About Stonewall TT

Stonewall TT is a motorbike road racing game that runs in your browser. The roads are the point: not a circuit with run-off and gravel traps, but public roads closed for the day — a dry-stone wall a metre from the white line, a hedge on the other side, a lamp post at the apex of the village corner, a blind crest that lifts the wheels at two hundred and forty. Three courses of six to seven kilometres, every corner with a name, and the fastest way round is the way that keeps you on the tarmac.

The bike is the other point. You do not steer it like a car; you lean it, and the physics does the rest. A leaning bike turns at a rate set by its speed and its lean, so the same forty degrees that threads a hairpin at sixty kilometres an hour barely bends the road at two hundred. Grip is one budget shared between braking and cornering: brake hard while upright, trail it off as you lean in, and get back on the throttle as you stand the bike up. Ask for both at once and the front tucks. The tachometer is a real one — gear, revs, the shift point — and the automatic gearbox can be switched off for anyone who wants to do it themselves.

Three classes step up through the career. The Supersport 600 is quick and forgiving. The Superbike 1000 is the one in the video everyone has seen — a hundred and fifty horsepower between stone walls. The Senior TT bike is the fastest thing on the island. Each one comes with a team contract, earned by finishing a season in the top three, and each one has a garage: engine, brakes, tyres and chassis, three levels apiece, paid for with prize money and felt in every corner.

A career season is six rounds. Saturday is a four-minute qualifying session on an empty road, your best lap set against the AI riders' own simulated laps; Sunday is the race, points for the top fifteen and prize money for every finisher. On the grid is a rival — the fastest rider in your class, red bike, a bonus every time you beat him. The AI riders brake, pick lines, overtake and make mistakes at a rate that depends on their skill, and they get quicker season by season.

Live races put eight riders in a room per class. Press play and you are matched with whoever is waiting; empty seats are filled by AI riders, marked as such, and the room itself runs the race so everyone sees the same thing. Your garage upgrades come with you.

How to play Stonewall TT

Start with a quick race on Glen Road in the Supersport class, club pace, three laps. Hold W and watch the tachometer: the automatic gearbox shifts at the top of the green. The board on the left names the next corner, its distance and a rough entry speed. Brake in a straight line until you are near that speed, then lean — hold A or D — and the bike rolls over. Roll the throttle back on as the corner opens out.

The red and white kerbs mark the inside of the corners, the 100 and 50 boards the braking zones, and the walls the outside of everything. When the board flashes BRAKE you are carrying too much. Crests at speed lift the wheels, and the bike will not steer in the air, so be settled before the jump.

Once a lap comes in without a crash, go to Career, sign for a team, and qualify. Then spend the first prize money on tyres.

Stonewall TT — frequently asked questions

What is Stonewall TT?

A free 3D motorbike racing game that runs in your browser. The courses are closed public roads — stone walls, hedges, village streets and a moorland climb — and the bikes are superbikes in three classes. There is a full career, a quick race against AI riders, a time trial, and live races for up to eight riders.

How do you ride a bike in a game?

You steer by leaning: hold A or D (or the arrows) and the bike rolls further over until it reaches the limit of the tyres, about 48° on dry tarmac. The same lean turns tighter at low speed than at high speed, so the fast corners are taken with a small lean and the hairpins with the bike right over. W is the throttle, S the brake.

Why do I keep crashing?

Almost always braking while leaned over, or arriving at a corner too fast. Braking uses the same grip as cornering, so brake hard while the bike is upright, ease off as you lean in, and get back on the throttle as you stand it up. The board on the left names the next corner with a rough entry speed and flashes BRAKE when you are carrying too much; the 100 and 50 boards stand before every big bend. Above walking pace, a wall is a crash.

What happens when I crash?

The rider goes down, the bike slides, and about three seconds later you are back on the road at a standstill pointing the right way. Riders who are down or recovering are ghosted, so nobody piles into them. Contact between riders at racing speed slows both; hitting someone from behind at a big closing speed puts you down.

What are the three courses?

Glen Road (5.8 km) is a fast valley road between stone walls and pines with a plunging hairpin at the mill. Harbour Run (6.6 km) has sea-wall straights, a tight town section past the quay and a climb through the hedges. Mountain Mile (7.4 km) is the big one: a long open climb over the moor, blind crests, and a 260 km/h drop into the finish. Every corner is named, and the boards tell you which is coming.

How does the career work?

You sign for a Supersport 600 team. A season is six rounds over the three courses: a four-minute qualifying session sets the grid against the AI riders' simulated laps, then the race pays points to the top fifteen (25-20-16-13-11-10-9-8-7-6-5-4-3-2-1) and prize money to every finisher. Beat your rival for a bonus. Finish the season in the top three and a Superbike team offers a contract — the bike comes with it. Do it again and you ride the Senior TT.

What do the upgrades do?

Prize money goes into the garage: engine (top speed and acceleration), brakes, tyres (grip and lean limit) and chassis (lean speed and stability), three levels each per bike. They feed straight into the physics, and they count in live races. The AI riders upgrade too as the seasons go on.

Is there multiplayer?

Yes — live rooms of eight riders per class. Press play and you are matched with anyone else waiting; empty seats are filled by AI riders, clearly marked AI, and a rider who drops out is taken over by the AI. The room runs the race, so every rider sees the same race. Three laps, standing start.

What are the controls?

W / ↑ throttle, S / ↓ brake, A D / ← → lean, C camera (chase, onboard, TV), Tab standings, R restart, Esc pause. With the automatic gearbox off, E shifts up and Q down. On a phone, pads at the bottom of the screen do the same.

Does it work on a phone?

Yes, in landscape, with touch pads and a compact HUD. It is a 3D game with eight kilometres of road in view, so a recent phone helps.
