Well, this will be the next incomplete explanation for a while. -162.158.90.165 21:58, 24 November 2015 (UTC)

Yes, one thing to note is how to get the hell out of the cave near the volcano 108.162.249.159 22:38, 24 November 2015 (UTC)

The image is made up of small images with addresses of the form http://xkcd.com/1608/XXXX:-YYYY+s.png (although not every coordinate inside the bounds has an image associated). A script could probably dump out all the images and paste them together. --108.162.216.6 22:46, 24 November 2015 (UTC)

West -- Under Lava Pools -- Elon Musk's Secret Volcano Base (not as enjoyable as you might expect).

The Starship out east contains, among other things, Darth Vader, apparently explaining Steven Universe to a subordinate. (Steven and the Crystal Gems can be found a the west end of the ship, near an ice cream cooler.) The same ship contains an elaborate homage to the original Prince of Persia. 162.158.56.5 (talk) (please sign your comments with ~~~~)

There, have at thee an image! Arch-TK (talk) 22:58, 24 November 2015 (UTC)

There are 168 coins spread throughout the map according to the source code 173.245.54.53 23:03, 24 November 2015 (UTC)

When using a device, instead of saying "use arrow keys to move", it says "tilt to move, tap to jump". It's also a lot harder to control. 108.162.250.159 (talk) (please sign your comments with ~~~~)

It's actually 169 coins (t.length). --188.114.111.129 23:22, 24 November 2015 (UTC)

I got 153 coins!! :D There's two starships, one's a star destroyer with an expansive maze dropping regular torpedoes on the other. May be noteworthy that there are various references to Star Wars and Steven Universe throughout. 108.162.221.13 23:27, 24 November 2015 (UTC)

The second starship is the TantiveIV, Leia's ship at the beginning of episode 4. Note directly below the Tantive, the terrain seems to be sand dunes. Also there are two more space ships by the volcano; an X-wing at a gas station and an Apollo Command Module. 108.162.216.24 (talk) (please sign your comments with ~~~~)

https://xkcd.com/1608/tigl.js - Looks like there's an easier to read version of the code there. Maybe that'll help someone with extracting all the images. {{unsigned ip|

I've got all the images downloaded. Zipping/uploading now. Should I post a link here when complete or what's the best way to share these? I'm also working on setting up a zoomable map. 173.245.54.53 23:57, 24 November 2015 (UTC)

The collision detection is glitchy. I keep landing/bumping against platforms I'm far away from. Is getting stuck against walls normal? --199.27.130.234 00:01, 25 November 2015 (UTC)

Tiles are located here in a zip: https://up1.ca/#Gi51KPFyPRELe0T1D6q9Mw All I did was iterate over http://xkcd.com/1608/X:-Y+s.png from X=[916...1116] and Y=[916...1116]. I'm working on putting a zoomable map together. If anyone has interest in helping we could hop on IRC? Jcox (talk) 00:15, 25 November 2015 (UTC)

I've written a zsh script to iterate over all possible tiles (does anyone know the height limits? the source only gives the left and right limits) and glue them together into one giant file. I'll upload the results as soon as it's finished. Arch-TK (talk) 00:17, 25 November 2015 (UTC)

I don't think it's limited vertically at all. I found a zoomable map on the reddit topic http://codepen.io/KyleDavidE/full/605dc87b614ff6b2bd716f4c6f640203/ (by kyledavide) Miraries (talk) 00:21, 25 November 2015 (UTC)Mirages

Alright, the full png of the entire map is almost finished, I should have used white tiles as blank tiles but I guess I can fix that up in gimp, and I'm not sure how to account for the 1 pixel overlap with just imagemagick convert. The last step is to merge allthe layer images into one giant image, wish my laptop the best of luck! Arch-TK (talk) 01:00, 25 November 2015 (UTC)

Someone beat you to it, but keep on it: that one doesn't have right limit tiles. https://www.reddit.com/r/xkcd/comments/3u4sy1/xkcd_1608_hoverboard/cxc0p8x --188.114.111.129 01:19, 25 November 2015 (UTC)

Perhaps we can change the screenshot at the top to this? It's a quickly hacked overview of the entire map: http://imgur.com/Mz9arHz 199.27.129.167 01:27, 25 November 2015 (UTC)

I think it might make more sense to just add it as another image, mediawiki supports this after all. The syntax should be: [[File:filename.png|thumb|Subtitle|alt=alt]] Arch-TK (talk) 01:34, 25 November 2015 (UTC)

I wrote a tampermonkey script that shows you your coordinates and lets you teleport; will make coordinate sharing a lot easier. You do need tampermonkey installed for this to work. Click to install Minerguy31 (talk) 04:17, 25 November 2015 (UTC)

