The Best Roblox Tower Defense Games According to My 8-Year-Old

If there’s one thing my 8-year-old knows better than I do, it’s Roblox. Specifically, Roblox tower defense games. Whether he’s fending off waves of zombies or setting up futuristic defenses with cartoon characters, he’s got opinions—and lots of them—on which Roblox TD games are worth your time (and Robux).

So I sat down with my favorite tiny gamer to get the inside scoop. This list is all him—I’m just the parent typing it up and making sure you know how you can actually earn free Robux to play these games with help from Fetch.

How to earn free Roblox gift cards with Fetch Play

Before we dive into the list, let’s talk about how to unlock Robux (for free!) without asking your kiddo to do extra chores.

With the Fetch app, you can earn rewards for everyday things like snapping your grocery receipts—but it gets even better with Fetch Play. Fetch Play gives you bonus points for playing mobile games (yes, really). Those points can be redeemed for free Roblox gift cards, and the whole process is super easy.

Here’s how to do it step by step:

1. Download the Fetch app: If you don’t already have it, download Fetch from the App Store or Google Play.
2. Go to the “Play” tab: Tap the “Play” icon to explore available mobile games.
3. Choose a game and start playing: You’ll see a list of featured games that offer bonus points. Select a game, tap “Play Now,” and download it through the link provided.
   • Pro tip: You must download the game through Fetch for your progress to count!
4. Complete tasks to earn points: Each game has specific tasks—like reaching a certain level or playing for a number of minutes. As you complete those goals, Fetch rewards you with points.
5. Redeem your points for Roblox gift cards!

Once you’ve racked up enough points, tap on your point balance to go to the “Rewards” tab, search for “Roblox,” and redeem your points for a Roblox gift card. Boom—free Robux!

It’s seriously that easy. Your kid gets to play games, you earn rewards, and nobody has to open their wallet. Now that’s a parenting win.

What is a tower defense game?

For the grownups who might not be familiar: A tower defense game is all about strategy. You place different types of “towers” (which can be anything from cannons to superheroes) along a path, and those towers automatically attack waves of enemies trying to reach the end. The goal is to stop the bad guys before they get through.

Now in Roblox, tower defense gets way more creative. You’ll find everything from anime-style battles to zombie apocalypse vibes. It’s wild, it’s fun, and it’s highly addictive.

The 10 best tower defense games on Roblox (and which units to equip for each one)

Here are the games my son plays on repeat and insists are the absolute best tower defense games on Roblox, along with his review of each and his favorite units to equip if you want to win:

Why it’s so popular: Tons of maps, constant updates, and the thrill of teaming up with friends to take down bosses.

Why my 8-year-old loves it: “It’s just one of the OGs. You fight zombies, and I just think it’s really cool. Also, they have some fire emotes.”

His favorite units to equip: Scout, Sniper, Paintballer, Demoman, Soldier
