Mini-games are features available in most versions of Plants vs. Zombies, where they are accessed through the main menu below Adventure Mode, or on the iOS, Android, PS3, Ps Vita, and Xbox 360 versions are accessed through The More Ways To Play menu. Mini-games variously have the player choose plants, use a conveyor belt to provide plants, or force the player to use set plants. There are twenty mini-games in most versions with various unique twists, such as smaller zombies or zombies with plants for heads. On the iPad, iPod Touch, iPhone, and Game of the Year versions, beating all the mini-games present will earn the player the achievement Beyond the Grave. However, the player must buy them in some versions. Many mini-games are closely related to PopCap's other games.
Mini-games can be found for the first time in a present dropped by a zombie in Level 3-2 of Adventure Mode. The mini-games given are ZomBotany, Wall-nut Bowling, and Slot Machine. The player can unlock more mini-games after the completion of Adventure Mode.
At first, mini-games cannot be accessed, but the mode is unlocked as the player progresses through the game. There will be three unlocked Mini-games before finishing Adventure Mode: ZomBotany, Wall-nut Bowling, and Slot Machine. After the player completes Adventure Mode, more mini-games will be unlocked, and the player must complete them to unlock further mini-games. Each mini-game yields one diamond after the first completion, and a bag with five gold coins in subsequent plays.
The player must complete all 20 Mini-games, the first ten Survival Mode stages, and the first nine Vasebreaker and I, Zombie Puzzle Mode games in order to get the Gold Sunflower Trophy. This will also unlock the Nobel Peas Prize achievement in the Plants vs. Zombies: Game of the Year Version.
On the iPhone, iPod Touch, and the iPad, some of the mini-games must be purchased from Crazy Dave's Twiddydinkies.
In the iPad version Vasebreaker is listed under Mini-games in addition to under Puzzle Mode.
Some mini-games are just harder versions of the levels played in Adventure Mode, which are Wall-nut Bowling (Level 1-5), Whack a Zombie (Level 2-5), Big Trouble Little Zombie (Level 3-5), Bungee Blitz (Level 5-5), and Dr. Zomboss's Revenge (Level 5-10).
List of Mini-games
- ZomBotany: Here, everything is normal, except that the zombies have plants instead of their usual heads. Whatever plant happens to be there, the zombie will act both like the plant and a normal zombie. For example, a zombie with a Peashooter on its head will walk towards the player's plants, shooting peas on that lane as it goes and eating the plants once it reaches them. Wall-nut Zombies have the same health as a Wall-nut. This Mini-game has a sequel.
- Wall-nut Bowling: Just like the one in Adventure Mode, the player must bowl Wall-nuts and Explode-o-nuts at the approaching zombies in order to kill them. Ricochets can earn the player money. This Mini-game has a sequel.
- Slot Machine: The player must pay 25 sun to pull the lever in order to get plants, more sun or more money. In order to complete this Mini-game, the player must acquire 2000 sun.
- It's Raining Seeds: Seed packets fall from the sky in this mini-game. The seeds will disappear if the player doesn't plant them shortly after they fall. It takes place on a fog level, and is not present in the PlayStation 3, Xbox 360 PlayStation Vita, and Xbox Live Arcade versions.
- Beghouled: It is just like PopCap's previous game Bejeweled, except the player's jewels will be plants which will attack the approaching zombies. Sun is obtained from successful matches and can be used to fill in empty spots (200 sun) or purchase upgrades. The level ends after 75 matches are made. This Mini-game has a sequel.
- Invisi-ghoul: A night-time pool conveyor-belt level with no fog, the twist is that all approaching zombies will be invisible. Plants will still fire at them, though, and the player can see the impacts and parts falling off the zombies. The player can use an Ice-shroom to see their places on the lawn. On the Xbox 360 version, the player can see which lane a zombie comes from.
- Seeing Stars: A front yard Daytime level in which the player must plant Starfruit on several outlined spots in the shape of a star, while also defending himself or herself. The player cannot plant anything except Starfruit (and Pumpkin) on the outlined spots, and he or she wins when each outlined spot has a Starfruit on it.
- Zombiquarium: Similar to Insaniquarium, in that the player needs to feed Snorkel Zombies brains to accumulate 1000 sun to purchase a trophy. If they are not fed, they starve to death.
