The short answer
Asteroid Duel is a free space duel for two players on one phone, or on two phones over the same Wi-Fi, with fifty levels and ten bosses for one player. It runs on iPhone, iPad and Android with no account. Its coins are earned by playing and spent on your ship; you can't buy them and they never turn into money.
About Asteroid Duel
Asteroid Duel puts a ship at each end of the screen with a field of drifting asteroids between them. Blast the rocks for points, blast the other ship to take its hull down, and whoever is ahead when the clock runs out wins, unless somebody is destroyed first, which ends it on the spot. You can play it in this browser before installing anything, two of you on one keyboard if you like — everything but Nearby, which pairs two phones over Wi-Fi and needs a socket a tab may not open.
There is no fire button, on purpose. A thumb can only do one job at a time, so the trigger is automatic and steering is the whole of what you do. Where to point is the decision that matters, and handing it the whole thumb keeps a duel readable with two people playing on one phone.
Two people on one phone is the main event. Each player gets their own half of the screen to steer on, and the two ships face each other along whichever edge is longer, so it works held upright or sideways. Play a single round or a first-to-three; the score carries between rounds and the app remembers your head to head, so there is always something riding on the next one. If one of you is older, the other can be given a head start, which is a setting the two of you agree on; the game does not decide it. A level match never ends in a draw — the next point settles it. On the same Wi-Fi you can use two devices instead: one player hosts, the other types the number from their screen, and you each get a full display to fly on. There is no sign-in, no friend list and no lobby of strangers, and the game does not even send a device name.
The duel is not the only thing two people can play. Tug-of-war puts one big rock in the middle, and every shot that lands shoves it toward the other player; you win by pushing it past their line. Hot potato arms a mine with a countdown you can see, and shooting it sends it to their side, with the fuse shortening every crossing. Co-op turns the field against both of you, with one shared hull and waves that keep coming. For a group there is a bracket: pass the phone round, and eight people play seven duels rather than the twenty-eight a round robin would take.
Alone, there is a fifty-rung campaign with a boss on every fifth, flown against five pilots — Rookie, Cadet, Pilot, Captain and Ace. Every one of them flies the same ship you do, with the same cooldown and the same hull. They do not cheat. They are better pilots. Each level is scored out of three stars: one for the win, two for ending it by destroying them, and three for doing that without being touched. Endless sends pilot after pilot until you go down, and Practice has no clock, no score and nothing that can hurt you, for anyone still learning to steer. One duel a day gives everybody the same asteroid field and the same pilot, with a streak to keep.
Asteroid Duel has coins, as several of our games do, so here is what they are. Coins are earned by playing and spent in the hangar on hull plating, cooling, engines, bolt charge and paint. They cannot be bought with money — there are no in-app purchases of any kind in this game — they convert to nothing, and they are worth nothing outside the app. They are not the coins in our reward apps, which are worth a tenth of a cent each and come out as PayPal cash. The bot buys the same list at the same prices, so you can always read what you are up against. None of it reaches a two-player duel either, where the two ships are always identical whatever either of you has bought.
Crates are contested rather than collected. Shoot one to claim it: rapid fire, a triple shot, piercing bolts, overdrive, or a shield that stops the next hit dead. Chasing one costs you shots you were not aiming at your rival, because it is just as shootable by them as by you. The game is free and paid for by two ads: a small banner on the menus, and a full-screen ad between rounds after every fourth finished match. There is never an ad over the playfield while you are flying, and never one in the middle of a duel. Scores, coins and badges stay on the device, and there is no account.
There are free Asteroid Duel coloring pages to print, drawn from the game's own art. There are mazes and drawing pages from it too.

Frequently asked questions
Does Asteroid Duel pay me anything?
No. The coins in it are not money and never become money: you earn them by playing, you spend them in the hangar on your ship, and they convert to nothing and are worth nothing outside the app. That's the opposite of the coins in our reward apps, which are worth a tenth of a cent each and come out as PayPal cash. We're spelling it out because a site that spends its time asking other companies what their currency is worth doesn't get to be vague about its own.
Is it free? What is the catch?
It's free and there are no in-app purchases of any kind — you cannot buy coins, ships, upgrades or anything else. The catch, such as it is, is the advertising: a small banner on the menus, and a full-screen ad between rounds after every fourth finished match. There's never an ad over the playfield while you're flying, and never one in the middle of a duel.
What do I need to run it?
An iPhone or iPad on iOS 15.0 or later, or an Android phone or tablet, and a second person if you want the part the game is built around. Two devices need to be on the same Wi-Fi to play across them.
Do the upgrades make it unfair?
Not against another person, which is the case that matters. None of what you buy in the hangar reaches a two-player duel: those two ships are always identical, whatever either of you has spent. Upgrades apply on the pilot ladder, and the bot buys the same list at the same prices, so what you're up against is always readable. If you want to even out a duel between players of different ages, the head start is the setting for that, and the two of you agree it.
Can two people play on one phone?
Yes, and that's the main event, not a mode bolted on. Each player steers on their own half of the screen and the two ships face each other along the longer edge, so it works upright or sideways. On the same Wi-Fi you can use two devices instead: one hosts, the other types the number from the host's screen. No accounts, no friend list, no lobby — and the game doesn't send a device name.
Is there an iPhone version?
Yes, since 30 September 2026. It came to the App Store three weeks after Google Play, and it runs on iPad too. That leaves five things we publish that Android has and iPhone does not: four games, Peel Frenzy, Pie Cannon, Broadside and Slap Pile, and one tool, Dead Center.
Is it suitable for children?
Google Play rates it Everyone with a Mild Fantasy Violence descriptor, which here refers to shooting a spaceship. The App Store rates it 9+ for infrequent cartoon or fantasy violence and guns or other weapons, which is the same spaceship read more strictly. On Play it's one of four things we publish carrying a content descriptor at all; the others are Pie Cannon, for throwing a pie at a wooden duck, Broadside, for cannon fire at sea monsters, and Card Lab, rated Everyone with Violent References. There's nothing to buy, so nothing a child can spend money on. It does carry advertising, including a full-screen ad between rounds after every fourth match, and that's the thing worth knowing before handing a phone over.
Do my coins and badges follow me to a new phone?
No. Scores, coins and badges stay on the device, and there's no account to sign into, so there's nothing to sync. Since the coins are worth nothing outside the game, there's also nothing at stake in that beyond the ship you'd built.
How does it compare to 2 Player Games?
2 Player Games is a collection of many small games for two, with 424,138 App Store ratings, ads, and a $6.99 Remove Ads purchase. Asteroid Duel is one space duel with several modes around it and no in-app purchases. We compared the two, and five other games two people play on one phone, in games like 2 Player Games, with our interest declared at the top.
