AI Browser Game Jam: what four editions built

The AI Browser Game Jam is a recurring itch.io jam, hosted by Focaccai, for free browser games built heavily with AI. It ran four times in 2026, from February to August, and the fifth edition takes submissions from October 17 to 31, 2026. We list 46 entries from the first four, each with its final placement.

It is a different animal from Vibe Jam 2026 and its 945 entries. The rules ask for something else, and the games came out different too.

Four editions at a glance

Each edition ran for two to three weeks, and each was bigger than the last. Submissions ran from February 20 to March 10, April 11 to 30, June 6 to 24 and August 1 to 18. The counts come from each edition’s results page; the last column is how many of its entries we list.

Edition	Entries	Ratings	We list
1	29	96	5
2	42	226	5
3	77	596	11
4	125	1,034	25

Each edition had a theme, optional from the second one on, and its own winner:

Edition	Theme	#1 overall
1	Ghost in the Machine	Rogue Memory, tied with 6-bit Vanguard
2	Alien	Alien Escape Pinball
3	Familiar	Pyramid Wars Demo
4	Charge	Plug & Prosper
5	Announced when submissions open	–

Ratings grew faster than entries. The fourth edition had more than four times as many entries as the first, and drew more than ten times the ratings (results).

The rules: any AI, for anything

The jam exists “to encourage more people to experiment with AI-assisted game development,” according to the first edition’s page. The fifth edition’s page puts it more bluntly: “This game jam is completely open. Use whatever AI you want for whatever you want.”

• Mostly AI, and not only code. Editions one to three asked for at least half of a game to be AI-generated. The fourth and fifth ask for the “majority of the game.” AI can make the art, code, design, music, sound or anything else, and human editing is welcome.
• Free, in a browser, no download.
• Several entries are fine if they are significantly different, and an older project counts if most of the submission is new (fourth edition rules).
• AI Usage is a rating category. Every edition’s results page scores entries on Overall, Fun, Graphics, Audio and AI Usage. Editions three and four added Theme.

Set that beside Vibe Jam 2026, and the two jams ask for different things. Vibe Jam’s terms are from its jam page.

	AI Browser Game Jam	Vibe Jam 2026
AI rule	Half, later most, of the game, art and music included	At least 90% of the code
Engine advice	LittleJS and Three.js suggested	Any engine, Three.js recommended
Multiplayer	Not mentioned	Preferred, not required
Entries per person	Several, if different	One
Prize money	None listed on the jam pages	$25,000, $10,000 and $5,000, plus 12 prizes of $1,000

Single-player, light on engines, partly hand-made

The entries look as different as the rules. Vibe Jam recommended Three.js and preferred multiplayer, and 68% of its entries we list run on Three.js, with 45% online. The AI Browser Game Jam suggested Three.js too, next to LittleJS, but said nothing about multiplayer, and its entries went another way.

Among the entries we list	AI Browser Game Jam	Vibe Jam 2026
Online multiplayer	0%	45%
Run on Three.js	7%	68%
Name no engine	59%	19%
List phones	22%	67%
Roguelikes	20%	6%
Shooters	4%	23%

Where an engine is named, it’s Phaser on 4, plain canvas on 5, Three.js on 3, Godot on 5 and LittleJS on 1. Roguelikes, strategy and simulation all show up more often than at Vibe Jam, and shooters much less.

1. Strategy1226%
2. Action1124%
3. Simulation1022%
4. Puzzle920%
5. Roguelike920%
6. Arcade715%

Out of 46 games; a game can count in several bars.

The AI share differs too. Our entries record 24 of these games as partly made with AI. Across our whole catalog, 24 games carry that label, and 24 of them come from this jam. Riders of the Nine Planes, for one, says on its page that its music is not AI-made.

Tools are where our records run thin. We have a tool on record for 27 of the 46, and 4 of those name the Claude app. Our Vibe Jam entries draw on the jam’s submission form. These draw on each game’s itch.io page, where the jam calls sharing your tools and prompts “encouraged but optional.”

The winners we list

Of the games we list, 5 finished in the top three of their edition. The theme often shows.

Rogue Memory (edition 1, #1)

Ghost in the Machine, taken literally. Rogue Memory makes you GHOST.EXE, a deleted AI walking a first-person maze built from its own memory, five layers down to the kernel. Fights are turn-based: attack, scan for a weak point, or retreat. It shares first place with 6-bit Vanguard on the results page, and its entry names the Claude app.

Alien Escape Pinball and Alien Orbital Assault (edition 2, #1 and #2)

The Alien theme took both top spots. Alien Escape Pinball is a full pinball table with ramps, multiball and an egg that hatches an alien, plus voice lines read by text-to-speech. You can nudge the table by swiping on a phone. It was made by Focaccai, who also hosts the jam (results).

Alien Orbital Assault is a vertical shooter built as one long boss fight. Shoot down every orbiting drone to open a short window, then hit the boss before it closes. Wrecks drop the ammunition and fuel you spend.

A Low Poly Dungeon Game (edition 3, #2)

A Low Poly Dungeon Game builds a first-person dungeon from a seed, so the same seed always gives the same layout. Three gated zones, a boss and a crown, drawn in a PSX style. It runs on Godot and has touch controls.

TECHNICAL DEBT (edition 4, #3)

TECHNICAL DEBT casts you as a parent laid off after an employer automated the job. You put household needs on credit to earn points toward a vacation, resell the boxes piling up, and go bankrupt on purpose: each bankruptcy carries a lesson into the next run.

Just below the podium in edition four, the Charge theme gets two more readings. In Riders of the Nine Planes (#4), your mount builds energy as you ride, then charges at a target and releases a spell. PLUGS (#6) is a puzzle about lighting a dark house with plugs, cords and a breaker.

Entering the fifth edition

The fifth edition runs from October 17 to 31, 2026, and its theme is announced when submissions open. Its rules read like the fourth’s: free, in a browser, no download, with the majority of the game AI-generated. Here is what the first four suggest:

1. Write down how you used AI. Raters score AI Usage, and your game page is where they learn it. Name the tools, the models and what you made by hand.
2. Single-player is fine. Online games among the 46 we list from the four editions: 0. The winners include a pinball table and a debt sim.
3. Use the theme, or don’t. It’s optional, but the winners above show it can give a small game its hook.
4. Test it on a phone. 3 of the 5 top-three games we list play on one. A browser game gets opened wherever its link lands.
5. Let AI make the sound too. The rules allow AI music and sound, and Audio is its own rating. See AI sound effects and music for games.
