Games Like Agar.io: 8 Free Browser Picks for 2026

What makes a game "like Agar.io"

Agar.io turned a simple rule into one of the most-played browser games ever: eat what is smaller than you, run from what is bigger. Every game on this page keeps that rule. The fun is in what each one adds on top, like tunnels, territory, weapons or a closing storm.

We make Orb Arena, so it's on this list, and we've said so up front. The other picks are games we'd honestly recommend. Each one gets a line on what it does better than the original and where it falls short.

Quick picks

• Closest to the original: Senpa.io, which keeps split, feed and merge and adds clans and events.
• Best twist on the formula: Digdig.io, where you dig through the map to ambush and escape.
• Best for short sessions: Orb Arena, where a shrinking Storm ring ends every three-minute round.
• Best for strategy fans: Territorial.io.
• Best land-grab alternative: Paper.io 2.

The list

Senpa.io. If you want classic Agar.io with more around it, start here. Splitting, feeding and merging work the way veterans expect, and there are clans, seasonal events and several server modes. The downside is that it's busy. New players can feel lost among the menus and modes.

Digdig.io. It comes from the studio behind Agar.io and adds terrain you can dig through. Tunnels become cover, ambush routes and escape hatches. It keeps the eat-and-grow tension but makes position matter far more than in an open arena.

Diep.io. It swaps blobs for tanks and adds upgrade trees. You still grow by farming shapes and other players, but each upgrade choice changes how you play. It's the pick for anyone who wants builds and classes on top of growth.

Orb Arena. Our game. You eat glowing orbs, grow, split to hunt and avoid bigger rivals. You play against ten computer-controlled rival orbs rather than other people, so there's never a wait for a server or lobby. The difference is a Storm ring that tightens every 30 seconds, so nobody can sit in a corner and farm forever. Rounds last three minutes and end in a final showdown rather than fizzling out. There's also a Daily Challenge with XP streaks, plus skins and trails you unlock free with XP. It runs in any modern browser with no download.

Paper.io 2. Instead of eating, you claim ground by drawing loops back to your own area. One cut across your trail ends your run. It's a different skill from Agar.io, but the same thrill of one mistake costing everything.

Splix.io. The grid-based original of land-capture .io games. It's simpler and faster than Paper.io 2, with fewer visual extras.

EvoWars.io. Growing makes your warrior bigger and their sword longer, but slower. That's the same trade-off as Agar.io's mass and speed, turned into melee fights.

Territorial.io. This one is a slow-burn strategy game. Hundreds of players expand across one map by budgeting attacks and making truces. Play it when you want to think, not dodge.

Comparison table

How to pick

If you miss the 2015 feeling, play Senpa.io. If you only have five minutes between classes or meetings, a game with a built-in end like Orb Arena suits you better than an open-ended arena. If you want to plan rather than react, try Territorial.io. Most of these load in seconds, so the honest advice is to try three and keep the one that makes you say "one more round."
