Basics / Six steps
Your first few waves, sorted.
Observe first. One well-chosen change teaches you more than rebuilding the whole defense.
Know the goal and the route
Before placing anything, find out what you’re protecting and what counts as a loss. Walk the route from entrance to finish and look for bends, junctions and stretches where one tower can cover a lot of path. Some games pick positions for you; others give you freedom. Read the tutorial before assuming you can move a tower later.
Learn what each tower does
Read a tower’s description and check its range indicator. Damage is only one factor: a tower might hit several enemies, slow them down, or suit a certain target. Learn a small set first, and check the targeting rules if the game explains them. A tower that can’t reach or affect an enemy can’t solve that problem.
Balance new towers and upgrades
A new position extends coverage; an upgrade strengthens one you already have. Pause when the game lets you and ask where the defense really struggles. Are enemies escaping an uncovered stretch, or surviving a well-covered one? Let that answer drive your next purchase. No single spending order works in every game.
Watch the enemies
Notice what gets through, then read any enemy information on offer. Speed, protection and movement type change which tools help. A bigger crowd isn’t the only threat. If one enemy type keeps surviving, check whether your current towers can handle it.
Change one thing at a time
After a failed attempt, keep one useful observation, such as a tower that sat idle for too long. Adjust its position or your upgrade timing on the next try instead of changing everything. Two similar attempts are easier to compare. In competitive play, remember another player’s choices can change the result too.
Check every purchase prompt
Free to install and free to use fully are different things. Read the amount, currency and item description before confirming. Check whether an offer is one-time or recurring. If you don’t want to spend, dismiss the prompt and look for free options. Device-level purchase authentication helps prevent accidental confirmations.
