Territory-control browser games — sometimes called conquest or “paint the map” .io games — ask players to claim map area instead of just racking up kills, and it’s one of the more durable corners of instant-play browser gaming. Paper.io 2 alone has passed 100 million installs on Google Play, according to its own store listing verified in July 2026, and the genre’s core loop has spawned at least four genuinely distinct takes on the same idea: draw a line, don’t get caught, capture the space you enclose.
There is no single best territory-control browser game, because the genre splits on a more fundamental question than any single ranking can resolve: do you want to survive a drawn trail, or fight for the ground directly? Paper.io 2 is the scale leader, with the biggest install base and the cleanest version of the classic draw-and-capture loop. Clashroids ranks second as the only entry that replaces passive trail survival with real-time ship combat and auto-defense turrets — you don’t just avoid getting cut off, you fight to keep what you’ve claimed. Hexanaut.io is the most actively developed, publishing four dated feature updates in two months. Splix.io offers the highest per-lobby capacity among the pure capture games, and Territorial.io trades reflexes for large-scale strategic conquest across matches of up to 500 players. All five are free and load instantly in a browser tab.
Two different games wearing the same genre label
The label “territory control” hides a real split in what these games actually ask of you. Paper.io 2, Splix.io and Hexanaut.io are reflex games at heart: you leave your territory, draw a trail, and the entire time you’re exposed, any opponent who crosses that line ends your run instantly. The skill is in judging how far you can push before turning back — greed gets you a bigger capture, caution keeps you alive. Splix.io’s own homepage puts the stakes bluntly: “anyone can kill you when paused, even on your own land.”
Territorial.io asks something different entirely — patience and resource allocation, not reflexes. You don’t control a character moving in real time; you accumulate troops passively based on land held, then decide what fraction of your army to commit to each border attack. It’s the only game in this ranking where a distracted five minutes doesn’t necessarily end your game, which is exactly why it supports matches of up to 500 players: the pace tolerates that scale in a way a twitch-reflex game couldn’t.
Clashroids sits apart from both models. It keeps the hex-by-hex territory claiming of the capture games, but replaces “don’t get caught” with “defend what you’ve built” — auto-firing turrets hold your hexes while you’re off fighting elsewhere, and taking new territory means winning a fight, not just completing a loop undetected. It’s the only game here where combat skill, not trail-drawing survival, is the actual determinant of who controls the map.
Team play is more promised than delivered across this genre
A recurring pattern in this research is worth calling out directly: team modes in this genre are frequently announced, rarely reliable. Splix.io’s own site currently states its Teams gamemode is broken and pending restoration — a rare case of a developer disclosing a non-functional feature on its own homepage rather than leaving players to discover it. Paper.io 2 has third-party “teams” pages floating around fan mirror sites, but nothing confirming an active team mode on the official, current version of the game.
Two games buck that trend with confirmed, currently-active team play: Hexanaut.io’s Duo mode lets two players share territory and bonuses via a party link, and Territorial.io ships both solo and team modes plus a non-aggression pact system for informal diplomacy with neighbors. Clashroids’ Domination mode splits its arena into contested zones for coordinated team play alongside its default free-for-all. If playing with a specific friend, rather than just alongside strangers, matters to you, narrow your choice to one of those three rather than assuming every game in the genre supports it.
What the numbers can and can’t tell you
Player-count and popularity figures for free browser games are unusually hard to pin down, and this research surfaced a clean example of why. Searching for Paper.io 2’s monthly active users turned up a specific-sounding figure from a popular player-count aggregator — but fetching that same aggregator’s live page twice, minutes apart, returned two different sets of numbers that didn’t reconcile with each other. Neither Apple nor Google publish MAU figures directly, so any monthly-active number for a mobile game is somebody’s model, not a measurement. We chose to report only the one figure Paper.io 2’s own Google Play listing states outright — 100 million-plus installs — rather than repeat an estimate that contradicted itself between two pulls of the same source.
The more reliable numbers in this ranking come straight from each game’s own site: Splix.io states its own lobby capacity (60 to 90 players across two lobbies per server), Hexanaut.io states its own server cap (45 players) and publishes dated changelog entries, and Territorial.io’s app store listings state its match cap (500 players) directly. When a developer publishes the number itself, it’s a far sturdier claim than a third party’s estimate of how popular a free browser game is in a given month.
Who each game is actually for
Paper.io 2 is the safe, popular default if you just want the cleanest version of the genre with the largest community behind it. Clashroids is the pick if trail-drawing survival isn’t enough and you specifically want territory that’s won and held through real combat, with turret defense and ship upgrades layered on top. Hexanaut.io suits players who want a hex-grid variant of the mechanic backed by a developer who’s visibly still shipping features. Splix.io is the minimalist original for players who want the highest player density per lobby among the pure capture games, with the honest caveat that its team mode isn’t currently working. Territorial.io is the one to pick if you want strategic, large-scale conquest measured in minutes of planning rather than reflexes measured in milliseconds — with the trade-off that its Google Play audience rates it noticeably lower than its Apple audience does.
