If you are getting really stuck and couldn’t find any hint guide for you. Here is a full guide with all hints. Spoiler warming!
– If stuck on a level, go on and do other things! e.g. Andromeda 12 and 14 are notoriously hard despite being in the first constellation.
– When you return to it, try talking to yourself aloud about what you can/can’t do
– Drawing things out on paper can be helpful
– The difficulty level is basically random. Some of the high-numbered levels in the later constellations are much simpler than you might expect.
– Don’t forget to double check how many carriages there are on a train
Hint 1: The orange alien will be the first one to go to their box.
Hint 2: The two purple aliens are each beside a purple box. Don’t assume that’s the box they’ll be going to.
One of the hardest in the game!
Hint 1: don’t assume that aliens will be delivered to the box nearest them
Hint 2: the map is symmetric across the horizontal line, but your route won’t be
Hint 3: okay so let’s divide the map by that horizonal line. In each half you’ll have two purple aliens staring at a purple box in front of them. You’ll do different things to deliver the purple aliens in each half.
Hint 4: in one of the halves, you won’t be delivering the purple aliens to the box in front of them
Hint 5: in that half, you’ll be delivering the purple alien to the box in front of the other purple alien and vice versa
Hint 6: the first alien you pick up will be orange
Hint 7: every orange alien can be reached on multiple sides
Hint 8: you can pick up an orange alien and roll past other orange aliens only to pick them up later
Hint 1: you need to deliver the two orange aliens to their boxes first
Hint 2: the bottom orange alien is the first one you’ll want to deliver
Hint 1: you’ll be picking two up aliens, delivering them, then picking up another two and delivering them
Hint 2: you have two alleys you can go through to pick up aliens. Which one should you go through first?
Hint 3: you’ve probably developed an aversion to picking up green aliens first. It’s okay, you can get away with it here! (the second train carriage won’t get green because you’ll have to pick up on orange one next)
Hint 1: since you only have one carriage you know you have to pick up and deliver the orange and purple aliens first. Try to figure out which
Hint 2: you pick up the purple alien first
Hint 3: with a purple alien in the train carriage, you won’t pick up any green aliens when you move past them
Hint 4: go /around/ the green alien in the upper left to get to the purple box
Hint 1: although there are six aliens and two carriages, here you /won’t/ be doing only three pick-up-and-delivery segments
Hint 2: The three boxes on the left are harder to fill than the the other three, figure out how you can do those first
Hint 3: The lower-left orange box will be filled with an orange alien from the bottom half of the area
Hint 4: The open space to the left of the three leftmost boxes will go unused
Hint 1: it’s intentional that there is a single open space between the two green aliens
Hint 2: remember that if two aliens try to get on the train at the same time, they collide and neither alien gets on first (“collision”)
Hint 3: pick up and deliver one orange alien, then use the collision trick to keep the train empty as you go get the other orange alien
Hint 1: This one I found useful to work backwards on. Which are the two boxes you’ll be filling last?
Hint 2: The last two boxes you’ll be filling will be the two in the bottom right.
Hint 3: To fill the last two boxes in the bottom right in one pass, you’ll want a green alien in the first carriage and an orange in the second carriage.
Hint 4: How can you set things up so the first green alien you pick up goes in the first carriage?
Hint 5: You’ll start by picking up by two orange aliens then delivering the first one
Hint 1: you’ll want to start by going leftward
Hint 2: the orange alien near the exit must wind up in the orange box near the exit, and will be the last alien you deliver
Hint 3: the purple alien near the exit is not going to be the one that goes to the purple box near the exit
Hint 1: You won’t be picking up the two purple aliens at the same time
Hint 2: Like previous levels, the tricky thing is the two boxes near the exit, since you can’t fill both of them at the end of your route. The last box you’ll be fulfilling is the the lower of the two.
Hint 3: How can you make sure a purple alien is in the front seat when you get to the exit?
Hint 1: you have six aliens and two spots in your train. You’ll be making three-pick-up and delivery segments.
