GAME #3v0.8.0free, in your browser
Brother's Rally
Brother's Rally is a free rally game that runs in your browser. You drive one stage, about 2.4 km of autumn dirt through fields, a farm, a forest and a panel-flat estate, against the clock and the ghost of Gary's AI brother, who drove the same physics before you started. Pick Gary's sedan or the brother's 4×4, listen to the co-driver's pace notes and beat his time. It is an early build: on a PC you drive with the keyboard, on a phone you hold the left or right half of the screen to steer while the gas is automatic. No download, no account.
How to play: Hold ↑ for gas, steer with ← →, Space for the handbrake; follow the pace notes and reach the finish line before the brother’s time.

THE RULES
- One stage, the same for everyone: Stage #1, about 2.4 km of autumn dirt through fields, a farm, a forest and a panel-flat estate.
- Your brother drove it first, on the same physics as you: his run is the blue ghost and the time to beat. Three brother levels in the settings: easy, normal and hard.
- Two cars: Gary's sedan (rear-wheel drive) and the brother's 4×4. Assists: ROOKIE, PRO or SIM; gears automatic or manual.
- The co-driver calls the corners ahead: direction and severity from 6 (flat out) to 1 (very slow), hairpins, crests and what comes next.
- Leaving the road costs seconds, and hits dent the car (the damage bar); R restarts the run.
- Medals: bronze for the easy brother's time, silver for normal, gold for hard.
HOW IT WAS BUILT
Game #3 started on 8 Nov 2026 at 05:50 CET as a prototype. The first playable stage (rally physics in a deterministic simulation at 120 Hz, a brother AI that drives the same physics, ghosts, cameras, pace notes and sound) was running at 07:04, 74 minutes after the first commit, built with AI agents. The physics were reworked the same evening after the producer's first drive.
A free-roam valley was tried on 8 Nov and shelved the next night: it froze on the producer's PC, and the daily stage is the game. Since then: one designed stage instead of generated ones, the brother's three levels spaced 4 to 5 seconds apart, a handling tuning screen, adaptive music, and both cars rebuilt. On 11 Nov 2026 it went live as the main game, labelled an early build. 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
V0.8.1
Phone: you drive the pedals now
Phone: you drive the pedals now (GAS + BRAKE), auto gas is an option in settings.
V0.8.0
New player cars
Gary's sedan and the brother's 4×4 are now 3D models generated from their concept drawings, loaded after the title is on screen; phones get lighter files. The lamps, the glass, the driver, dents, dirt, cracked glass and the ghost work on the new cars, and they carry our own plates (GP 1000, BRO 4X4). The cockpit view keeps the old interior. The detachable bumper and the loose parts (mirrors, roof load) are gone. If the car files do not load, the game uses the previous cars.
V0.7.1
The leaderboard
A leaderboard for the stage, one per car class (CARS and 4×4), under LEADERBOARD on the title and result screens. A finished run is sent in the background; the server re-drives it from its inputs with the game's own physics and puts it on the board only if it gets the same time. The result card shows VALIDATED and your place, or why the run was refused. ROOKIE, PRO and SIM share a board and show as tags. The brother's three times are on the board as unranked rows. RACE THE RUN ABOVE lets you race the run just above yours as a ghost. Rows show an anonymous tag like DRIVER 7KQ2, or your Gary Arcade nickname if you switch it on. Runs the AI drove, even in part, are never sent. Fixed: pressing the recover key no longer skips the car forward.
V0.7.0
Painted hills, a smoother first minute
Painted forest hills around the stage, a smaller and warmer sun, haze in the distance and a dust plume behind the cars. A new camera view for a phone held upright. The title screen no longer stalls, and the game prepares its graphics before GO, so a run does not stop to compile them. A new player first races the easy brother. The result card leads with RETRY and adds SHARE. A simple graphics mode is in the settings.
V0.6.1
Fixed: blank screen on Safari and iPhone
Fixed: a blank screen after the start on Safari and iPhone browsers when the game lowered its resolution. The camera no longer flies off at very low frame rates.
V0.6
Playable on a phone
New touch controls: hold the left or right half of the screen to steer, the gas is automatic, BRAKE above the right arrow (the old pad and pedals stay in the settings). A phone layout in both orientations, and a lighter first load: the music now arrives after the title. Tested on emulated phones; real-phone feedback welcome. No leaderboard yet.
V0.5
Live at garygitpush.com/rally/, the main game (early build)
One designed autumn stage for everyone, golden-hour light, adaptive music, the brother's levels spaced 4 to 5 seconds apart, both cars rebuilt, a handling tuning screen (H). From today the player counter counts it, on its own: games are never added up. No leaderboard yet.
V0.4
Free roam (shelved)
An open 1.8 km valley to drive around. Shelved on 9 Nov: it froze on the producer's PC, and the daily stage is the game. The code stays.
V0.3
After the producer's first drive
About twice the engine power, the car keeps pulling while it slides, wider corners and run-off, a rough road; ROOKIE / PRO / SIM assists for the keyboard.
V0.2
A world you can hit
Fences, bushes, bales, crates, barrels and logs that break; dents, cracked glass, a lost bumper and a damage bar; off-road resets with a time penalty.
V0
First playable stage (prototype)
Rally physics in a deterministic simulation, generated 3 to 4 km stages, a brother AI that drives the same physics, his ghost, three cameras, pace notes, sound and touch controls.
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): more power, a car that still pulls while it slides, wider corners. Shipped in v0.3.

FAQ
Is Brother's Rally free?
Yes. It runs in the browser, with no download, no account and no ads.
Can I play it on a phone?
Yes. Steer with ◀ ▶ and drive the pedals yourself: hold GAS to accelerate, tap BRAKE to slow down (hold it to reverse). Use one thumb for the pedal and the other for the arrows. It plays upright or sideways. If you want one-thumb driving, an auto-gas assist is an option in the settings; runs driven with it are tagged AUTO GAS on the leaderboard. The controls are new, so tell Gary what feels wrong.
How long is a run?
About two minutes. On the 2.4 km stage the brother's AI sets the medal times: in the CARS class (Gary's sedan and supermini, the brother drives a hatch) 2:06.00 on easy (bronze), 2:01.41 on normal (silver) and 1:56.39 on hard (gold); in the 4×4 class 2:13.87, 2:09.04 and 2:04.17 (simulated with the game's own physics, rally-0.3, 11 Nov 2026).
What do the medals mean?
Bronze: you beat the easy brother's time. Silver: the normal one. Gold: the hard one. The times are his runs on the same stage, in the same class of car.
Does finishing a run count as a player?
Yes: a player of Brother's Rally is a device that drove the stage to the finish line at least once, in a validated round. It is counted on its own: games are never added up.
Is there a leaderboard?
Yes, one per car class (CARS and 4×4), in the game under LEADERBOARD. A finished run is sent in the background and goes on the board only after the server has re-driven it from its inputs, with the game's own physics, and got the same time. Every row shows the driver-aid preset (ROOKIE, PRO or SIM). Rows show an anonymous tag; a Gary Arcade profile can switch its name on. You can race the run just above yours as a ghost.
Can I suggest something?
Yes. Use Tell Gary what to fix on the title screen or the Tell Gary box on the home page. What gets built is credited here and in the changelog.
