Tower placement basics that fix half your losses

When people ask why they keep losing in tower defence, the answer is almost always placement, not upgrades. A cheap tower in the right spot outperforms an expensive one in a bad one.

The single biggest tip: build near the longest stretch of path an enemy will walk. Corners and U-bends are gold because units spend more time in range. Dropping a tower at a corner effectively doubles its firepower.

Layer your damage types. Slow enemies down first with frost or gravity effects, then let your high-damage towers do work while the wave is bunched up. This combo wins more maps than any single upgrade.

Finally, keep a small reserve of currency during boss waves. Being able to slap down one emergency tower at the right moment has saved me more runs than I can count.
