Onion

Onion swaps the usual match-and-clear formula for something more tactile. You start with a bulbous, multi-layered sphere and work inward, stripping away outer coats to expose the compact center. The catch is that each layer alters what you can reach, so a casual swipe can leave you stuck. It is a slow-burn brain teaser that rewards patience and planning over twitch reflexes, yet it never feels sluggish thanks to snappy, responsive controls. As you progress, the patterns on each layer grow more intricate, hinting at the structure below. Careful observation turns every session into a mini-quest of deduction and precision. With a clean, minimal aesthetic and a gentle learning curve, it is easy to drop in for a few minutes or settle in for a longer stretch. There is no clutter, no timers, and no pressure—just you, the layers, and that satisfying moment when the core finally comes into view.

What is Onion

Onion is a thoughtful arcade puzzle where you carefully remove outer layers to reveal the inner core. It is a game of foresight and subtle strategy.

How to Play

Tap or click on the outer layer you wish to remove, peeling it away to expose the next one. Continue peeling strategically until the final core is revealed.

Tips for Playing

Study the layer patterns before peeling; they often hint at the core's position.
Peel symmetrically to keep the structure balanced and avoid trapping yourself.
Don't rush—plan a couple of moves ahead to avoid blocking key paths.
If you get stuck, take a break and return with fresh eyes; the solution is often simpler than it seems.
Try different peeling orders in the same level to discover efficient routes.
