Hole.io Style Swallow Arena Online

A timed swallow arena in your browser: grow by gulping anything smaller than your hole, and finish as the biggest when the clock hits zero.

Swallow Arena is a hole.io-style free-for-all on a small city map. You are a hole. Cones, benches, cars and buildings fall in when they are smaller than you, and each gulp makes the hole wider. A rival hole only goes down when it is clearly smaller and mostly inside yours — two holes of the same size bounce apart. The round lasts two minutes. When the clock hits zero, the biggest hole wins, and the live leaderboard shows size the whole way. The city keeps four rival holes in the match even if you are playing alone, so vs Computer is a full arena rather than an empty lot. Online, share a five-character room code; Local vs puts two people on one keyboard (WASD and the arrows). Physics run on the server. Your own hole predicts ahead of the next snapshot so steering stays smooth, and everyone else is interpolated. On a desktop, move the mouse or hold WASD / the arrows. On a phone or tablet, drag one finger on the map or use the on-screen stick, in portrait or landscape. Easy computer holes wander after nearby snacks. Hard holes hunt smaller rivals and dodge anything that can swallow them. Free in the browser — no download, no account.

How to play Swallow Arena

Swallow Arena is a free hole.io-style game. Each player is a hole on a city map. Anything smaller than you — cones, benches, cars, then whole buildings — tips in and makes you bigger. A two-minute clock decides it: the biggest hole at the end wins.

Rules

Your hole moves continuously. An object falls in when it is smaller than you and its center is inside the hole. You grow a little with every gulp, and bigger holes move a bit slower. Another hole is swallowed only when it is clearly smaller (about three quarters of your size or less) and mostly inside you. Similar-sized holes shove apart instead of eating each other. If you are swallowed, you drop back in a couple of seconds at starting size — your rival keeps the mass. City bots fill the spare seats so the map is never empty. When the timer ends, the largest hole wins. Ties go to the higher score.

Controls

Desktop: move the mouse, or hold WASD or the arrow keys. Phone and tablet: drag one finger on the map, or use the stick. Local vs: player 1 uses WASD, player 2 the arrow keys, each with a stick. Let go and the hole coasts to a stop.

Tips

Clear cones and benches first, then cars, and only then the buildings. Do not sit next to a hole that is already wider than you — back off and eat until the gap is obvious. The leaderboard is live, so a late growth spurt can still take the round.

Swallow Arena FAQ

Is this the official hole.io game?

No. Swallow Arena is an original hole.io-style game made for this site, played in the browser with friends or against computer holes.

Can I play a hole.io style game online with a friend?

Yes. Create a room, share the code, and both of you drop into the same city. Other people can watch, and you can rejoin if you drop out.

What if I am playing alone?

Choose vs Computer. You still share the map with rival holes, including four city bots, so there is always something to chase and something to dodge.

How do I win?

Be the biggest hole when the two-minute timer ends. Swallowing a clearly smaller rival hole is allowed; a hole close to your size is not.
