Endless Tower Defense Games

How Endless Defense works

Endless Defense is rated medium and uses one long fixed path. The rules that make it different:

• Waves never stop. Enemy health scales up every wave.
• A boss every ten waves. Wave 10, 20, 30 and so on each bring a boss with a large health bar and phases at 66 % and 33 % health.
• Interest. At the end of each wave you earn 5 % interest on banked gold, capped at 50 per wave.
• Auto-start. An optional toggle starts each wave automatically, useful once your defense is stable.
• Saved records. Your best wave and best score are stored in your browser.

The six towers are Pulse, Rapid, Sniper, Mortar (splash), Cryo (slow) and Amplifier, a support tower that boosts the damage of towers inside its radius.

Thinking in long runs

Interest has a sweet spot

Because interest is 5 % capped at 50 per wave, banking more than 1,000 gold earns nothing extra. Holding around that amount between waves is free income; hoarding beyond it is gold that is not defending you. Early on, spending to stay safe is usually right. Once the defense is comfortable, keeping a reserve near 1,000 pays for your later upgrades. The tower defense economy guide goes into this trade-off.

Scale, do not just patch

In a fixed-length game you can finish with a defense that only just holds. In an endless game, health keeps rising, so the question each wave is whether your damage is growing faster than the enemy's health. Upgrading well-placed towers to level 3 is usually the most efficient way to keep up.

Amplifiers multiply everything around them

Because the Amplifier boosts every tower in its radius, the best place for one is the centre of a tight cluster of damage towers. Boosts from several Amplifiers do not stack, so a second Amplifier should cover a different cluster, not the same one.

Prepare for every tenth wave

Bosses resist half of any slow, so Cryo helps less against them than against normal waves. Use the build phase before each boss wave to add single-target damage, and consider setting a Sniper to Strongest targeting for the boss.

Use auto-start carefully

Auto-start saves time in the early waves. Turn it off before a boss wave or whenever you want time to rethink your layout. You can pause at any time with Space.

Other games with a similar feel

If you like surviving under pressure but want a game that ends, the survival defense collection includes Zombie Defense, Boss Defense and Jungle Defense alongside Endless Defense. For its setting and its Pulse, Sniper and Cryo style towers, Endless Defense also sits in the sci-fi tower defense collection with Space Defense and Robot Defense. More endless modes are planned, but we have no dates to share.

Who endless tower defense suits

Score chasers, players who like building an engine that keeps growing, and anyone who wants a game they can dip into again and again with a clear personal record to beat.
