Travel Log

The Travel Log is a feature introduced in the 3.5.1 update of Plants vs. Zombies 2. It tasks players with completing quests such as unlocking a certain plant or world. The player is then rewarded with coins and gems for completing these tasks. It also uses a ranking system to give the player a rank, which is then scored in Game Center or Google Play under the name of "Travel Log's Plank Ranks". These ranks can be leveled up by completing the quests for points. If the player has already completed quests before updating to 3.5.1, they will automatically be given the points and rewards they would've been given when they open the Travel Log menu for the first time.
