Tacoyaki is a puzzle game where your goal is to change all the markers on the board into a single color. This can be done by flipping the markers on the board, but it's not that simple. Every time you flip a single marker, all the markers diagonal to it across the board (imagine a huge X shape with the marker you flipped being in the middle) are also flipped. The game will get a bit frustrating if you flip at random, so be sure to plan your moves because there's a lot of levels to go through that are actually more difficult - but also more fun!
