Hexanaut.io is a territory IO game built on a hexagonal grid, developed by Exodragon Games and playable free in any browser. The goal is to capture hexagonal tiles by looping your tail around them, reach 20% of the map to claim the Hexanaut title, then hold that lead for two consecutive minutes to win. It sounds straightforward. It isn't. Between the totem system, the real-player competition, and the permanent death risk that kicks in once someone else holds the title, there's more going on here than Paper.io ever managed.
What Is It?
Exodragon Games launched Hexanaut.io in beta in January 2022 and has updated it consistently since — new skins arrived as recently as October 2025, a weekly rotating game mode launched in May 2025, and custom colour settings dropped in March 2026. This is an actively maintained game, not an abandoned flash relic.
The hex grid is the key differentiator. Where Paper.io and Splix.io use square grids that create predictable right-angle capture patterns, Hexanaut's hexagonal tiles allow six directional movement paths. That changes the geometry of every capture decision — the same "surround and close" tactic that works in Paper.io needs recalibrating here, and that recalibration is half the fun.
The game is free, browser-native, and requires no account to play — though creating one unlocks a full ranking system (Copper through Grandmaster), persistent stats, and the cosmetics progression. On Coolmath Games, it's listed without the account requirement as a first-session barrier, making it genuinely accessible as a pick-up game.
Gameplay
Controls are mouse-only. Your avatar follows your cursor. Leaving your territory extends your tail — the line behind you that's vulnerable to being cut. When you return and close the loop, every tile inside the loop becomes yours. The core tension: the further you reach from home territory, the longer your exposed tail, and the longer an opponent has to kill your run by cutting through it.
Five totems are scattered across the map, each capturable by reaching them and closing territory around them. The spreading totem auto-captures adjacent tiles passively — essential in the early game when you're building from scratch. The speed totem grants a 5% movement boost per pickup, compounding significantly if you stack several. The teleportation gate lets you instantly warp back to base after a deep-territory raid, eliminating the vulnerable tail-drag home. The slowing totem creates a speed debuff zone around opponents — genuinely oppressive when deployed in contested space. The spy dish reveals all enemy territory positions on the minimap. Prioritise speed totems early, spy dish and teleportation once you're established.
Match pacing is well-structured. Early minutes are relatively safe expansion into unclaimed ground. Mid-game gets aggressive as the map fills. Late game — once someone hits 20% and becomes the Hexanaut — shifts into a siege dynamic where the Hexanaut defends while everyone else hunts them. If you're eliminated while another player holds the Hexanaut position, you can't rejoin. That one rule adds real stakes to every move once the title is in play.
On the bot question: Hexanaut.io uses bots to fill lobbies during low-traffic hours. Coolmath Games confirms this openly. The bots behave differently from real players — more predictable paths, less aggressive tail-cutting — so you'll notice when peak hours end. During school hours and evenings (US/EU time), lobbies fill with real players quickly enough that the bots are a brief opening-session experience, not the norm.
Pros
- Hex grid creates genuinely different geometry from square-grid competitors
- Five-totem system adds strategic depth that most IO games skip entirely
- Active development — skins, new modes, and updates through 2026
- Full ranking system (Copper to Grandmaster) rewards long-term play
- Mouse-only controls work well on both desktop and touchpad
- No download, no account required to start playing
- Distinct win condition (hold 20% for 2 minutes) gives matches a structure most IO games lack
Cons
- Lobbies are padded with bots during off-peak hours — behaviour is noticeably less dynamic
- Permanent death mechanic (can't rejoin while another player is Hexanaut) punishes mid-game mistakes harshly
- Mobile app version (Google Play) is a different game entirely — stick to browser
- Early-game without spread totem can feel slow
- Visual feedback when your tail is cut is abrupt — new players won't always know what killed them
Tips & Tricks
- Grab the spreading totem first, every time. It passively captures adjacent tiles while you focus on larger loops. In the early game when you have almost no territory, this is the fastest way to build a safe base.
- Stack speed totems before going aggressive. Each one adds 5% movement. Two or three stacked gives you enough pace to close loops and escape tail-threats that would catch you at base speed.
- Close small loops, not big ones. The temptation is to swing wide and capture a huge chunk. The risk: more tail exposure, more time for opponents to cut you. Ten small loops are safer than one large one.
- Use the teleportation gate immediately after a deep raid. Don't drag your tail home across enemy territory. Capture the gate first, raid second, teleport home third. Eliminates the most dangerous part of any offensive move.
- Play the perimeter of your territory, not the centre. Patrolling your own borders lets you cut tails of opponents trying to claim your tiles. Mid-territory movement accomplishes nothing defensively.
- Deny the Hexanaut's territory, don't just expand your own. Once someone hits 20%, the collective goal shifts. Chipping into the Hexanaut's tiles — even small bites — drops their percentage and resets their two-minute clock.
- Watch the minimap constantly once the spy dish is on the map. If you can see everyone's positions, you can pick safe expansion directions. If you can't, assume you're being watched and close your loops quickly.
Hexanaut.io vs Paper.io 2
The most common comparison. Both are territory IO games, both are free browser games. Hexanaut wins on strategic depth — the totem system, the win condition, and the hex geometry all add layers Paper.io doesn't have. Paper.io has a larger player base and snappier early-game feedback. If you want to learn the genre, Paper.io is easier. If you want the better game, it's Hexanaut by a clear margin.
Hexanaut.io is the best territory IO game in the browser right now — and almost nobody outside of Coolmath's audience knows it exists. The hex grid, the totem system, and the Hexanaut win condition turn what could be a basic land-grab clone into something with actual strategic texture. The bot problem is real during quiet hours, but peak-time lobbies are competitive and the ranking system keeps experienced players pushing.
FAQ
Is Hexanaut.io free?
Yes, completely free. No account required to play. Creating an account unlocks the ranking system, persistent stats, and cosmetics, but none of it affects gameplay or is required to start.
How do you win Hexanaut.io?
Capture 20% of the map to become the Hexanaut, then hold that percentage for two consecutive minutes without being eliminated. Other players will actively try to chip your territory below 20% to reset the clock.
Are the players in Hexanaut.io real?
Mostly. During peak hours (school hours and evenings, US/EU time), lobbies fill with real players. During off-peak hours, bots fill gaps. Coolmath Games confirms this openly — bots exit as real players join.
What are the totems in Hexanaut.io?
Five capturable power-ups: spreading totem (auto-captures adjacent tiles), speed totem (+5% movement per pickup), teleportation gate (instant warp to base), slowing totem (debuffs nearby opponents), spy dish (reveals all enemy positions on minimap).
How do you become the Hexanaut?
Capture and hold 20% of the map. You don't have to capture it all at once — gradual expansion works. Once you hit 20%, you become the Hexanaut and the two-minute countdown starts.
Is Hexanaut.io better than Paper.io?
For strategic depth, yes. The hex grid changes capture geometry, the totem system adds objective play, and the distinct win condition gives matches structure. Paper.io is simpler and has a larger player base. Hexanaut is the better game.
What happens when you get eliminated as Hexanaut?
You lose your position and the title transfers to the next player above 20%. If another player is currently Hexanaut and you get eliminated, you can't rejoin that match — a mechanic that adds real stakes to every move late-game.
