What Makes Tower Defense in Pet Simulator 99 So Addictive
The Tower Defense mode of Pet Simulator 99, introduced on June 14, 2025, has players position towers (or units) along walkways in defense of invading waves of breakables that are swarming to break into your castle gate.
Your towers make automatic attacks with every incoming wave, breaking objects to get Coins. With these Coins, it is possible to reinforce Towers in the middle of the match or invest in the ones that are better using the event currency, Rubies.
Building and Upgrading Your Forces
Random Unit Eggs can be hatched using Rubies to get Towers, or a predetermined one may be purchased at the Unit Merchant, which has the advantage of a guaranteed unit, but at a higher price. All the towers possess four important characteristics: damage, DPS, speed, and range.
These you can improve during the game with Coins on the spot and off the game by leveling up and fusing doubles to permanently increase stats. The ability to merge or fuse units enables you to group your power into fewer and more powerful towers.
How Maps, Stages & Modes Interconnect
Tower Defense offers 8 different maps, which last of six main stages, which constitute 48 core stages, and that does not even account for other difficulty settings. As you advance, though, you unlock tower slots: 4th slot when clearing Map2, 5th slot when clearing Map3, 6th slot when clearing Map5. After clearing Stage 6 of any map, players have a chance to enter the difficult Infinity Mode, and they are promised Titanic rewards and Huge-Level pets when they reach the end of endless waves.
Mastering Tower Combos and Placement
The best tower defense combination is a combination of covering and firepower early on. To begin with, install smaller towers such as the Safari Monkey or Ninja Dalmatian around the spawn points so that they occupy time and whittle down waves. When the stronger waves unexpectedly happen, save some Coins during the match to make emergency positions. When a tower levels up in the game, prioritize buffing the damage and long-range to maximize the cost of upgrading towers.
At the periphery of the match, notice the blending of the cloned towers to the outside edge. To apply permanent XP boosts on important units, you should use XP Tokens (I, II, III), which you gain when opening Gift Bags specifically during Infinity Mode. The fastest-firing towers should be mixed with slower, stronger towers to help you overcome the flaws in your build to maintain the synergy.
AFK Mode: Waiting, but Rewarding
The AFK Mode presents a great means of practicing passive farming. You are awarded a big stockpile of Coins to put and upgrade towers, and then fall into idleness. After the return will be automatic, i.e., earning of Rubies, Coins, and conceivably new tower units, depending on how many waves you fenced off. It is most suitable during the preparation of your team and in the accumulation of money during non-play times.
Chasing the Biggest Rewards and Pets
It is in the Infinity Mode that the winnings of high-stakes become a brilliant phenomenon. The drops become (at least) exponentially more challenging to execute as the waves do, and the best of them–the Titanic Nuclear Dominus, Huge Ninja Dalmatian, and the rest–are very good challenges.
Each standard stage round provides a possibility to win a Huge Safari Monkey, and Infinity Gift Bags offer an opportunity to win such a rare unit as the Huge Arcade Angelus. Also, the hardcore mode cranks the drop rates up to the max in all stages, with a more predictable way to your objects of desire.
Ruby and Unite Farming Strategy
Maximize Rubies by switching between Normal and Hardcore runs of easy stages to get guaranteed returns. That is why I would just save up those Rubies to hatch Unit Eggs or to buy wanted towers directly. Employ the use of AFK runs daily to complement these earnings without any active participation.
To develop the account in the long term, buy leveling and freezing a skeleton of towers to get a stronger start in each game. When opening up further slots, open up your setups to develop multi-layered defending its structures with distinct purposes for each tower.

Final Thoughts
Pet Simulator 99 Tower Defense is a game of ideal strategy, upgrades, and a prize-to-hunt combination. Begin by clearing early projectiles to get access to all slots, complete a balanced tower by merging and promoting troops, and interchange normal, hardcore, Infinity, and AFK runs to maximize rewards.
When harvesting important resources, turn on the active Play option, and, when it comes to insignificant ones, leave the AFK Mode to fulfill its passive duty. With time, you will develop the most powerful network of defense to withstand the most severe Infinity waves-this will get you the most profitable pets and rewards the game has to offer.
