GLOWZ

GLOWZ is a collaborative browser game played in one shared world. Everyone who is online digs through the same map at the same time. Tap the sky to drop a ball, watch it smash into blocks, and follow the path it opens as you break terrain and dig tunnels with other players. The holes you make stay in the shared world, so each session builds on what everyone else has done. It runs right in your browser, with no download needed, and you can join the digging from the moment the page opens.
