, and ore. The resources you gather feed an upgrade loop that raises health, stamina, and gear so deeper levels stay survivable. The game leans on light combat and puzzle-solving rather than fast reflexes. Each mine introduces new layouts, hazards, and enemy mixes, and progress unlocks side content such as the Annie Expedition and bonus stages. It is a mature title aimed at adult players, and the build hosted here is the modded version with progression perks already applied. LAGS is a small independent developer, and the game is delivered as a single Android package rather than a store install. Because it sits outside the usual store channel, sideloading the [APK](https://bestforandroid.com/apk/ "apps apk download") is the standard way to run it on a phone or tablet. A look at *the mines* --------------------- ![Hailey's Treasure Adventure pixel mining gameplay](https://bestforandroid.com/apk/wp-content/uploads/2026/05/icon277.png) Pixel-styled mine levels mix digging, resource collection, and light combat. No official store screenshots are published for this title, so the brand mark stands in above. What this *mod* offers ---------------------- - **Unlimited money and gems**The in-game currency pools start topped up, so upgrades and gear are available without grinding ore runs first. - **Unlocked upgrades**Health, stamina, and pickaxe tiers can be raised early instead of being gated behind long resource collection. - **All 20 mine levels accessible**Level gates that normally open through progression are available from the start for free exploration. - **Bonus side content unlocked**The Annie Expedition and bonus quests added in later builds are reachable without finishing the main story first. - **No store dependency**The build runs as a standalone APK, so it installs and updates outside any app store account. How to *install* ---------------- 1. **Download the APK file**Tap the download button on this page. The file lands in your default Downloads folder. 2. **Allow installs from this source**Open Settings, search for `Install unknown apps`, find your browser or file manager, and turn the permission on. 3. **Open the downloaded APK**Tap the file in Downloads. The Android package installer opens and lists the permissions the game requests. 4. **Tap install**Confirm the install and wait for the progress bar to finish. The download is around 243 MB, so allow a little time on slower connections. 5. **Launch and play**Open the game from your app drawer. The mod perks are active on first run, so currency and unlocks are ready in the first mine.
