Egglocke is a cool challenge in Pokemon games. You replace all Pokemon with eggs. These eggs come from a bunch of Pokemon chosen by you or someone else. You can only use the Pokemon that hatch from these eggs. You also have to follow Nuzlocke rules. Egglocke makes Pokemon games more surprising, harder, and fun. Some Egglocke ROM hacks are Pokemon Leaf Green, Pokemon Victory Fire, and Pokemon Emerald. To play these, you need an emulator and the right ROM files, which you can get from the links on the page.
