Build a Tower Defense Wiki

Best for: Learning path building and creating a functional first defense

Use alternating horizontal stretches connected by turns to create a longer route than a straight line.

Start with two or three major turns before attempting a more complex design.

Best for: Extending enemy travel distance within a limited area

Create repeated back-and-forth sections that make enemies cross the same defensive area several times.

Prioritize a usable tower position over adding one more short path segment.

Best for: Getting more attacks from towers near the middle of the route

Route monsters around a central building area so strong towers can cover multiple sections from one position.

Compare actual attack coverage before committing to the central arrangement.

Best for: Creating a long continuous route with many turning points

Guide monsters along the outer edge of your building area before turning inward through progressively smaller sections.

Plan the route's exit before constructing the final inner turns.

Best for: Increasing the time enemies remain under attack

Position towers where their attack ranges overlap the most important parts of your monster route.

Judge placement by actual target coverage rather than visual proximity alone.

Best for: Reducing the chance of survivors reaching your castle

Reserve defensive positions near the last path sections so surviving monsters stay exposed to additional attacks.

Treat the final approach as backup coverage rather than your only defense.

Best for: Finding weaknesses and improving an existing design

Use enemy movement and tower performance to decide whether your route needs more length, better turns, or improved coverage.

Change one major element at a time so you can tell whether the adjustment helps.
