About Diamond Rush

Diamond Rush is one of the most beloved mobile games of the mid-2000s. Released by Gameloft in late 2006 for Java ME (J2ME) feature phones, it became an instant sensation on Nokia, Sony Ericsson, and Samsung handsets worldwide. For an entire generation of mobile gamers, it delivered a full-scale archaeological adventure on a pocket-sized screen.

Taking inspiration from classic 1984 Boulder Dash mechanics, Diamond Rush casts you as a daring explorer sporting a beige fedora and explorer jacket. Your quest begins when you discover an ancient stone seal missing three legendary gemstones. To unlock its secret, you must journey through 40 dangerous stages spanning three distinct ancient civilizations:

  • Angkor Wat: Deep within the Cambodian jungles, uncover the Fire Diamond while avoiding poison darts, snapping snakes, and collapsing stone ruins.
  • Bavaria: Navigate castle dungeons, heavy iron gates, and treacherous water-flooding chambers to recover the Silver Diamond.
  • Tibet: Scale frozen monasteries and cavernous ice chambers filled with falling stalactites, slippery slopes, and mythical guardians to retrieve the Ice Diamond.

A Pure JavaScript Preservation Breakthrough

When the feature phone era came to an end, thousands of classic J2ME titles became unplayable on modern hardware. This edition on Quenq is a true technical triumph: rather than relying on clunky third-party app emulators or Java plugin installations, it is a standalone, pure JavaScript implementation of the game.

All original game assets, levels, bytecode logic, and authentic Nokia MobileBAE sound synthesis are executed natively in your browser with zero latency and full offline capability.

Dual Display Modes: Portrait & Landscape

Back in the 2000s, mobile phones came with diverse screen orientations. This web edition faithfully supports both formats with automatic responsive scaling:

  • Widescreen Landscape (320x240): Provides a broader horizontal field of view across puzzle rooms. Ideal for desktop displays and horizontal gameplay.
  • Classic Retro Portrait (240x320): Recreates the authentic tall vertical display of classic Nokia phones, automatically arranging the game canvas with virtual keypad and softkeys below when held vertically.
  • Dynamic Responsive Scaling: The viewport automatically scales to fit your display perfectly, keeping the pixel art crisp and controls natural on any phone, tablet, or PC.

Game Controls & Cheats

  • Movement: Use Arrow Keys (↑, ↓, ←, →) to move the explorer, or use the on-screen virtual D-pad on touch devices.
  • Action / Confirm: Press Space or Enter on keyboard, or tap the OK action button on touchscreens.
  • Softkeys: Press Q (Soft Left) and W (Soft Right) for menu interactions and dialog prompts.
  • Numpad & Cheats: Press keys 0 through 9, E for *, and R for #. You can also tap the # button on the top-left to toggle the virtual numpad.
  • Toggle Numpad: Press Esc to quickly show or hide the on-screen numpad.
  • Secret Level Skip: In-game, press 9 to skip the current level instantly, or press # to toggle level skipping.
  • Fullscreen: Press F on keyboard or click the Fullscreen button in the player controls.

Treasure Hunting Tips

  • Mind the Boulders: Never dig directly beneath a stack of boulders without an exit route. A falling boulder will crush your explorer instantly.
  • Collect Every Red Diamond: While purple diamonds increase your score, rare red diamonds are required to unlock secret chambers and access subsequent worlds.
  • Use Boulders to Block Hazards: Heavy gray rocks can be pushed onto fire spouts and geysers to create safe pathways across otherwise impassable pits.
  • Persistent Saves: Your cleared worlds, diamond totals, and mission checkpoints save automatically to your browser storage (localStorage).
