Three collapsed catapults before anything works, then a hundred hours of tinkering. A physics sandbox that teaches by failure and rewards anyone willing to build ugly first.

My first three machines came apart before they reached the target, and the fourth flipped end over end because I bolted a cannon to the wrong side of the centre of mass. That first hour is the entire argument against this game, and pushing through it is the entire argument for it. There is no tutorial in the way strategy players expect one, no tooltip explaining torque or how far a wooden brace bends before it snaps. What you get is a grid, a block palette, a key-binding menu, and a windmill you are supposed to knock over. The learning happens in the failure log. If you need structured onboarding, this will feel hostile for about ninety minutes. If you have ever spent an evening working out why your economy stalls on turn 40, you already have the right instincts for it. Mechanically it is a construction sandbox with hard constraints. You assemble contraptions from wooden blocks, wheels, hinges, springs, ropes, balloons, cannons, bombs and flamethrowers, then bind every moving part to a key so you can drive the thing yourself. The campaign runs across island regions, each with a handful of objectives: flatten a structure, clear a garrison, haul a payload from one marker to another, survive a defensive gauntlet. The objectives are simple to read and brutal to satisfy, because the simulation does not care about your intent. Joints have real stress limits. Weight distribution decides whether your ballista platform fires or somersaults. Each level is a constraint puzzle where the constraint is physics and the solution space is genuinely enormous. Here is the case for treating a hundred-hour tinkering game as a beginner-friendly purchase, because approach matters more than hours. Do not open with the leaderboards. Do not open with a Workshop download either, since reverse-engineering somebody else's forty-block walker teaches you nothing in week one. Build ugly. Get a four-wheel chassis with a steering block that survives a bumpy approach, then keep that chassis and bolt different weapons onto it for the next six levels. That is your build order. By the time the campaign starts demanding flight, grabbing arms or precise long-range delivery, you will carry four or five reusable subassemblies in your head and the curve flattens hard. The players who bounce off are almost always the ones who tried to design a bespoke solution for every level from scratch. The naval content is where this edition earns its name, and it is more than a reskin. Water adds buoyancy and drag plus a completely different failure mode: your machine does not explode, it slowly capsizes while you watch, which is somehow worse. Hull shape, ballast placement and propulsion mounting all start to matter, and the intuition does not transfer cleanly from land vehicles. That arrives at a useful moment, roughly when the ground-based puzzles stop surprising you. Around all of it sits the support structure that keeps a sandbox alive for years: a level editor, heavy Steam Workshop integration, leaderboards, and multiplayer covering co-op building as well as PvP over online and LAN. The mod ecosystem is the real long tail, particularly the logic and automation mods that expand what is buildable at all. Where it disappoints: the trial-and-error tax is real and the game does little to reduce it. There is no in-game reference sheet listing a block's mass, strength or power output, so you learn the numbers by crashing into them instead of reading them. Part counts punish ambition, and a sufficiently elaborate machine will drag the simulation down on hardware that runs everything else fine. Campaign objectives recycle their patterns more than they should. Multiplayer is a pleasant novelty rather than a mode with real structure behind it. And that 95 percent approval across more than fifty thousand reviews reflects the people who stayed, not the ones who quit after the fourth windmill. Go in expecting a workbench rather than a campaign and it is one of the most generous sandboxes on PC. Diego, Scout Team

Best for tinkerers who enjoy debugging their own bad ideas; skip it if you want a tutorial to hold your hand.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
