Find useful build spots
Look for bends and overlapping stretches where a tower can attack Bloons for longer. Leave space for a mix of defenses rather than spending all your cash at the first opportunity.

GAME OVERVIEW
Build a defense along the track.
Bloons Tower Defense 4 is a classic route-based tower defense game from Ninja Kiwi. Bloons travel along a marked path, and the player places monkey towers and other defenses beside it to pop them before they reach the exit. Each tower has its own attack style, so the best setup depends on the track, the available build spots, and the wave coming next.
Between waves, use earned cash to add towers or buy upgrades. Some defenses are better at covering bends and long stretches, while others are useful when Bloons bunch together or tougher types arrive. A balanced layout is usually more dependable than filling every open space with the same tower.
The game includes multiple tracks and tower choices, with challenge modes adding another way to test a defense. This embedded build is a single-player browser version, so the focus is on planning a map and seeing how long your setup can hold.
GAME ART
Tracks, towers, and incoming Bloons.
HOW TO PLAY
Place, upgrade, and defend.
Match towers to the wave
Select a tower from the game menu and place it in an available location beside the path. Different tower types attack in different ways, so combine them as new Bloons appear.
Upgrade with a plan
Select a placed tower to view its upgrades. Spend cash where it will improve coverage or damage most, then start the next round when you are ready.
Controls
- Mouse: choose a tower, place it on an open build spot, select a tower to manage upgrades, and use the round controls.
- Read the in-game tooltip and menu text before confirming a tower or upgrade.
- The game is presented in a 4:3 play area; fullscreen can make the classic interface easier to see.
Begin with a simple combination, then review which Bloons get furthest along the track. Use that as a clue for your next tower or upgrade.
