Level 1-1

Level 1-1 is the first level in Plants vs. Zombies, Plants vs. Zombies: Journey to the West, and Plants vs. Zombies: Great Wall Edition, and it is the first Day level. When the level is finished for the first time, the player unlocks the Sunflower.

Difficulty

 * This level is self-explanatory. All you have to do is place Peashooters in two spots, and you automatically win. It does not matter which spot. If the Peashooters get eaten, the lawnmower will be used, killing all zombies.
 * The best way to win is by placing as much Peashooters as possible in the back rows.
 * When played the first time, it is impossible to lose this level.

Strategies
Place Peashooters wherever you want, and you will win, as it is almost impossible to lose. Though if you are looking for a more serious strategy, place Peashooters in the two left-most spaces (see below). This will ensure that they won't be eaten.

Trivia

 * The player can get the Sunny Days achievement here by not placing the second Peashooter and collecting 8000 sun.
 * It is unknown why the zombies do not travel on other rows.
 * It is also unknown why plants cannot be planted on the unsodded rows.
 * However, zombies can do this in Unsodded, a hidden mini-game.
 * If the player finishes through the Adventure Mode for the first time and restarts at this level, the level will contain a full lawn and two flags.
 * This also applies to Level 1-2 and Level 1-3.
 * It is possible to get the Last Mown Standing achievement in this level. Put two Peashooters in the last two square where the zombies are coming close and let one of the zombies eat it. Do not plant anymore Peashooters and wait for the zombies to get destroyed by the lawn mowers.
 * This achievement is only obtainable in the iOS and Android versions.
 * It is the only level with one row on the lawn.
 * It is the only level where the player starts out with 150 sun.
 * This is because it is a tutorial level.
 * Level 1-1 when played for the first time, Level 2-5, and Level 4-5, and Level 5-10 are the only Adventure Mode levels without the Flag Zombie..
