Onion Boy

About Onion Boy

Onion Boy is one of those deceptively simple platformers that hooks you the second you press the jump button. You play as a plucky little onion — yes, an onion — sprinting and leaping through a colorful world of spikes, gaps, and floating platforms. The premise is delightfully weird, but the gameplay is razor-sharp: tight controls, pixel-perfect jumps, and levels that punish careless mistakes while rewarding patience and precision.

It's a favorite on unblocked games 67 because it loads instantly, runs on almost any school Chromebook, and doesn't need a download or login. Whether you're sneaking in a quick run between classes or grinding for a high score at home, Onion Boy delivers that classic "just one more try" energy that keeps players coming back. If you grew up on retro platformers, this one will feel instantly familiar — just with more crying vegetables.

How to Play & Controls

Your goal is straightforward: guide Onion Boy from the start of each level to the exit flag without getting skewered, squashed, or dropped into the void. Along the way you'll collect coins and gems that boost your score, and dodging hazards cleanly often unlocks bonus points.

Movement is simple but demands timing. You run left and right, jump over obstacles, and land on moving or disappearing platforms. Some levels throw in enemies that patrol back and forth — stomp them from above or avoid them entirely.

• Desktop: Use the Arrow Keys or WASD to move. Press Space or the Up Arrow to jump.
• Mobile: Tap the on-screen left/right buttons to move and the jump button to leap. The touch controls are responsive, so no extra app is needed.
• Objective: Reach the flag at the end of each stage while grabbing as many collectibles as possible.

Pro Tips & Strategies

Want to actually finish those brutal later levels? Here's how to sharpen your game:

• Master short hops: Tapping jump briefly gives you a smaller leap. Use short hops for tight gaps and full jumps only when you need maximum height or distance.
• Look before you leap: Many deaths come from jumping too early. Pause at the edge of a platform, read the pattern of moving hazards, then commit.
• Grab coins on the way, not on a detour: Chasing every collectible can cost you a life. Prioritize survival first, then sweep up coins on a second, safer run.
