Super Mario Bros Boat Bonanza is one of those weird little Flash games that somehow sticks with you. You're steering Mario in this rickety boat, trying to scoop up coins while dodging piranhas that leap out of the water—seriously, they come out of nowhere sometimes. The skeleton birds are annoying because they swoop in unpredictable patterns, and those bomb balloons? Yeah, don't even get me started. Green mushrooms give you an extra hit, which you'll definitely need.

It's simple but weirdly tense—you think you're doing fine until three enemies gang up on you at once. The boat controls take a second to get used to, but once it clicks, you'll be weaving through obstacles like a pro. Just don't expect it to go easy on you.
