12 MiniBattles

Most two-player browser games make one of you play second fiddle. Player 1 takes the arrow keys, Player 2 takes WASD, and every match ends with somebody muttering that the other half of the keyboard is easier. 12 MiniBattles removes the argument by giving each player exactly one key: A on the left, L on the right. Nothing else. No aiming, no movement keys, no combos.

What that key does changes every round. A minibattle is drawn at random — a cowboy quick-draw, a golf shot, a viking with an axe, a helicopter over a burning house — and you get about a second to work out whether your button jumps, fires or swings before the other player figures it out first. Each battle has its own winning line, somewhere between three and five points, so a round is over in well under a minute and the next one starts before anybody can complain.

The number in the title is out of date, and by a wide margin. We pulled apart the GameMaker bundle this page loads: it holds 37 separate minibattles, laid out across 76 arenas. The internal room list runs from juego1 to juego44 with seven numbers missing, and there are orphaned sword-fight sprites from a battle that no longer has a room — evidence that the roster has been added to and pruned since 2018. Seven of the minibattles carry six or seven arena variants each, which is why football or lava-climbing can turn up twice in an evening and look like two different games.

It was built by Shared Dreams Studios, the studio of Argentine developer Mariano Maffia. The HTML5 version arrived in November 2018, an April 2019 update added new battles, and it finished second runner-up in that year's CrazyGames Developer Contest. It has since collected a 4.0 rating from 1,702,796 votes on Poki and an 8.4 out of 10 on CrazyGames, and the Android port has passed ten million installs. One honest limitation up front: there is no CPU opponent. We searched the entire 2.17 MB bundle for bot, AI or CPU code and found none. This is a game you play with somebody, or not at all.

Every minibattle we could confirm

There is no official list. The table below is what survived a cross-check between the minigame names published by CrazyGames and twoplayergames and the actual assets sitting in the build on this page.

Minibattle	What your key does
Cowboy duel	Draws and fires. Press before the signal and you lose the round outright
Football	Jumps and kicks a ragdoll striker; goals are scored more by accident than aim
Basketball	Jumps at a backboard, which is also how you block
Golf	Times a swing; twoplayergames records the target as three balls in the hole
Tennis	Returns the rally — the longest exchange in the game
Sumo wrestling	Shoves a jointed ragdoll and tries to keep your own feet down
Boxing	Throws the punch; the ring is small enough that missing is expensive
Thumb wrestling	Pins the other thumb, with a stamina bar behind it
Hand slap	Slaps, or pulls the hand away. Ten separate hand sprites cover the flinch
Ninja board breaking	Chops the plank on the trestle at the right instant
Archery	Charges the bow — there is a dedicated draw-strength bar for each archer
Viking axes and maces	Throws the axe or swings the mace from a longship deck
Tanks	Fires the shell; elevation is on a timer, not a stick
Plane dogfight	Flaps the plane upward and drops rounds on the other one
Spaceships	Thrusts between asteroids and shoots
Martian shooter	Fires at a martian that advances, attacks and retreats on its own schedule
Frog and flies	Fires the tongue at passing flies from a lily pad
Balloon popping	Pops the balloon before the other player does
Helicopter rescue	Lifts a copter over an island or a burning house to pick up survivors
Lava climb	Jumps up platforms while the lava rises underneath

There are more in the bundle — paintball, zombies, log-chopping, bumper cars, gangsters with machine guns, a man carrying a candle — but no source names their rules, so we are not going to guess at them.

Why one key each is the entire design

One-button multiplayer is not a shortcut, it is the point. The format was set in 2014 by Finnish developer Otto Ojala with Soccer Physics, a one-key, two-player ragdoll football game that won the IMGA award for best multiplayer game and spawned a decade of imitators — twoplayergames goes as far as calling one of the 12 MiniBattles minigames "Soccer Physics" outright.

The reason it works on a shared keyboard is arithmetic. A game with four keys per player has to explain eight keys before anything happens, and the person who was not paying attention spends the first round pressing the wrong ones. A game with one key per player has nothing to explain, which means the skill gap between the two people at the keyboard is a gap in reaction and nerve rather than in familiarity. That is also why the two keys are A and L: both sit on the home row, one at each end, so two people can share a laptop shoulder to shoulder without their hands colliding. Symmetric input, symmetric position, no excuses available to the loser.

Playing 12 MiniBattles unblocked

The game is one HTML5 page compiled from GameMaker — no installer, no plugin, no login, nothing written to the machine. That is why it appears on so many "unblocked games" lists and why it keeps working on school Chromebooks and locked-down office browsers: the only thing that has to get through is the page itself. Press play above and it runs inside this tab; the fullscreen button on the toolbar stretches the 1280×720 canvas to fill the screen, which is worth doing when two people are sharing one laptop.

MiniBattles, 12 Mini Battles 2 and the rest

Shared Dreams Studios has taken the same idea in two directions. MiniBattles (July 2020) opens the format to six players on one keyboard — C, N, Q, P and the two arrow keys — with up to 30 minigames, and holds a 4.2 rating from over a million Poki votes. 12 Mini Battles 2 (January 2024) goes back to two players and twelve battles, including street racing and foosball, and rates 3.4 from 586,083 votes. The original is still the one people return to, which is a fair verdict: 37 battles beats 12, and two players on one keyboard is easier to organise than six.

More two-player games on one keyboard

If the one-key format suits you, Drunken Duel 2 is the purest version of it — two stick figures, one shot each. For physics chaos with slightly more input, try Drunken Boxing, or the Random series from RHM Interactive: Basket Random, Soccer Random and Boxing Random, all of which run on the same shared-keyboard principle. The rest of our two-player picks live in the multiplayer category.

1. Find a second person. Sit them at the other end of the keyboard. There is no single-player mode to fall back on.
2. Left player takes A, right player takes L. That is the full briefing, and it stays true for every minibattle in the game.
3. Read the arena, not the instructions. When a battle loads, look for what is between the two characters — a goal, a hole, a stretch of water, a rising floor of lava. That tells you what your one key is for.
4. Take the round, then forget it. Winning lines vary by battle; twoplayergames records the golf one as first to sink three putts. The next battle resets everything.

What research turned up that the play screen does not tell you:

• The button is contextual, never modal. Because each of the 37 battles has exactly one input object per player in the code, there is no charge, no double-tap, no hold-versus-tap system hiding anywhere. If pressing is not working, you are pressing at the wrong moment, not in the wrong way.
• Scenery lies, mechanics do not. With 76 arenas over 37 battles, the same rules come back on a different backdrop. Learn the win condition and the repeats stop catching you out.
• Playing alone is a legitimate stance, not a hack. CrazyGames says outright that you can play as both characters at once. One hand per key is genuinely how solo players use this game.
• Ties go to the person who waits. In the timing battles — the cowboy duel, the board-breaking ninjas — the loser is usually whoever pressed early. Being slower is a strategy here far more often than being faster.
