https://cube4tec.com/simulation/minimal-celtic https://cube4tec.com/media/12613feac91ede3b Minimal Celtic Minimal Celtic is a building simulation in the role of the Celts. A map of Europe leads to the sites. When you enter, the village is already running: farmers, miners, woodcutters and smiths work and carry their goods to the granary, and only there do they count. https://cube4tec.com/media/8896de5bcd7d7dde 33 2026-11-02 https://cube4tec.com/simulation/minimal-city https://cube4tec.com/media/6846abda5d3f82e1 Minimal City The city is alive: people, cars, buses and trains are on the move – around the clock. You steer the whole city with nine City controls in three groups – “City” with Residents, Jobs and New building, “Traffic” with Switch to bus & rail, Traffic lights and Car-free centre, “Public transport” with Buses, Underground frequency and Suburban rail frequency. Residents and jobs are estimated for each building: raise the residents and pavements and roads fill up while living space per head shrinks; with new building the houses visibly grow by up to two storeys; whoever switches to bus and train frees the roads – but trains only have so much room, and the rest wait on the platform. In the “Life & experience” tab you set Shops, Food & drink, Bars & clubs, Culture, Independent scene and Street festivals, or pick “Deserted”, “Normal” or “Lively” straight away: the venues light up in the city, clubs pulse at night, festivals get stage lights and crowds. Every move takes effect at once: the City index sits large at the top – the average of mobility, liveability and experience –, a line below it names the effect compared with the normal day, the same city without controls. On the right the City pulse (key L) shows in three tabs – Effects, Traffic, Life – what lies behind it. In Analysis six lenses – Density, Jobs, Traffic, Crowding, Liveability, Venues – show where it gets dense, full or cramped; hotspots above the city name the places. In the Layers view the city fades out, and below it underground and suburban trains run on the real tracks; in Berlin, Frankfurt and Munich the tram runs as a system of its own. Tap a train or a bus and the camera rides along; a station shows its departure board. Click into the city to see what is going on – say on Invalidenstraße next to Berlin’s main… https://cube4tec.com/media/2aa7bba405bdbd39 30 2026-10-30 https://cube4tec.com/simulation/minimal-factory https://cube4tec.com/media/18273c30367f2b46 Minimal Factory In Minimal Factory you steer 16 real sites in Germany, teeming with activity – on real terrain from official elevation data, built of cuboids in materials such as brick, concrete, sheet metal, rust and paint, with fire, smoke and rolling waves. No order, no rounds: all of them share the same five levers – investment, workforce, supply, quality and market. Every change shows at once output, sales, stockpile and the result per day in euros, plus success from 0 to 100; 10 seconds are one working day. Investment builds out visibly: up to three blast furnaces at the Henrichshütte in Hattingen, as in the 1960s, four lines at Opel-Werk I in Bochum-Laer, three in a future factory after the Mercedes-Benz plant in Düsseldorf, elsewhere coke oven batteries, shafts, washeries, blast furnaces, compressors, quays with cranes, rolling mills, lifts and locks, adits, weaving sheds, ring kilns, container cranes or building docks. Real monuments come to life, the stockpiles fill, and trains, trucks, ships and pipelines run with the volume. When something breaks down at the Henrichshütte, the area flashes red and fitters come. The car plants show production from the inside, from the coil to the first start, the future factory robot cells, driverless transport vehicles, drones and a robot dog; a factory tour travels at eye level from station to station. https://cube4tec.com/media/074330c86cc8f9b8 30 2026-10-30 https://cube4tec.com/simulation/minimal-iga2027 https://cube4tec.com/media/418a57f7c5576353 Minimal IGA2027 MINIMAL IGA2027 shows the five Future Gardens of the International Horticultural Exhibition Ruhr 2027 as a schematic block world on real elevation data and OpenStreetMap. https://cube4tec.com/media/be91a07be7f12509 32 2026-11-01 https://cube4tec.com/simulation/minimal-mall https://cube4tec.com/media/c188e7074ced55a0 Minimal Mall Minimal Mall shows how a shopping centre works: cars look for spaces, buses and trains bring people, shops sell. Everyone on the move is out