Hint 2: yes, you’ll be doing a ton of looping back and around
Hint 3: start with delivering two orange aliens
Hint 4: the third alien you deliver will also be orange
Hint 5: you’ll want to access the orange aliens from above before coming back to them from below
Hint 1: the first alien you pickup will be the purple one on the lower left
Hint 2: think of different ways you can go through the space between the four purple boxes
Hint 3: you’ll want to pick up and deliver an orange alien before you go return to the junction
Hint 4: the first time you go through the junction it’ll be horizontal, the second time it’ll be vertical
Hint 5: the two purple boxes on the left will be filled first
Hint 1: You will need to use all directions of all four junctions
Hint 2: It’s not an accident you can access the leftmost orange alien from above
Hint 3: The two boxes on the right side of the area will get filled before the two boxes on the left side of the area will be
Hint 4: The orange alien from the left will wind up in the orange box on the right
Hint 5: The first junction you go through will be the one on the upper right
Hint 1: All four of the boxes on the upper half will get filled before the four boxes on the bottom
Hint 2: Pick up two orange aliens first
Hint 3: Be choosy about which purple alien you pick up first
Hint 4: You won’t need all four directions of the upper of the two junctions
Hint 1: the first junction you’ll go through is the one on the lower right, followed by the one on the upper right
Hint 1: you won’t be using the junction at the start
Hint 2: the two boxes near the exit will be the first two to be filled
Hint 3: you will need every direction of the junction
Hint 4: you’ll want to hang around the edges of the area a lot in order to have space to manoevre in and out of the junction
Hint 5: you’ll want to fill the train with two aliens of one colour before doing your first delivery
Hint 1: don’t overthink it: you’re doing four sets of pick-up-two-and-deliver-two
Hint 2: every orange alien will be delivered to their nearest box
Hint 3: every purple alien will be delivered on the way to picking up the next orange alien. The puzzle is about how you use the junctions.
Hint 4: you’ve got more room to manoevere near the entrance than you may remember
Hint 1: the first box you pass by you won’t be filling for a while later
Hint 1: your first pick-up-and-deliver won’t need a wormhole
Hint 2: start by delivering the orange alien near the entrance to the lower of the two orange boxes
Perseus 8 to the same side:
Hint 1: your first pick-up-and-deliver is the same as the solution for going to the opposite side
Hint 2: your second pick-up-and-deliver also won’t need a wormhole
Hint 3: nor will your third
Hint 1: you’ll only use the wormhole once
Hint 2: the first alien you’ll pick up is purple
Hint 3: the second alien you’ll pick up is orange
Hint 1: first delivery is purple
Hint 2: the last delivery will be to the orange box at the top
Hint 3: you use the wormholes twice
Hint 4: it’s easier to manage space around the wormholes if you only enter/exit along one axis
Hint 1: you use the wormholes twice
Hint 2: it’s easier to manage space around the wormholes if you only enter/exit along one axis
Hint 3: first delivery is purple
Hint 4: second delivery is orange
Hint 1: the last two levels have been building you an intuition to prefer only entering/exiting wormholes along one axis. It’s a good heuristic to start from here also.
Hint 1: start by picking up the leftmost orange alien and putting them in the box immediately below them
Hint 2: all three of the orange aliens will each wind up in the box directly adjacent to them
Hint 1: it only looks scary! Remember the train can load and deliver at the same time
Hint 1: the train has three carriages
Hint 1: the area is symmetric around the vertical axis, with each side having two purple boxes and one red. Pick one side of the vertical axis and work on filling the three boxes on that side first.
Hint 1: you need to deliver at least three purples before you can get into the area with the two orange boxes
Hint 2: the last alien you’ll deliver is purple
Hint 3: the last alien you’ll deliver is the purple one in the lower right corner
Hint 4: don’t be afraid to traverse the map horizontally
Hint 5: the purple alien in the upper left will be picked up from above
Hint 6: when it’s finally time to deliver the two orange aliens, you’ll be entering the cluster of boxes from the top
Hint 1: the two green aliens will wind up in the upper two boxes
Hint 1: try working backwards (ie from the exit)
Hint 1: the area is around the vertical axis, with each side having four red boxes, two green aliens, one orange, and one purple. Pick one side of the vertical axis and work on filling the four boxes on that side first.
