Play Matematik i Måneby

Play it right in your browser. No installation, no CD-ROM drive.

Good to know

• The game is played with the mouse. A few tasks use the arrow keys and the space bar.
• On this page the game starts in English. Choose another language with the flags at the bottom of Setup: Danish, English, Swedish, Norwegian Bokmål and Nynorsk. Your choice is remembered as long as you open the game from the English page; the language menu at the top also changes the game's language.
• The English version was never released, and its speech is incomplete. Some tasks are read aloud in Danish, and some have no speech.
• The wise old man reads the texts aloud. Click on him if a task is giving you trouble.
• Press Esc on the town map and choose Save. The game is saved in the browser on this computer. On a shared school computer or Chromebook, also press Download a copy, and next time open the file again under Load game. A saved game with the same name is overwritten, so use different names, for example Anna B.
• Teachers can read more under For teachers.
• If something looks wrong, let us know.
• If the game does not start on a school computer, there is a guide for IT staff.

Fixes in the game

The game runs as it was released in 2005. A few things are not original, though, because they had to be changed:

• Valley of the Smoking Mountain: if you left the task while the claw was falling into the lava, the game remembered it, and the next time the crane started without its claw. The bug is on the CD-ROM too. Here the game's own script has been fixed so that it is reset every time the task starts.
• The fire station: in the original web version, the first press of Esc only stopped the sound, and you had to press it again to get out. Here the game's own script has been fixed so that a single press leaves the task, just as in the other tasks.
• The fire station: in the original web version, the task never moved on once the last stone had been sorted, and the conveyor belts just sat there empty. The only way out was Esc, which threw the result away. Here the game's own script has been fixed so that you return to the map with your result, just as in the other tasks.
• The kitchen: in the original web version you could briefly see the end scene, where the cook serves the food to the workers, right after the wise man's introduction while the kitchen itself was loading. Now the introduction waits for the kitchen, as it does on the CD-ROM.
• The stalactite cave and the power station: if you held an arrow key down after the miner had reached the edge, the game kept counting, and the opposite key had to be held just as long before he would move again. It was like that on the CD-ROM too. Here the game's own script has been fixed so that the arrow key stops at the edge and the opposite one works straight away.
• The English version is switched on. The translation is on the disc, but the flag was hidden because that version was never released. It was never quite finished: part of the voice-over is missing, so some tasks are not read aloud in English. A few spelling mistakes in the game's own texts have also been corrected.
• The asphalt road in English: the game's text says 100 pounds of asphalt for every foot of road, but the answer was checked against double that, so the right answer was always counted as wrong, and the longest roads could not be solved at all. The English version never came out on CD-ROM, so the mistake was not found at the time. Here the game's own script has been fixed so that the check follows the text. The other languages are unchanged.
• The asteroid belt in Norwegian and Nynorsk: the task text said the ship can only take stones under a quarter, a third, two thirds or three quarters of a ton, but the game counted with one and a quarter and so on, as the Danish and Swedish texts say. It was like that on the CD-ROM too. The text has been corrected so that it matches the task.
• The copy here is an evaluation disc, which would otherwise show a notice about a trial period in every task. One of the game's creators has given permission for it to be here free of charge for now, so the notice and the licence lines are hidden.
• Setup (grade and topics) is remembered in the browser. On the CD-ROM it only lasted until the program was closed, and here it would have been forgotten at every reload. A saved game still has its own settings. A teacher can also share a link with ?klassetrin=3 (1 to 6), which starts the game in that grade with its topics. This is done in the game's own script.
• On a phone or tablet, tapping the name field now opens the on-screen keyboard so you can type your name. The game was made for computers with a keyboard.
• On a tablet without a keyboard there is now a Menu button beside the game. It does the same as the Esc key: it opens the menu where you can save and quit, and it leaves a task. The game was made for computers with a keyboard, so without the button you could neither save nor get out of a task.
• The files have been made smaller to download: the sound has been re-encoded in a newer format, and resources the game stored several times over are shared. The sound's level and length have been measured against the original.

Quirks of the original

Some things feel off, but that is how the game was on the CD-ROM as well. We have checked them in the game's own code and are leaving them as they are:

• The desert plains: the car can hit a stone it does not touch, because the game uses square boxes around the figures.
• The desert plains: changing a tyre after a collision can take more than ten seconds.
• The stalactite cave: the ball only counts as a hit when its centre is over the helmet, so it can slide past the edge.
• The fire station: if you click a piston several times, the game remembers every click, and the piston keeps pushing, once for each click.
