Solomon's Key is a classic NES puzzler that'll still test your brain today. It's all about finding hidden keys, creating and destroying blocks, and figuring out the right order to tackle each room. The controls are a little stiff and the difficulty ramps up fast, which can get frustrating. But, if you love a good brain-teaser with charming retro graphics, Solomon's Key is worth checking out, especially if you're a fan of old-school challenge.
