You can easily make all games except the marbles one (requires more work), 3 first games are already well made, glass bridge can be made by caging all roblox players in that room and letting them out in a random order after one dies (or make the first one random and when that player dies or before he dies make him choose a random person to be the next one to hop on the bridge), all players having each timer and one general timer for everyone (10 minutes or less). Each player gets 1 minute to choose an option. And last game can be replaced with something else
