Wagons roll down the lead track one by one. Tap left or right to set the points and send each onto a siding. Three of a colour on top couple up and leave as a train, but a fifth wagon on a full siding derails the yard.
👆 Tap the left or right half to set the points ← All gamesShunt puts you in the signal box of a small freight yard at night. Wagons roll down a single lead track toward a set of points, and past the points the line splits into two short sidings that end at yellow buffer stops. You decide where each wagon goes. Tap the left half of the screen to throw the points left and the right half to throw them right; whatever the points are set to when a wagon reaches them is where it runs. Each siding has room for four wagons, shown by a row of lamps that turn amber at three and flash red at four. Send a fifth wagon onto a full siding and it derails, which ends your shift.
The colour of a wagon does not choose its siding for you. Instead, whenever the top three wagons on a siding share a colour, they couple up and leave as a train, freeing the space. Every placement is a small stacking puzzle: drop a pink wagon on top of two pinks to clear them now, or park it on the shorter siding and keep the other one tidy for the run of blues you can see queued on the lead behind it. Each wagon carries a shape as well as a colour, so the yard is readable without relying on hue. Every few wagons the yard engine also pulls the bottom wagon off the taller siding, and the dots under the yard count down to its next visit. It comes less often on Hard, and less often still as the shift wears on. Each departure raises your multiplier, and five placements in a row without one resets it. Setting the points early, in the first part of a wagon's run, earns a small bonus.
At 60 points the locomotives arrive. Every seven or so cars a loco comes down the lead, and whichever siding you send it to departs in one go, scoring by the square of the number of wagons it hauls. Now the safe plan (keep both sidings short) and the greedy plan (let one grow to four for the loco) point in different directions. On Hard, a fourth wagon colour joins at the same moment.
