DISCLAIMER: This is a fictional game. Do NOT throw rocks, golf balls,
or any objects from bridges, overpasses, or at moving vehicles in real life. Doing so is
a felony in most jurisdictions and can cause serious injury or death. The developers do
not endorse, encourage, or condone any such behavior. Play responsibly.
You're standing on an overpass with a pile of rocks (or golf balls). Cars drive by below. Drop projectiles on them to rack up damage — measured in dollars of repair cost. You've got 60 seconds, extendable through bonus events. Biggest total score wins.

The Round Timeline
0s — First throw
The 60-second clock doesn't start until you release your first rock. Move and aim freely before that.
30s — Wind kicks in
"Starting to get windy." 15–20 mph from some direction. Arrow shows it, shakes with intensity.
40s — DeLorean appears
A rare time-travel Easter egg drives in. Hit it for Great Scott! +10s.
≤5s — Last throw
The banner fires and a beep-per-second cues your final throw.
Power Meter
Hold the throw button to sweep a power bar. Releasing at the top deals more damage and throws the rock further. The aim arc is visualized — lead the car.
Projectiles
🪨 Rock
Heavy. Full damage (100%). Low wind drift. Shatters on landing. Best all-around pick.
⛳ Golf Ball
65% damage but bouncier, faster, more wind drift. Chains combos and flybacks more easily.
🎳 Bowling Pin
Full damage, tumbles end-over-end, slightly floaty. Bowls through rows of traffic for giant combos — Pin Kings territory.

Strategy Tips
• Lead the target — fall time is ~1 second at full gravity. Throw where the car will be.
• Aim for hoods and windshields — center hits on flat panels pay best (see Scoring).
• Chase the streak — missing a throw breaks your streak back to zero. Fire thoughtfully once it's on.
• Backwards hits are time — every third one is +10s. Flybacks count too.
• Wind favors rocks for precision, golf balls for chaotic combos.
• Wall bounces are multiplicative — a 3-bounce flight can 4.5× your next car hit.

Scoring — The Full Nerd
Master Formula
Every single hit evaluates this formula, in this exact order:
MIN_PAYOUT is $200 — any hit pays at least this, even a pure edge graze. The floor is applied twice: once after combo, once after all remaining multipliers. Multipliers stack multiplicatively in the order shown.

Dead-center hood hits score the full repair cost. Edge grazes collapse toward $0 (clamped by MIN_PAYOUT). Front bumpers pay 30% more than rears.

Power Multiplier

Feather drop → 1.0×

Mid-meter → 2.0×

Max-charge → 3.0×
Combo Multiplier (per-throw)
comboMult = carHits [1st car = 1×, 2nd = 2×, 3rd = 3×, … no cap]
One rock, multiple cars. Each successive car on the same projectile multiplies the hit's damage by its position in the chain. A single rock hitting 5 cars stacks 5×, 4×, 3×, 2×, 1× on the respective hits.

A "hit-throw" is any throw that scored at least one car hit. A miss (rock lands without connecting) resets the streak tier to 0. Reaching MEGA also grants a one-shot Triple Toss charge — your next throw fires three rocks in an 8° spread.
Backwards Hit 5×
backMult = 5 if (carHits ≥ 2 AND velocity.z > 2 AND !_backwardsUsed)
After hitting a car, the rock deflects. If it has positive Z velocity (moving back toward the camera) when it hits the next car, that hit scores 5×. Only one backwards hit per rock. Counts toward the backwards-trio time bonus (see below).
Wall Bounce Multiplier
wallBounceMult = wallBounceCount × 1.5
Side barriers of the highway bounce a rock back into traffic. Each bounce adds 1.5× to a running multiplier stored on the rock: 1st = 1.5×, 2nd = 3.0×, 3rd = 4.5×, and so on (no cap). Applied on every subsequent car hit by that rock. Stacks multiplicatively with streak, combo, and backwards.

Golf balls do 65% of a rock's damage but bounce 60% harder, fly 15% faster, and fall 40% quicker (heavier effective gravity = snappier cadence). They're also blown around by wind twice as much. Rocks win on raw damage; golf balls win on combo depth and unpredictable ricochets.
Bowling pins match rocks for damage but fly a hair slower and float longer (0.9× gravity) so you can watch them tumble end-over-end. They excel at mowing laterally through a row of cars: each pin hit becomes the next car's combo multiplier, and pins keep their momentum after impact — a well-placed throw can pick up 10+ cars in one go. Wall bounces are brutal with pins since the multiplier stacks (no cap).
Flyback Bonus — +$20,000
If a rock that's already hit at least one car bounces back over the bridge deck (crosses Z = −5 going upward with Y above 6m, heading toward the camera), it's a Flyback. Flat +$20,000 bonus awarded once. Also counts as one tick toward the backwards-trio counter.
Time-Extension Bonuses
+10s · Backwards Trio
Accumulate 3 backwards hits (backwards-5× hits and flybacks both count) and the round clock gets +10s. Counter resets after each trio, so you can earn it repeatedly.
+10s · Great Scott!
The DeLorean appears once per round at the 40s-elapsed mark. Any direct hit awards +10s and plays "Great Scott!"
Wind Physics
mag ∈ [3.0, 4.0] m/s² (rendered as 15–20 mph × 5)
direction always has a horizontal (NE/NW/SE/SW) component
activation at 30s elapsed
re-roll every 15s with a 1-sec ease to the new target
heightFactor = clamp(0, 1, (y − (ground + 0.2)) / 5)
velocity.x += mag.x × projectile.windMult × heightFactor × dt
velocity.z += mag.z × projectile.windMult × heightFactor × dt
Wind only affects airborne projectiles and scales with altitude: 0× at ground level, ramps linearly to full strength by 5 m above the road. Low bounces barely drift; high arcs get blown around. Rocks feel 0.5× wind, golf balls feel 1.0× — twice the drift on a golf ball at the same height and wind speed.

Worked Examples
Example 1 — Perfect Porsche hood at max power, cold start:
costMax=$5,000, xMult=1.0, zMult=1.0, powerMult=3.0, combo=1, back=1, streak=1, dmg=1, wall=1
rawPoints = 200 + (5000-200)×1×1×3 = $14,600
basePoints = 14,600 × 1 = $14,600
points = 14,600
Example 2 — Same shot but 3rd car of a combo on a SUPER streak with 1 wall bounce:
costMax=$2,500 sedan, xMult=1.0, zMult=1.0, powerMult=3.0
combo=3, streak=5, wall=1.5
rawPoints = 200 + (2500-200)×3 = $7,100
basePoints = 7100 × 3 = $21,300
points = 21,300 × 1 × 5 × 1 × 1.5 = $159,750
Example 3 — Backwards + MEGA on a truck:
costMax=$2,000, xMult=0.8, zMult=1.0, powerMult=2.5
combo=2, backMult=5, streak=10, dmg=1, wall=1
rawPoints = 200 + (2000-200)×0.8×1×2.5 = $3,800
basePoints = 3800 × 2 = $7,600
points = 7600 × 5 × 10 = $380,000
