Contraption Maker

What the game is

Contraption Maker was released in July 2014 by Kevin Ryan, the designer and programmer of The Incredible Machine, working with the studio Spotkin. It runs on Windows, macOS and Linux and is the direct successor to that 1990s series rather than an imitation of it.

The screen is a flat, brightly drawn side view, like a cartoon cross-section of a room or a hillside, with a tray of parts along one edge. You drag parts in and drop them where you want. More than two hundred official puzzles ship with the game and over a thousand more come from other players. Each puzzle takes a few minutes, which makes it one of the few games in this part of the catalog that fits comfortably into half an hour. There is also a free-build Maker Lab where up to eight people can construct something together online, and a JavaScript editor for players who want to script their own puzzle types.

What you actually do

You read the goal, look at what is already placed, and work out what is missing. A ball needs to reach a basket, but the ramp is too short, so you add a trampoline; the trampoline needs the ball to arrive faster, so you raise the starting shelf. Press start and the whole machine runs at once, which means a single wrong angle spoils everything and you have to watch carefully to see where it went wrong. Later puzzles supply more parts than you need and several plausible routes, so the work shifts from finding the one answer to choosing between them.

What it exercises

• Builds a sequence of causes that reliably produces a wanted result
• Predicts where a rolling or falling object will end up
• Spots the exact step where a chain reaction broke down
• Uses simple machines such as ramps, pulleys, belts and levers on purpose
• Designs a puzzle for someone else and tests that it is solvable

Why we rate it Low Worksheet score 53 / 100

1. FitHow much real knowledge or skill does the play itself make you use?55weight 45%

   Scored 55. Arranging causes so they fire in the right order is the entire game, and a puzzle only counts as solved when the whole chain runs without help. That is a genuine narrow skill worked directly, which is why it clears the moderate line, but the parts obey comic rules rather than real mechanics, so there is no wider domain underneath the sequencing.

2. TransferWill what you practise here work outside the game?45weight 30%

   Scored 45. Building and debugging a sequence is a genuinely valuable habit at eight, and the game asks for it constantly. The physics itself does not travel, because balloons, mice and treadmills obey comic rules rather than mechanical ones, so what carries over is a way of thinking about order, not knowledge of how machines actually work.

3. PracticeDoes the game make you use that skill again and again, as it gets harder?60weight 25%

   Scored 60. Two hundred official puzzles plus a library of more than a thousand player-made ones reuse the same reasoning many times over, and designing puzzles for other people extends the practice further. It stays in the middle because the difficulty curve is gentler than in heavier puzzle games, so the challenge plateaus well before the content runs out.

What the evidence says

Editorial onlyNobody outside our desk has checked this. It is our reading of how the game plays.

This is Editorial only. The sources are the developer's site and the Steam listing, checked on 10 September 2026. They confirm the designer's connection to The Incredible Machine, the two hundred official puzzles and the thousand-plus player-made ones, the eight-player Maker Lab, the JavaScript editor and the review figure quoted above. No educational claim is made on either page and no study of the game exists that we could cite. This assessment rests on the observation that arranging and debugging a chain of causes is the only activity the game contains.
