About Kingdom Tower Defense

Kingdom Tower Defense is a classic lane-defense strategy game. Enemies march along a winding dirt road toward your castle, and you spend coins to build towers on the grass beside it. Scouts are fast, grunts are sturdy, heavy tanks soak up lots of damage, and a boss appears every fifth wave.

Each tower type has a job. Archers fire quickly at single targets, cannons deal splash damage to groups, and frost towers slow everything they hit. Towers can be upgraded twice for more damage, range and fire rate, or sold for part of their cost if you want to rethink your layout.

How to Play

  1. Choose a tower type from the toolbar at the bottom of the board.
  2. Click or tap a grass tile beside the road to build it, if you have enough coins.
  3. Press the wave button when you are ready. Defeated enemies give you more coins.
  4. Select a built tower to upgrade or sell it. Enemies that reach the castle cost lives.

Game Objective

Survive all 20 waves without losing your 20 lives. Leftover lives and coins add to your final score.

Tips & Strategy

  • Corners are prime spots because towers there can hit enemies on two stretches of road.
  • Put a frost tower in front of your cannons so slowed enemies spend longer in the blast zone.
  • Upgrading a well-placed tower is often better value than building a new one in a weak spot.
  • Before a boss wave, keep some coins spare for emergency upgrades.