I got 159 coins without the map. If you guys are still wondering how to escape the volcano, move to the right for as long as you think you can, then start spamming the up key while switching between holding the left and right keys. It worked for me on my first try.162.158.252.119 07:06, 25 November 2015 (UTC)

Didn't take down the coordinates, but the layout to the first level of the original Prince of Persia is in there, including the guard standing by with his scimitar! I found it in the ship atop the pyramid east of the play area. --108.162.218.245 06:24, 25 November 2015 (UTC)

Just thought this was interesting, when you "complete" the game by dropping coins, the following line of javascript is run, which sends your result to the server (L is number of coins, z is seconds used): (new Image).src = "//xkcd.com/events.gif?coins=" + L + "&seconds=" + z; Don't be tricked by the .gif extension, it doesn't show an image when opened, and the server probably handles this request by logging it to somewhere. 141.101.80.87 (talk) (please sign your comments with ~~~~)

It actually returns a 1 by 1 pixel white GIF. Arch-TK (talk) 13:14, 25 November 2015 (UTC)

Is there a way that we can merge the "game" part of this comic with the map of 1110: Click and Drag? Allowing us to explore that one in a similar way? Bon (talk) 11:03, 25 November 2015 (UTC)

Well I managed to find (nearly) everything, except the floating rock island, and 162 coins without the map, but even with looking at several maps, I didn't pass any graveyard nor found the way to the grey ocean, which I assume is underneath the "continent". Does anyone know where the entrance is? 162.158.90.218 11:54, 25 November 2015 (UTC)

Just thought I should say; the comic supports some alternative movement controls, there's the arrow keys, WASD, and also the vi keys (hjkl), and the numpad (8426). 108.162.242.125 13:29, 25 November 2015 (UTC)

I was not able to get to some points because they were surrounded by text, people or other objects. Is that normal, or are there tricks to get to every coin without using cheats (console)? It would be nice if this could be mention / explained in the article. 162.158.135.35 13:31, 25 November 2015 (UTC)

In some cases you can come in from the side as opposed to trying to come down through or up through something. Example: at the X-Wing "gas station", to get that coin, land on the ground to the left of the X-Wing and move to the right on the ground towards the gas station. Jarod997 (talk) 14:45, 25 November 2015 (UTC)

The list of "areas" in the map would be much easier to read, and much easier to correlate with the map, if the origin were set to the starting area (that is, if the coordinates of the starting area were set to x:0, y:0). What is the reason for the very large numbers? --BlueMoonlet (talk) 15:50, 25 November 2015 (UTC)

The large numbers are the actual ones used by the game code and displayed by the hacked-up "radar" so it was a natural choice to use them as they are. We could define some origin and count coordinates from it but we would have to agree on its position and then change the "radar" code and recalculate all coordinates written down already. -- 162.158.90.224 08:53, 27 November 2015 (UTC)

The starting area is in no way related to pac-man. The lines are not all right angles, there is a timer, there's gravity, there are no aggressors, you're collecting coins instead of pellets.... Not every line maze is pac-man. This is an erroneous reference that should be removed. --198.41.235.167 17:16, 25 November 2015 (UTC)

The source code found at https://xkcd.com/1608/tigl.js does not seem to be complete. I would personally work on de-obfuscating the full source code using the fragment found there but technically the source is covered by implicit copyright laws and that means that if I published a derived work I would be breaking those laws. Should I just change the line from "The source code can be found at ..." to "The full (obfuscated) source code can be found at ...tigl.min.js and a deobfuscated piece of the source code can be found at ...tigl.js".

I added quick coordinate / teleport access on right-click to the quick hack map. Kyledavide (talk) 20:45, 25 November 2015 (UTC)

Can't be bothered working out how to edit the page, but the explanation contains the phrase "People holding anchor lines to a Star Destroyer" - they're holding anchor lines to a CR90 Corvette, specifically the Tantive IV, commonly referred to as the "Rebel Blockade Runner", which in turn is being *attacked by* a Star Destroyer.