shopping – those leaving carry bags. Sales today sit at the top; the ring shows sales per hour against a normal day. https://cube4tec.com/media/ad88388b322962bc 30 2026-11-01 https://cube4tec.com/simulation/minimal-mine https://cube4tec.com/media/799e28af278db27c Minimal Mine “Colliery at work” opens Zollverein as a city underground, first in “Section”: the headframe stands at the top of the cut edge, the shaft runs down it. ‹ › leafs through the 21 researched collieries, and no two are alike. Their workings follow the research: levels at their real depths, shafts by purpose, seams lying flat or steep, major faults, central shaft sites and links to neighbouring collieries; above, their surroundings from OpenStreetMap with real heights. Everywhere there is work: cages and skips run, locomotive trains shuttle to the pit bottom, ploughs and belts bring the coal out of the longwalls, miners arrive for the change of shift, fresh air flows in bright, return air leaves warm. In “Surface” the coal carries on through screening and washery onto the heaps, into the colliery railway, the coking plant or harbour. Underground you pick all or just levels, faces, coal, air or water; on the surface and in the section the cubes cast shadows. Six controls – Miners, Longwalls, Trains, Shaft, Ventilation, Pumps – set the operation, calculated from the colliery’s data. Leave the controls alone and the camera tour takes over. Fan, sheaves, trains, longwall, belt and pump sound where they are. https://cube4tec.com/media/b841542fbadad15b 30 2026-10-30 https://cube4tec.com/simulation/minimal-space https://cube4tec.com/media/fe34822f74118726 Minimal Space Minimal Space starts at the Earth: a globe you can turn, with clouds, day and night sides in front of a starry sky with the real bright stars, launch sites and a timeline of spaceflight. On the Apollo 11 card you can fly the 1969 Moon landing yourself, the last 150 metres on scarce fuel to a clear spot. A factual account follows. https://cube4tec.com/media/8a85b9f25beba10c 56 2026-11-04 https://cube4tec.com/simulation/minimal-water https://cube4tec.com/media/74f376cb9a1cdf7e Minimal Water “Start” opens the water cycle: at the bottom three big levers – Rain, Heat, Consumption – and four weather presets that set them with one tap. The landscape shows what they do: in good times the houses are bright, fields bloom, flocks of birds cross the forest. In a drought fields wither, trees die, the river turns narrow and warm, dead fish drift, the reservoir dries out from the shore; dry forest can catch fire. When the town runs short of water, whole neighbourhoods fade, houses stand empty and decay. Lots of rain brings floods and overflowing sewers. At the top sit water in town, storage and five values, and signs on the map mark where things happen; tap to fly there. On the right a small wheel, at the bottom a subtitle explaining what is happening. Trees of trunk and crown sway in the wind; dead ones leave grey trunks, burnt ones black, and fields have rows. With rain the land recovers, a dead forest does not. For specialists the “Control room – for experts” remains. https://cube4tec.com/media/d83aebde2ba559a2 30 2026-10-30 https://cube4tec.com/simulation/minimal-organization/amtsgericht

Battle staff and Hammer lie waiting as loot; you also charge the shockwave and pick upgrades such as Chain pulse or Double wave. https://cube4tec.com/media/5d899e68fae1c8ba 30 2026-10-30 https://cube4tec.com/games/minimal-raid https://cube4tec.com/media/6ad9b46a08539ee9 Minimal Raid You fly over the City, the Ocean, the Desert and through the Canyon – landscapes of cubes in clear sunlight and real water with waves, surf and white water. Enemies in grey and olive with red markings: jets, drones, helicopters, tank columns, missile trucks, flak and patrol boats, plus steampunk zeppelins, air cruisers and warships. Crates on parachutes bring the Laser, Spread shot or Cannon, plus Missiles, Bombs, Drone and Shield – visible on your ship. You shoot down whole formations – they go up in seething fireballs and clouds of smoke that cast shadows – and trigger the Break when it is ready. Along the way the bosses Colossus, Ringwork and Core are waiting. https://cube4tec.com/media/1c0bacf6302f4769 30 2026-10-30 https://cube4tec.com/games/minimal-run https://cube4tec.com/media/8f6a8357cc1ef593 Minimal Run You steer a cube through the lanes of a world made of thousands of blocks; it casts a halo of light in its colour. Press