Strategy and Defense Games
Strategy and defense games give you limited resources and waves of enemies, and ask you to make the numbers work. Merge two units into a stronger one, decide which slot guards the base, and upgrade at the right moment. Winning comes from good decisions, not fast fingers.

Most games in this category combine two ideas. The first is tower defense: enemies arrive in waves along a path and you position defenders to stop them before they reach your base. The second is merging: two identical units combine into one stronger unit, so you are constantly choosing between more defenders and better ones.
Siege Break and Avenger Guard lean on hero placement around a fortress. Plant Merge: Zombie War and Dark Myth: Monkey Merge are built around merging an army up through the ranks. Pinball vs Zombie adds a pinball table to the mix, with balls bouncing off your plants to trigger their attacks.
Simple rules that win defense games
One strong unit usually beats two weak ones, so merge whenever you have a pair - except in the last seconds before a wave, when an empty slot can be worse than a weak defender.
Put your strongest units where enemies spend the most time, typically near a bend in the path or right in front of the base. And when a wave ends, spend what you earned before starting the next one. Unspent gold defends nothing.
