 A daptive D ifficulty

 Plants vs. Zombies 2 is using an A daptive D ifficulty system. This means that the more the player wins, the next level (or Day) will be more difficult. It seems that this A daptive D ifficulty mechanism will affect Piñata Party but not Endless Zone.

 If the player failed the object of a level (Day), such as let zombies reach the player’s home, unable to defend endangered plants, unable to kill specific amount of zombies in specific time, unable to produce at least a specific amount of sun or let the zombies trample the flowers etc… the player may try to Retry the level (Day). Then the d ifficulty of the same level (Day) may be lower. However, if the player chooses to Restart it, this will not count as a fail and the d ifficulty will not be affected.



 After the first fail, the game may show the player an advertisement for 30% off Gold purchase.

 If the player retries and continues to fail, after the 4 fails, the game will provide the player 1 free Power Up.

 If the player still retries and continues to fail, after 4 more fails (the 8 fails), the game will provide the player 3 free Power Up and the game should be at the easiest d ifficulty.

 At the easiest d ifficulty, there will be fewer zombies and in some levels (Days), more Plant Foods may be provided. The strategies or tips provided in this Wiki should work for level (Days) at easiest d ifficulty but may not work for hardest d ifficulty.



 Some level, such as Day 16 of Big Wave Beach, is still extremely hard even at the easiest d ifficulty due to the dependence of luck of what is spawned at the conveyor-belt.
