Crazy Machines 3 is a legitimately good physics puzzle game that sneaks STEM learning into genuinely fun gameplay. The premise—build ridiculous contraptions using lasers, bombs, floating objects, and cartoon physics—hits that sweet spot between silly and smart.

The creative freedom is the real star here. Kids aren't just solving pre-made puzzles; they're designing their own machines, experimenting with materials, and sharing creations. That's the kind of open-ended play that actually develops engineering thinking.

The 2016 release date shows a bit in the graphics and UI, but the core mechanics hold up well. Reviews consistently praise the physics system and level design. No monetization garbage, no chat toxicity, just pure puzzle-solving.

If your kid is the type who takes apart electronics or builds elaborate domino runs, this is their jam. It's not flashy or trendy, but it's solid, safe, and genuinely enriching.
