Infinifactory

Already extremely repetitive in level 9 and mouse acceleration is ignored.

Another great Zachtronics game! This is the real deal... these puzzles get complicated fast, and you are building in three dimensions. Gadgets get unlocked as you progress, and the number of inputs pieces you must move on belts, glue together, grind into dust, rotate, alter, and otherwise manipulate increases too. There are sensors that allow you to change the state of gadgets, connected with piping. Everything exists within a cube of a specific size (sort of like Minecraft), and there are interactivity rules between them to learn. Often, things can get quite tricky... and very satisfying when you nail a head-scratcher. Some puzzles require you to assemble something from the given parts in a specific configuration, then convey your results -- via conveyor belt -- to an output. Other puzzles have an assembly line with a product (such as a tank or a computer desk) that must be changed somehow, before it reaches the end of the line... and it must be done before the next one ...

Tis good.

An underrated gem. Being an automation puzzle, there are multiple ways to set up your pipeline and there is no pressure to always have the most optimal solution. That way you can have a lot of fun just making your own solution and watching it all come together. But the most fun you can have is in figuring out the most optimized solution. The game encourages you to think out of the box by comparing your solution to the community in 3 categories, Number of Cycles, Footprint and Blocks. Let's say if you have solved a puzzle with about 15 blocks and think its good, there might be someone else who did it in 14 or less and you would have your head scratching and it's fun to redo it and get to the optimized solution. This makes Infinifactory one of the best puzzle games to develop logic.
