Before there were hundreds of towers, Monkey Knowledge trees, and complex upgrade paths, there was simply a dart, a monkey, and a wave of colorful balloons. Bloons Tower Defense (Bloons TD 1), released in 2007 by Ninja Kiwi, began as a humble Flash game — but it laid the foundation for one of the most iconic and addictive strategy franchises ever created.

Now, thanks to Lemon Web Games, you can play Bloons Tower Defense (Bloons TD 1) online directly in your browser, complete with mobile support and controller compatibility. This is where it all began — the original test of popping precision and tactical patience.

A Simple Idea That Changed Web Gaming

The concept couldn't be more straightforward: prevent bloons (balloons) from escaping the map by strategically placing monkey towers armed with darts and other popping tools. Yet beneath its simplicity lay a surprising depth that kept players coming back for "just one more round."

Each wave of bloons brought new challenges — faster movement, thicker layers, and trickier paths. With limited cash between rounds, players had to make smart choices about where and when to place towers. The right placement could mean victory; the wrong move could end your defense in seconds.

For its time, it was pure genius — quick to play, endlessly replayable, and easy to learn but hard to master.

The Birth of the Monkey Army

Bloons Tower Defense 1 introduced the world to what would become Ninja Kiwi's signature: a cast of quirky yet capable monkeys, each with their own attack style.

The first game's arsenal was small but mighty:

This limited lineup encouraged experimentation, and players quickly learned to combine tower types for maximum effect.

The Flash Game Era

Back in the mid-2000s, browser-based Flash games ruled the internet. Sites like Armor Games, Miniclip, and Kongregate were playgrounds for millions of players looking for quick, free entertainment — and Bloons Tower Defense became one of their biggest hits.

It had everything that made Flash games irresistible:

It wasn't uncommon for players to lose hours chasing the perfect strategy to make it just one round further. And while the graphics were minimal and the sound effects simple, the game's design shone through — a testament to Ninja Kiwi's sharp understanding of what made games fun.

The Start of a Legacy

Nobody could have predicted how far the series would go. What began as a single Flash title would evolve into Bloons TD 2, 3, 4, and eventually Bloons TD 6, introducing complex upgrade paths, hero units, and global leaderboards.

Yet, the charm of Bloons TD 1 endures. It's the purest form of tower defense — stripped of extras, focused entirely on timing, placement, and efficiency. Every balloon popped still feels satisfying, and every wave cleared remains rewarding.
