These are the biggest games on BoredKid.com: full 3D worlds that run right in your browser and that you can share with other players online. Build a village with a friend in Blockwild, or race strangers across a whole city of rooftops in Rooftop Rush. There is nothing to install and no account to make. Just open a game, pick a name, and you are in. Both games also work perfectly well on your own, so if nobody else is around or your connection drops, you simply keep playing solo.
Blockwild is a voxel sandbox where every hill, tree, beach and cave is made of blocks you can dig out or build with. Each world grows from a seed number, and that seed doubles as the join code: when a friend types the same seed on the New World screen, you both land in the same world and see each other walking around. Every block either of you breaks or places shows up for the other player straight away and is saved for your next visit, so a shared build keeps growing over many sessions. A day and night cycle, real shadows and lit torches make it worth building something you will want to look at after dark. Play Blockwild.
Rooftop Rush drops you onto the rooftops of a large 3D city and challenges you never to touch the street. Sprint, slide, vault low walls, run along billboards and climb fire escapes to cross the gaps between buildings. Everyone who is online shares the same city, so you will see other runners flipping across the skyline around you. When you want a goal, four time-trial courses, from a gentle rooftop sprint to a climb up the tallest towers, each keep a top-10 leaderboard of the fastest runs. Choose from three runners and switch between sunset, daytime and a neon night whenever you like. Play Rooftop Rush.
