Play Mario Vs. Donkey Kong Online

I first played Mario vs. Donkey Kong on the Game Boy Advance back when it was new. It was developed by Nintendo and felt like a natural fit for the handheld, a puzzle platformer that took the old Donkey Kong arcade rivalry and built something new from it. The GBA had a lot of side scrollers, but this one stood out because of its focus on thinking your way through levels rather than just running and jumping.

You control Mario across a series of single screen stages. Your main goal is to retrieve a key and then carry it to a locked door, all while avoiding or outsmarting Donkey Kong and various enemies. The signature mechanics involve precise platforming and manipulating the environment; you often have to flip switches, ride moving platforms, and use temporary items like springs to reach high places. The game is methodical, requiring you to plan your route before you move, and the difficulty ramps up steadily as new hazards are introduced. It feels satisfying to finally solve a tricky room after a few failed attempts.
