TetraMain

TetraMain - Play Online

TetraMain is pure Tetris with a blocky twist. Instead of boring geometric shapes, you're stacking Minecraft-style ore blocks—Redstone, Diamond, Iron, and Gold—to clear lines and rack up points. It's the classic falling-block puzzle you know, but dressed in pixel-perfect resource textures. Perfect for quick brain workouts between tasks.

Key Features

• Classic Tetris Mechanics: Rotate, move, and drop falling blocks to complete horizontal lines. No gimmicks, just pure puzzle skill.
• Pixel-Perfect Ore Textures: Clean 2D visuals featuring iconic Minecraft-style blocks like Diamond, Gold, and Redstone. Retro aesthetic meets instant nostalgia.
• Unlock New Worlds: Progress through different levels with unique block textures. The more lines you clear, the more ore varieties you discover.
• Endless Mode: No time limits. Play at your own pace or challenge yourself to beat your high score. The game only ends when the well fills up.

How to Play TetraMain

Easy to start, impossible to stop. The first few levels teach you the rhythm—then the speed kicks in.

Controls

Responsive on both desktop and mobile. Zero lag.

• Desktop: W or ↑ to rotate blocks. A/← and D/→ to slide left or right. S/↓ for fast drop. Spacebar for instant fall. P to pause.
• Mobile: Tap the screen to rotate. Swipe left or right to move blocks. Hold your finger at the bottom for accelerated drop.

Stacking Your Ore Blocks

Blocks fall from the top one at a time. You see the next piece in the preview box. Use rotation and horizontal movement to fit each block into gaps. Think one move ahead—Redstone and Diamond blocks don't care about your mistakes.

Clearing Lines for Points

Complete a full horizontal row with no gaps, and it vanishes. Score increases with each line. Clear multiple lines at once for bonus points. The challenge? Blocks fall faster as your level rises. Hesitate and the well fills. Game over.

Unlocking New Worlds

Hit score milestones to unlock new texture sets. Start with basic Coal and Redstone. Progress to Iron, Gold, Lapis, and Diamond ore. Each world keeps the same mechanics but rewards your eyes with fresh block skins. Higher levels mean faster drops and tighter margins for error.

Who is TetraMain for?

Office workers hunting for a 5-minute brain break. Puzzle fans who want Tetris without the bloat. Minecraft lovers who need a chill falling-block fix. Sessions last as long as you survive—could be 2 minutes or 20.

The Gameplay Vibe

Meditative chaos. The first 10 lines feel zen—you're just sliding blocks into place, watching rows vanish. Then the speed ramps up. Suddenly you're in the zone, fingers tapping W-A-D on autopilot, chasing that high score. The blocky textures and smooth 60 FPS keep your eyes locked in. No distractions, no fluff. Just you versus gravity.