- Beghouled Twist: Like Bejeweled Twist, in the same style as Beghouled, except matches are made through rotating plants in a clockwise direction.
- Big Trouble Little Zombie: All zombies are smaller, move faster and come in much greater numbers, but they are easier to kill. This Mini-game is not present in the DS and DSiWare versions. Instead, it is replaced with the Mini-game Heat Wave.
- Portal Combat: There are two pairs of portals around the map: when a zombie or projectile from a plant enters one of these, it exits through the other portal, in the same direction that it entered. Portals will randomly change places throughout the level.
- Column Like You See 'Em: Each plant that the player plants on the roof will be duplicated on each lane in that column, and zombies will come in much greater numbers, which causes lag.
- Bobsled Bonanza: A daytime pool level which starts with ice on all four ground lanes, several Zombie Bobsled Teams and Zombonis will appear throughout the level unless the player melts the ice. If the player does, he or she will face several Zombonis first.
- Zombie Nimble Zombie Quick: A normal daytime pool level, except everything will be much faster. This mini-game does not appear in the DS and DSiWare versions.
- Whack a Zombie: Zombies will appear from Graves, and the player must whack them with his or her Mallet. They will sometimes drop Sun, which he or she can use to plant Grave Busters, Potato Mines and Ice-shrooms. Ice-shrooms are replaced with Cherry Bombs in the iPhone and iPod Touch version. This level is similar to level 2-5 in Adventure Mode.
- Last Stand: A daytime pool level. The player starts with 5000 Sun and must survive for five flags. The player cannot plant free plants (Puff-shrooms and Sea-shrooms), and Sun Producing Plants (Sun-shrooms, Sunflowers and Twin Sunflowers) or the Imitater versions of them. It is one of most popular Mini-games. The player must plan a strategy before starting.
- ZomBotany 2: Like ZomBotany, though this one takes place in the Pool, and there are more types of plant-zombies, such as Jalapeno, Squash, Gatling Pea, and Tall-nut.
- Wall-nut Bowling 2: The sequel to Wall-nut Bowling, but with Screen Door Zombies, Dancing Zombies, Backup Dancers, and Giant Wall-nuts, which squash all the zombies in a row.
- Pogo Party: The player will face mostly Pogo Zombies in this Roof level, as well as normal zombies in the huge waves.
- Dr. Zomboss's Revenge: Just like the final boss, except this time Dr. Zomboss will have twice as much health and will send his minions more often.
- Buttered Popcorn: The player touches up to eleven zombies' heads at once to place butter there, then destroy them using the provided Cob Cannons. It is exclusive to the iPad and Android versions.
- Heavy Weapon: The player controls a Lawn Mower on the bottom of the screen with one joystick, while using the other to aim and fire Peas from a cannon on the lawn mower. It is exclusive to the Xbox Live Arcade, Xbox 360, PlayStation 3, and PlayStation Vita versions. This is similar to PopCap's game Heavy Weapon.
- Heat Wave: A Mini-game exclusive to the Nintendo DS and DSiWare versions of the game. It takes place in the Pool, in which only ten plants are given that can be moved anywhere that is needed. Sometimes the Peashooters tire from the heat, and the player then yells into the DS's built in microphone to encourage them, thus turning them orange and greatly increasing their firing speed for a short time. This Mini-game replaces Big Trouble Little Zombie.
- BOMB All Together!: A Mini-game exclusive to the Nintendo DS version of the game, in which the player is given 25 Exploding Plants to dispatch zombies with.
- Homerun Derby: A Mini-game exclusive to the Nintendo DS version of the game. A player must hit 30 Home Runs by using the stylus as a baseball bat while preventing the zombies from entering the player's house. And one of the mini-games that does not have to focus on Planting.
- Air Raid: A Mini-game exclusive to the DS version of the game, where the player controls a flying Gatling Pea with the stylus trying to defeat Dr. Zomboss in his flying Zombot. It has the same name as a Cancelled Mini-game.
- Zombie Trap: A Mini-game exclusive to the Nintendo DSiWare version, where the player attracts zombies using brains to trap and kill them.

- Sunny Day: Big Sun falls from the sky, worth 50 sun.
