Ruby Raid drops you into a temple escape that never lets up. You've stolen the Eye God's sacred ruby, and now a massive laser beam chases you relentlessly through side-scrolling terrain packed with blocks, barriers, gaps, and hostile worshippers.

Your character runs forward automatically at a steady pace, so the entire challenge comes down to two actions: jumping obstacles and shooting threats. That simplicity is what makes the game so immediately engaging — you're in the action within seconds.

The depth comes from the weapon progression system. Gems collected during each run are spent on unlocking new guns from a pool of over 25 weapons, each with different firepower, range, and shot patterns.

Stronger weapons let you clear enemy waves faster, which is essential as later runs pack tighter obstacle sequences and denser crowds of Eye God worshippers into shorter distances.

The quick-restart loop means every failed attempt feeds directly into your next, better-equipped run. Ruby Raid uses a minimal two-button control scheme. On desktop, press the Left Arrow Key to jump over gaps, blocks, and environmental hazards.

Press the Right Arrow Key to fire your equipped weapon at enemies ahead. On mobile and tablet, tap the left side of the screen to jump and the right side to shoot — or use the on-screen buttons provided.

Your goal is to survive the laser chase and reach the target distance for each run. Your character runs forward automatically at a constant speed. If you stop moving — by hitting a wall or getting stuck on an obstacle — the laser closes in and kills you instantly.

Each run has a distance target, and reaching it completes that stage and unlocks harder terrain. Gems collected along the way carry over between runs. The temple route is filled with two categories of threats: environmental hazards and hostile NPCs.

Environmental hazards include gaps in the ground, raised blocks, moving barriers, and trap sequences that require precisely timed jumps. Enemy worshippers and temple defenders stand in your path and must be shot before they block your momentum.

Getting hit by an enemy or colliding with an obstacle costs you time and distance, letting the laser catch up. Gems are the primary currency in Ruby Raid. After each run, you can spend collected gems in the weapon shop to unlock new guns.
