People like age of war games because they are easy to learn and play. But they still have a lot of strategic depth and the chance to be used again. Because of this, tower defense games are some of the most addicting games that can be played on smartphones and tablets.

Tower defense games are fun and popular because their strategies are so flexible, easy to understand, and easy to change. Even if you aren't a pro, you can still come up with your own plan of attack.

Most tower defense games feel different because they use different systems and strategies.

In fact, there are a few things that all the best Tower Defense games have in common.

1. Give people time to make plans

It's best to give your players some time to rest between groups of threats. This gives them a break, and it also gives them a chance to change their strategy. What if I took these towers down and set up over there? Even if you have to make a few changes along the way, it's very satisfying to see a plan come together.

2. Give them a lot to choose from

People will play your game more than once if you give them more options. And the more people will stick around. It's also good to have a lot of different enemies, each with a different weakness. This keeps teams from using the same response over and over again. (Which can make the game get old fast.)

Changing how the enemies in each wave are chosen can also help. This means that the person can't make too much of a plan. And they may have to change their plan for the next wave totally.

3. Limit what they can do

When a player doesn't have enough coins to buy all of the weapons they want, they have to choose. Do I improve my attack towers or add a frost attack to make it hard for them to get through that corridor? Should I worry about the big bad guys or the small ones?

This also means that they can't use all the tools they have. Remember: you can't have a task without giving up something. What are they going to give up? And will that be too much to give up?

4. Leave room for imagination and combinations

One of the best parts of a good Tower Defense game is finding a way for two towers to work together that you didn't expect. Sure, you could put arrow traps all along the passageway. But what if these arrows could catch fire when they pass over a fire pit? Now, the person can be more careful about where they put their arrows to get a better result.

And the more your towers talk to each other, the more likely it is that your players will find answers you never thought of. At start, you don't need a lot of contact. Instead, you can add new towers slowly, month by month, and plan how they will work with your other buildings.
