Vector has one verb — nudge your velocity by one square — and everything else follows by arithmetic: the car draws its line, the corner arrives, and either you spent the last three turns preparing for it or you drew a red line into the wall. Because there is no randomness anywhere on the sheet, the entire race is computable from the board, and the players who win are the ones who actually compute it. This guide is built from the game’s own balance measurements — the same exact-solver maths that plays the CPU on Hard.
Count the braking triangle before you build the speed
Acceleration is one square per turn, in every direction, with no brake pedal — slowing down costs exactly the turns that speeding up did. A car moving 5 needs five turns of full braking to stop, and while it brakes it still travels 4+3+2+1 = 10 squares — the nudge applies before each move, so the last turn moves zero. That little triangle of numbers is the most important object in the game: before you add a square of speed on any straight, count the squares to the wall ahead and compare. If the wall is closer than your triangle, you are not going fast — you are already crashing, and the game just hasn’t drawn it yet. Our exact racer’s optimal lap on this track is 20 turns, and what makes it optimal is almost entirely braking one turn later than feels safe — never earlier.
Diagonals are almost free — use both axes in every corner
Velocity lives on two independent axes, and the speed cap applies to each separately — which means a corner is not a place where you stop and turn, it is a place where one axis hands its speed to the other. The classic Racetrack line swings wide before the corner, lets the old axis bleed off one nudge at a time while the new axis builds, and clips the apex on the way out carrying speed on both. A car that enters square, stops, and rebuilds from zero loses three or four turns per corner to a car that sweeps — and there are four corners per lap, plus the three checkpoint bands (right, bottom, left, in that order) making sure everyone actually goes around all of them.
A crash is a price, not a punishment
Leaving the track stops you where you were, zeroes your velocity, and spends the turn — nothing more. No wreck, no respawn, no penalty lap. The real cost is the momentum itself: every square of speed took a turn to build and will take another to rebuild, so a crash at speed 4 is roughly an eight-turn mistake. Read that backwards, though, and it becomes a tool: if you have genuinely misjudged a corner, a deliberate crash-stop now, at low speed, is often cheaper than the heroic save that fails two turns later at high speed. The strongest players treat the crash rule as a parking brake with a fee — ugly, occasionally correct — while the full-throttle bot that never lifts crashed out of 100% of simulated matches.
Soft blocking: park on the square they need
You may drive through the other car, but you may not end your move on its cell — and since the cars alternate turns, that rule is quietly a weapon. Every corner has one or two cells that the good entry lines want to land on, usually the wide braking squares just before the apex. Sit on one at the right moment and every line through that corner gets one nudge worse for your opponent — not a wall, just a tax. It is worth half a turn here and there, and Vector’s matches are decided by half-turns.
Race the clock, not the other car
A match is two heats with the starter swapped, scored by your combined turn count — and that structure is a measurement, not a flourish. In a single race, moving first is worth 63–74% even with the classic fair-finish rule; no scoring patch removed it, so the match hands the half-turn edge to each player exactly once and adds the clocks (after the change, mirror matches measure 48–50%). Two things follow. First, losing heat one by a couple of turns loses nothing yet — stay calm and take clean corners, because a blow-up costs more than a deficit. Second, both cars finish out every heat: your time still counts after your opponent crosses, and a car that gives up records the 60-turn cap. And cross the line fast — if the combined totals tie, the tie goes to combined overshoot past the line, so momentum at the flag is literally worth something.
Beating the CPU ladder
All three difficulties pick from the identical nine candidate circles you see. Easy is a greedy racer that chases progress around the ring and slips 20% of the time — it corners honestly but too carefully, so you beat it by braking later and sweeping corners on both axes. Normal and Hard play the exact turns-to-finish table (a reverse breadth-first search over all 226,512 position-and-velocity states) with 15% and 5% slip rates — you will rarely out-corner them, so your wins come from their slips: when Hard fumbles a move, it loses real momentum, and one clean lap of yours is suddenly enough. Hard laps in the true optimum of 20 turns when it doesn’t slip. It always can slip — a perfect machine is a wall, not an opponent — but do not wait for luck twice: bank a clean first heat and make its one mistake decisive.
Vector is the third of our racing originals, and the only turn-based one — if you want the same track-craft at real speed, Drift Duel’s guide covers steering-as-braking, and Wake’s guide covers slipstream timing. All three are free, in the browser, on the same keyboard — or the same phone, since every move in Vector is a single tap.
