In Bridge Legend Online, you will play a character trying to save his Princess. In the game, there are cliffs between you and your princess and you try to save her by building bridges over those cliffs. There are many chapters in the game but you have to start from Chapter 1. New chapters are unlocked as you complete missions with the materials given to you. The difficulty level increases as you pass the levels. You need to think strategically and in a planned way, using your intelligence and attention. If the bridge you built is wrong, your hero falls off the cliff and dies and you have to start from the beginning of the level.
