87bd is a fast-paced digging arcade adventure for mobile. Tap Dig to descend deeper underground, collect gold coins and precious gems, dodge random rock blocks, and chase the highest depth score in every run.
The app opens with a splash screen and loading indicator, then shows a sticky header, quick menu, and decorative banner optimized for portrait play.
The navigation menu includes Play, About, Rules, and Rewards. The core game displays a vertical mine shaft with a digger icon. Each Dig tap moves you one level deeper. Gold awards bonus points, gems award higher scores, and rocks end the current run.
Live stats track depth in meters, total score, and gems collected. When a rock blocks your path, a summary screen shows your final depth and score. Restart instantly to beat your best dig.
About explains the digging adventure concept with a feature illustration. Rules cover the Dig button, treasure values, rock penalties, and depth records.
Rewards includes a rank system: Master Digger for depth 50 meters or more, Gold Hunter for 500 or more points, Gem Collector for 10 or more gems, and New Prospector for other results.
87bd combines tap-driven arcade gameplay, rising depth challenge, and a warm gold and brown visual style in one compact treasure-themed app.
