Kingdom Rush is a tower defense game developed by Ironhide Games. The game has been widely praised for its strategic depth and replayability, and has won numerous awards, including Best iPad Strategy Game at the 2012 IGN Awards.

The game takes place in a world, which is constantly threatened by various monsters and enemy armies. Your task is to defend the kingdom by strategically placing defensive towers along established paths to prevent enemy units from reaching the end point. The total number of health points is 20, and every time an enemy invades, your health value will be reduced by one.
There will be a total of three slots in this game. In these three slots, you can choose the difficulty arbitrarily: casual, normal, veteran.
Every time you kill an enemy, you can get a different amount of gold coins. Gold coins can be used to upgrade the tower, but the gold coins cannot be accumulated to the next level, so the gold coins need to be used up in this level in time. Some gems can also be obtained in the game, and these gems can be used to buy magic potions in the store.
As the level of the game increases, more and more difficult enemies will appear. There are some information about new enemies will appear on the left side of the screen.

There are four types of towers in Kingdom Rush: Archer Towers, Footmen Barracks, Mage Towers, and Dwarven BomBard. Each tower has its unique strengths and weaknesses, so it‘s essential to understand them to use them effectively.
Archer Tower: It is your standard tower that fires arrows at enemies. They are relatively cheap and can be upgraded to deal more damage.
Footmen Barracks: These towers are used to train soldiers who will fight against enemies. They are more expensive than Archer Towers, but they are useful for slowing down enemies.
Mage Towers: They fire bolts of magic that deal damage over a wide area. They are particularly useful against groups of enemies.
Dwarven BomBard: It is slow but pack a powerful punch. They are great for taking down tough enemies or groups of enemies.
You must balance their resources and tower placements against different types of enemies and their respective strengths and weaknesses. As the game progresses, you can earn coins and experience points, which can be used to purchase new towers, upgrade existing towers, and unlock new abilities.

So how can you pass the game smoothly? Here are a few key points worth noting:
Planning Tower Placement - The key to success in Kingdom Rush is planning ahead. Think about the types of enemies that will come at you, and place your towers accordingly. For example, if you‘re facing heavily armored enemies, you‘ll want to place towers that deal a lot of damage. On the other hand, if you‘re facing highly mobile enemies, you‘ll want to use towers that slow them down.
Upgrade your towers - You can upgrade your towers to make them stronger. This is especially important as waves of enemies grow stronger and more numerous. Make sure to upgrade your most important towers first, and try to keep them on the same level.
Use your heroes wisely - you have a hero who can move around the map and fight enemies directly. Use your heroes strategically, as they can deal massive damage and have unique abilities. Don‘t be afraid to move them around the map to help defend different areas.
Utilize Special Abilities - You also gain special abilities that you can use to turn the tide of battle. These include calling in reinforcements, dropping bombs and summoning creatures to fight by your side. Use these abilities sparingly, as they usually have long cooldowns.
Keep an eye on your resources - you‘ll need to spend gold to place towers and use special abilities. Make sure you‘re not overspending and that you have enough gold to upgrade your towers when needed. You also need to watch your health value as losing too much can be game over.
