If you’ve played tower defense games before, you’ll understand the basics quickly. If not, don’t worry—this guide will help you learn everything step-by-step.

In this article, you’ll discover how to place Towers, clear waves, earn rewards, unlock new maps, get powerful pets, and use different strategies to succeed in Tower Defense mode. Let’s begin!

What is Tower Defense Mode?

Tower Defense mode in Pet Simulator 99 is a strategy-based event. The goal is simple: stop enemies from reaching your base (the castle gate). You place Towers on the path and upgrade them to destroy enemy objects. As you progress, you earn rewards like Rubies, Coins, Pets, and special Towers.

This mode offers a mix of casual fun and tactical thinking. Whether you’re a new player or a returning one, Tower Defense mode is worth trying out.

Basic Gameplay Overview

When you enter a Tower Defense match, you start with a few Coins. You use these Coins to place Towers along the path where enemies appear. The enemies come out of a portal and move toward your base.

Your Towers automatically attack them. When enemies are defeated, they drop more Coins. You can use these to upgrade your Towers during the match.

Every stage has a fixed number of waves. You must survive all waves to win. At the end of a stage, you get Rubies, Pets, Boosts, and more.

There are 8 maps, and each map contains 6 stages. That means there are 48 standard stages in total. On top of that, there are Hardcore versions of each stage and Infinity mode for endless waves.

Game Modes Explained

Here are the different modes you can play in Tower Defense:

1. Normal Mode

• Basic version of the map.
• Easier enemies.
• Great for beginners.
• Rewards: Rubies, basic Pets, and Coins.

2. Hardcore Mode

• Harder enemies with more health.
• Enemies move faster.
• Better rewards (higher Rubies and chances for Huge Pets).

3. Infinity Mode

• Unlocked after completing Stage 6 of any map.
• Endless waves until your base is destroyed.
• The longer you survive, the more Rubies and rare Pets you earn.

4. AFK Mode

• You get 1 million Coins to place Towers.
• Once placed, the game continues automatically.
• You can leave your device and still earn resources.

What Are Towers?

Towers are the main units you place on the battlefield. These are different from the usual Pets in Pet Simulator 99.

You can get Towers from:

• Hatching Unit Eggs
• Buying from the Unit Merchant (using Rubies)

Tower Rarity and Stats

Towers come in different rarities—Common, Rare, Epic, Legendary, and more. The rarer the Tower, the better its base stats.

Each Tower has four important stats:

• Damage – How much damage it deals per hit.
• DPS (Damage Per Second) – Overall performance in combat.
• Speed – How fast it attacks.
• Range (RNG) – How far it can attack.

You can upgrade Towers mid-battle using Coins or level them up permanently using XP and unit fusion.

Starting Units

At the beginning, you’ll have access to simple Towers like:

• Safari Monkey
• Ninja Dalmatian

As you unlock new Units, you’ll gain access to stronger ones for tougher maps.

How to Get Towers and Pets

There are two main ways to get Towers:

1. Unit Egg Hatching

You can hatch Unit Eggs using Rubies. This is a random method, so luck plays a role.

2. Unit Merchant

You can buy specific Towers directly using Rubies. This costs more, but it’s guaranteed.

Pets and Their Locations

Some of the Pets you can earn in Tower Defense mode include:

Pet Name	How to Get
Huge Safari Monkey	Random drop in all rounds
Huge Ninja Dalmatian	Infinity mode
Huge Jetpack Cat	AFK Mode
Titanic Nuclear Dominus	Infinity mode
Huge Arcade Angelus	Gift Bag
Huge Zeus Bear	Dark Unit Egg
Titanic Mechanical Griffin	Dark Unit Egg
Huge Nightmare Cyclops	Clan battle
Others	From Magma Unit Egg

Tip: Complete all stages at least once to increase your chance of unlocking these Pets.

Tips to Win Battles

Here are some useful strategies to help you survive and win more waves:

1. Place Towers Early
   • Always place Towers at the beginning of the path to get more hits in.
2. Upgrade Wisely
   • Don’t upgrade all Towers at once. Focus on high-DPS Towers first.
3. Mix Tower Types
   • Combine fast-shooting units with high-damage ones for better control.
4. Keep Coins for Emergencies
   • Save some Coins in case you need to place emergency Towers during later waves.
5. Use Rubies Efficiently
   • Don’t waste Rubies early. Save them to buy rare Units from the Merchant.

Unlocking Extra Slots

At the start, you can place only 3 Towers on the field. As you progress, you’ll unlock more:

• Slot 4: Unlocked after clearing Map 2
• Slot 5: Unlocked after Map 3
• Slot 6: Unlocked after Map 5

More slots mean you can build better battle plans with stronger combos.

Leveling System vs. Battle Upgrades

You can upgrade Towers in two ways:

1. Battle Upgrade (Temporary)

• Use Coins during a match.
• Improves attack speed, damage, and range.

2. Permanent Leveling (XP + Fusion)

• Fuse other Towers or use XP boosts.
• Raises base stats for future battles.
• Best used on rare or powerful Towers.

Daily Grind Tips

Want to earn more without grinding every second?

• Play AFK Mode daily to farm Coins and Rubies.
• Repeat easier stages quickly for steady Ruby farming.
• Don’t forget to claim Gift Bags and check Merchant stock regularly.