I slightly improved the "direction to next coin"-code by displaying a compas. Code can be found here http://pastebin.com/PL6fv5XK . I'm new to this wiki and don't want to mess up the page, so I didn't put the code in there myself ... --162.158.90.209 00:01, 26 November 2015 (UTC)

Haven't read all the comments above so maybe someone has written about it? If you click up it seems to count how many times. So it will just show white and then when you release again, it will take longer to hit the ground the longer you have pushed up. Tried with 100 clicks (9-10 seconds) and 200 clicks (20 seconds). I got about 163 coins in about 15886 seconds. (4 hours and 24 minutes.) That was with breaks. It was written so shortly on the screen I did not manage to take it down for certain. But after that I read here about the 169 and found that there where at least three in the volcano I had not noticed at first. And it seems likely that there would be three more I have missed. But really fun to explore. I wrote a lot of the transcript along the way (not from the very start though) This I have now posted without any real order in the 1608: Hoverboard/Transcript page. Hope fully a full and useful transcript can emerge from this. I hope my text can be used if not used as it is written at the moment.--Kynde (talk) 02:05, 26 November 2015 (UTC)

Just added in the 'collision detection' section the text "On a slow connection, it's possible to move into an 'open' area and then the black image loads in and (probably permanently, without tricks) traps you immobile." To expand upon this, if this is a risk to anyone else (I'm reliant on mobile internet, being away from any comparable landline capability) then you need to look out for perfectly horizontal/vertical edges. For example, hovering up the side of the Washington monument and encountering (typically above the 'bricks' line) a completely flat top. Drifting onto that soon gets you embedded in the remaining Monument, somewhere well below the eventual tip. Alternately, drifting sideways over the landscape and discovering a perfectly vertical cliff downwards (just past the bowling pins is a prime location) tempts you to drift down it and then suddenly the solid land 'happens' around you, forcing a page-refresh and restart (though doubtless there's also various console tricks that could be used). The well, also 'opens out', but it's a lie. I've ended up trapped 'in white' below the now closed black blocks that surround the well bottom (and not found any way back up). But if there a 'texture' (like other cliffs) or 'slope' (like the real Monument edge) to the surface, you're probably Ok. It's a genuine surface or wall that you can generally navigate around without fear of being misled. (Or so is my experience.) 162.158.152.227 09:12, 26 November 2015 (UTC)

I agree with Arch-TK. I have changed the text referring to the source code, since it does not refer to the full sourde code, but just an obfuscated part.--Gamevang (talk) 14:36, 26 November 2015 (UTC)

I can't pass through text, anybody else experiencing this? I remember being able to pass through text without no clip mode earlier, but for some reason not anymore.--173.245.54.36 18:16, 26 November 2015 (UTC)

We definitely need a better presentation of interesting objects/locations and their coordinates. Now, we have quite comprehensive multi-level bullet list and a newly-started table. Neither is perfect. We need some form that will show clearly what is where and where it belongs.

Issues to solve:

• Many objects are large and a single coordinates pair simply don't describe them well. We need a clear presentation form that will allow putting both a single pair and several ones, e.g. top and bottom for thin vertical objects (e.g. poles, The Monument), four corners for objects occupying large swaths etc.
• Grouping - we need to group objects that belong to an area, like all things within the Star Destroyer etc. Multilevel bullets are ok, but how to do that in a table?
• Order - within groups and between them, we need some ordering that will organize the entries. For example left-to-right then top-to-bottom or something like that.
• Coordinates system - the "native" game coordinates are large numbers, and negative values for the y coordinate to boot. Someone proposed setting a new origin and counting from there. I think it's a good idea, but will require a firm decision, rewrite of radar code and recalculating of all coordinates written down so far.

Any ideas? -- 162.158.90.224 09:24, 27 November 2015 (UTC)

If it weren't for so much effort put in already, I think that we could re-class features as follows:

• All coin locations, and/or links to the locations they are associated with (e.g. "in original game area" and "carried by a quadcopter drone"), if that's not considered 'unfair' to those wanting to actually play the game (without the self-discipline not to browse the list ;).
• Locations of all characters, certainly all stick-figures, but maybe also 'wildlife' (or automata) of notable types.
• All monologues/dialogues/labels (albeit that this is almost entirely a subset of the prior list).
• Other notable landscape (or structural) features that are more than mere 'flavour' (e.g. the T-shaped mushrooms/whatevers to the east, but not random ground-boulders).
• Notable move-through spots; inclusive of 'sink-into'able waters/magmas (waist-height, neck-height, fully-submerged?), even when not featuring further hidden routes, but excluding vegetation (ground-grasses/tree-trunks) that mostly are pass-throughable.

Some of these are themselves useful references to other items (e.g. "inside front of Blockade Runner" or "beneath eastern stretch of magma") and so can probably be sub-grouped as all items in a given structure ("coins within the initial play area", "characters/speech within the Star Destroyer") and some things do occupy a swathe (the 'play area', the Monument, the ships, the kites, with their strings; the hail of (regular) torpedoes). And I bet there's a whole lot of arguments about what level of detail we could go to... 162.158.152.227 10:21, 27 November 2015 (UTC)
