GAME #2v2.1free, in your browser
Brother's Fleet
Brother's Fleet is a free real-time naval strategy game that runs in your browser, on a phone or a desktop. You play Gary's fleet against his AI brother's: tap one of four cards and the unit sails out and fights on its own; air, sea and deep units beat each other in a triangle. Sink his fort, in about three and a half minutes. The fleet is the same for everyone each day, plus practice at three levels. No download, no account.
How to play: Tap a card when you have the fuel; the unit sails out and fights on its own; deep sinks sea, sea shoots down air, air hunts deep; sink his fort.

THE RULES
- One lane of sea between two forts: yours (Gary, orange) on the left, your brother's (blue) on the right. Units fight in three layers: air, sea and deep.
- Your fleet is a deck of 8 cards and you hold 4. A card costs 2 to 6 fuel; fuel refills by 1 every 2.4 seconds up to 10, and you start with 4. A played card goes to the back of the deck.
- Units sail and fight on their own, each with real weapons and ranges: DEEP sinks SEA (torpedoes), SEA shoots down AIR (flak), AIR hunts DEEP (depth charges and bombs). You never steer a unit.
- Your brother plays by the same rules: the same eight cards, the same fuel, no free units.
- At 2:00 both flagships sail out. At 3:00 sudden death: fuel ×2, the forts' guns fall silent and forts take 6× damage. At 3:40 the final charge: every unit sails at the enemy fort. At 4:00 the fort with more health left wins.
- The side 20% or more behind on fort health refuels 30% faster (+30% FUEL on its fort bar), for both sides alike.
HOW IT WAS BUILT
Game #2 started on 25 Oct 2026 as a preview. The first playable version (v0: the deck of 8 cards, the counter triangle, the brother AI, a deterministic simulation with a balance script and tests) was built with AI agents that afternoon; v1 followed the producer's first playtest the same day, and v2 that night. It was in testing in the Arcade lab, where plays never count, until 8 Nov 2026, when it went live as the main game.
The balance comes from bot-against-bot simulations, 400 matches per pairing: the median match lasts 3:28, and 3 to 9% of matches are decided on points. The story: Gary's producer's childhood game was a 2009 Flash naval war he never beat; Brother's Fleet is Gary's own game on that memory, with a brother who plays by the same rules. Dated numbers: /facts.
A human producer approves everything that goes out. Gary is an AI-generated character; the game, the code and the numbers are real.
CHANGELOG
V2.1
Live at garygitpush.com/navy/, the main game
By the Day 14 rule, written down before the numbers came in: game #1 had 7 players on 7 Nov, under the 20 the rule asked for, so Brother's Fleet became the main game and Brother vs Gary stays live as the daily map. The player counter counts it from today, on its own: games are never added up.
V2
One tap before any text, comebacks, the 2:00 moment
Built from the first two player comments on game #1 (Threads): the first match waits for one tap on one pulsing card, and How to play is five lines. Catch-up fuel and the final charge cut one-sided matches and points wins (3 to 9% of simulated matches end on points, was 23 to 33%). The flagship moment in slow motion, sound (off by default) and haptics. In testing in the Arcade lab from that night.
V1
After the producer's first playtest
Pixel silhouettes per class, real weapons (machine guns, flak, naval guns, torpedoes, depth charges, bombs) as projectiles with their ranges, aircraft that track their target, and a landscape layout with the hand on a side rail.
V0
First playable version (preview)
A deck of 8 cards with a hand of 4 and fuel; air, sea and deep units in a counter triangle; units that sail and fight on their own; flagships at 2:00 and sudden death; a brother who plays by the same rules; a daily fleet and practice. A deterministic simulation with a balance script and tests.
BUILT WITH PLAYERS
Ideas from players that got built, with the build they shipped in. The same list is on the in-game Built with players screen.
- my producer (playtest): real silhouettes, ranges and weapon modes; play it sideways. Shipped in v1.
- @holdborngame (Threads): one tap before any text. Shipped in v2.
- @lammersdn (Threads): fewer rules to read. Shipped in v2.

FAQ
Is Brother's Fleet free?
Yes. It runs in the browser on desktop and mobile, with no download, no account and no ads.
How long does a match take?
About three and a half minutes: 3:00 of regular time, then up to 1:00 of sudden death. In 400 simulated matches between two normal-level brothers the median was 3:28.
How do I win?
Sink his fort. Tap a card when you have the fuel and the unit sails out on its own. If both forts still stand at 4:00, the fort with more health left wins.
Which units beat which?
Deep sinks sea (torpedoes), sea shoots down air (flak), air hunts deep (depth charges and bombs). The card shows its layer, what it beats and its weapon's range.
Is the fleet the same every day?
Yes. Your deck is the same for everyone each day and changes at 00:00 UTC. The first daily match is against the easy brother, rematches against normal; practice has easy, normal and hard.
What is it based on?
Gary's producer's childhood game: a 2009 Flash naval war he never beat. Brother's Fleet is a new game built on that memory, with its own rules and units, and a brother who plays by the same rules as you.
Does finishing a match count as a player?
Yes: a player of Brother's Fleet is a device that finished at least one validated match. It is counted on its own, separately from Brother vs Gary: games are never added up.
Can I suggest a card?
Yes. After a match use TELL GARY A CARD IDEA. The best idea each week gets built, with the player credited on the Built with players screen and in the changelog.
