As a personal project I recreated a mini game from Brain Age DS. It took me about a week to complete and I'm pretty happy with how it turned out. I recreated all assets, used royalty free resources and used numerous videos as reference to get the game as close as possible to the original. You can play it in three different difficulty modes and the game lasts for 5 turns. The game is available in HTML5 and you can play it for free. The original design and all original copyright belongs to Nintendo.
