The 5 things to know before
starting a tower defense game
- Start with the tutorial:
every game on this list has a 20-60 minute tutorial. Skipping it means missing mechanics that take hours to learn later.
- **Build around 1-2
strategies**: every TD has dominant strategies (e.g., "Permaspike" in Bloons TD 6, "AOE arts damage" in Arknights). Generalist players plateau at mid-rank.
- **Don't spend money on
day 1**: gacha games are designed to make early spenders pay the most for the least value. Wait until you understand the meta.
- Use the wiki: every
TD has a community wiki with detailed strategy guides. The wiki is more useful than any built-in tutorial.
- Play the events: most
TDs have limited-time events that reward exclusive units. Missing events means missing the best rewards.