Hint 1: note you have three columns of space to the right of the boxes
Hint 2: you will use the wormhole three times
Hint 3: one of the times you use the wormhole is to get to the exit after making the orange delivery
Hint 4: when you go from the orange box to the wormhole to the exit, you pass in between where the initial locations of the orange and purple aliens
Hint 1: you do two sets of pick-up-and-deliver
Hint 2: for each pair of orange/purple aliens, you deliver them to the boxes on the *opposite* side of the map
Hint 3: you only need the wormhole twice
Hint 1: you start by picking up a purple alien and delivering them /before/ picking up the orange alien that was beside them
Hint 2: after your last delivery, you will go through the wormhole to get to the exit
Hint 1: you only need to go through the wormhole twice
Hint 1: you only need to go through the wormhole once
Hint 1: you will want to go in between the two purple aliens
Hint 2: the last thing you do is deliver the top right alien to the green box that is closest to the exit
Hint 3: after you deliver the second purple alien, you won’t need to go through the wormhole again
Hint 1: you only need the wormhole twice, so you can block some of the sides
Hint 2: you only need two deliveries (ie. fill the train with all of one colour, deposit them, go after the next colour)
Hint 3: you don’t need the wormhole/junction to get to the first alien you pick up
Hint 1: you will alternate which colours you deliver
Hint 2: you only need the wormhole once
Hint 3: your first pick up is the purple alien nearest the entrance
Hint 4: when you pick up that first purple alien, you do so from below (ie blocking the wormhole from above)
Hint 1: start with picking up the purple alien closest to the exit (bottom-right) and delivering them to the purple box closest the entrance (top-left)
Hint 1: every direction in/out of the junctions will be used
Hint 1: first figure out how to pick up and deliver the two orange aliens before figuring out how/when to do the greens
Hint 2: the last delivery will be orange
Hint 1: the order of pick-ups is purple, green, purple, green, purple, green, purple, green
Hint 1: you will use the wormhole before you need the junction
Hint 2: once you pick up the green alien, you will need to go through the junction to deliver them
Hint 3: after you pick up the first purple alien, you want to go to the wormhole entrance on the *opposite* of the map
Hint 1: remember the train can load and deliver multiple aliens at once
Hint 2: the last box you deliver will be the green one on the top
Hint 3: the second alien you pick up will be green
Hint 1: note there’s a lot of vertical space between the two clusters of box/plant/wormhole
Hint 2: first alien you pick up is green
Hint 3: you’ll go through a wormhole before picking up that first green alien
There are multiple solutions to this one! I know of four of them thanks to this list of solutions.
Hint 1: all solutions I’ve seen end with by getting to the exit from the top of the left wormhole entrance
Hint 2: all solutions I’ve seen also end with delivering to the red and green boxes in the lower right before heading up to the wormhole
Hint 3: if you want to do in four deliveries you’ll need the wormhole three times, but if you do it in in three deliveries you’ll only need the wormhole 1-2 times
Hint 4: don’t assume the red boxes will be filled by the alien colour that is predominant on that side of map
If you go the four-delivery route: (this is what I did)
Hint 5: when you pick up two aliens, don’t assume you’ll deliver both at once
Hint 6: start with using the wormhole to pick up the orange and green aliens in the upper right most corner, then return through the wormhole to deliver them to the green and red boxes in the lower left most corner
Hint 7: the third use of the wormhole is to get to the exit, meaning your last deliveries are the red and green boxes in the lower rightmost corner
Hint 8: when you pick up the purple alien in the upper right most corner with the green alien beside it, deliver only the purple. Green will stick around for a while.
Hint 9: last alien you pick up is purple
If you go the three-delivery route:
Hint 5: you’ll need start by picking up the two innermost aliens (ie the leftmost purple and the rightmost orange) and delivering them
Hint 6: unless you want to pick up the rightmost orange first, you don’t need the wormhole to start by picking up the leftmost purple
Hint 7: work backwards as much as you can