down every lane before it grows back, hunt the seekers and let your snake grow. Once a world is cleared, the portal opens – and the world morphs before your eyes into the next one. https://cube4tec.com/media/5b0c52fc7aa32148 30 2026-10-29 https://cube4tec.com/games/minimal-tower https://cube4tec.com/media/83e6f34a6e903f04 Minimal Tower Defense Enemies come over roads, rivers and through the air, heading for your core. You build towers in a real landscape, and height matters: the higher a tower stands, the further it shoots. https://cube4tec.com/media/035de9cd2b2d2994 30 2026-11-02 https://cube4tec.com/games/minimal-volume https://cube4tec.com/media/1f9bfa6a40455d94 Minimal Volume The pieces don’t fall into a well but into a volume: you turn, tip and roll them on three axes and close whole layers. Each piece appears well above the volume, leaving time to turn it; with “Stop” it waits until you drop it. The keys are shown right at the piece, and the X-ray marks hidden gaps in red. All around, the light is alive: the falling piece glows in its colour and tints the stack beneath it, the lamps on the columns answer the music, a light grid stretches to the horizon. When a piece locks, a wave runs across the square; when a layer fills, a column of light rises and a shock wave passes through the image. And again and again one of twelve events appears: shooting stars, searchlights, fireworks, a thunderstorm, a light train circling the square, columns jumping like dominoes, northern lights or a lighthouse. https://cube4tec.com/media/40e0b294512d177d 30 2026-10-30 https://cube4tec.com/videos/agile-bingo https://cube4tec.com/media/546171e6ab3b56ee AGILE BINGO What experiences have you had around agile? https://cube4tec.com/media/712a844660871e26 260 2023-04-28 https://cube4tec.com/videos/das-ewige-murmeltier-make-or-buy https://cube4tec.com/media/fd62144091423b53 THE ETERNAL GROUNDHOG: MAKE OR BUY How do you decide between buying and building yourself? https://cube4tec.com/media/7006ef719ac06721 337 2023-04-28 https://cube4tec.com/videos/das-pflichtenheft-ist-kein-bauplan https://cube4tec.com/media/d8771e20869f2cf7 A SPECIFICATION IS NOT A BLUEPRINT A requirements document brings a great many problems with it. https://cube4tec.com/media/4eff28292710817d 344 2023-04-28 https://cube4tec.com/videos/das-unbekannte-wesen-softwareentwicklung https://cube4tec.com/media/8362d5ad4ca8ec59 SOFTWARE DEVELOPMENT, THAT UNKNOWN CREATURE What is software development to you? https://cube4tec.com/media/df76dbf861abd524 359 2023-04-28 https://cube4tec.com/videos/der-heilige-gral-in-der-technikwahl https://cube4tec.com/media/e26e2137b0548d6c THE HOLY GRAIL OF CHOOSING TECHNOLOGY The debate about the best technology is open. https://cube4tec.com/media/9de8fbe1a7bafafe 388 2023-04-28 https://cube4tec.com/videos/die-bruecke-als-metapher-fuer-den-kritischen-pfad https://cube4tec.com/media/8c98a98cd6aa2260 THE BRIDGE AS A METAPHOR FOR THE CRITICAL PATH Which metaphors do you use to make a software project vivid? https://cube4tec.com/media/d419d1117911cc9d 222 2023-04-28 https://cube4tec.com/videos/die-entwicklerkatze-im-sack https://cube4tec.com/media/6c8cef9b58d6e928 BUYING A DEVELOPER SIGHT UNSEEN How do you find the right developer for your project? https://cube4tec.com/media/8fe8f9d331a8f1a4 311 2023-04-28 https://cube4tec.com/videos/die-grosse-glaskugel-aufwandsschaetzung https://cube4tec.com/media/7135462671b39275 THE GREAT CRYSTAL BALL: ESTIMATING EFFORT Perhaps the hardest subject of all to convey in software development. https://cube4tec.com/media/c623b3c020cde2c7 526 2023-04-28 https://cube4tec.com/videos/kein-sandwich-ohne-eier https://cube4tec.com/media/cdb313aa2f30c07b NO SANDWICH WITHOUT EGGS How do you fare as a project manager in that particular role of yours? https://cube4tec.com/media/64e74277503f9230 277 2023-04-28 https://cube4tec.com/videos/kreativitaet-ist-der-motor https://cube4tec.com/media/b7dcc8c1e10f376a CREATIVITY IS THE ENGINE Sometimes it simply takes a new awareness. https://cube4tec.com/media/d0bb5bfae4259d75 270 2023-04-28 https://cube4tec.com/videos/lieblingsthema-technische-schulden https://cube4tec.com/media/96f265df393e5a15 FAVOURITE SUBJECT: TECHNICAL DEBT How do you avoid technical debt? https://cube4tec.com/media/0423e2aa83958736 494 2023-04-28 https://cube4tec.com/videos/toxic-requirements https://cube4tec.com/media/5db78a85ddbeb6a1 Toxic requirements How do I avoid dangerous risks in software projects?
