Dragon Tower Defence Guide: Build and Merge Defences in Tower Swap

Searching for dragon tower defence? The closest confirmed match in the supplied material is Tower Swap, a puzzle game that combines match-3 tile swapping with tower defence. Your objective is to stop dragons from reaching the castle by turning resources into defensive structures, then merging those structures into stronger units. The key challenge is deciding when to upgrade and when to keep several smaller defences covering the board.

How Dragon Tower Defence Gameplay Works

Each round gives you a limited number of swaps before the dragons attack. Use those swaps to arrange three matching resources. A group of three resources becomes a defensive structure, while three matching weapons or walls can be merged again for a more powerful unit.

Merging is not always automatically the best move. A larger defence may be stronger, but combining three units also reduces the number of positions covering the map. Before every attack, consider whether a merge improves your immediate protection or leaves another area exposed.

The source confirms that any tile can be swapped, even when the move does not create a match. This gives you flexibility to reposition resources, prepare a future combination, or improve the layout before the next dragon attack.

Resource and Defence Guide

The first four resources directly create combat or defensive structures. Gold works differently: its chest can provide additional swaps and may include items that immediately upgrade resources. Because swaps are limited, gold can be especially useful when you need to extend your preparation phase, although the available chest contents are not guaranteed.

Once a structure has been created, three matching weapons or walls can be combined to produce a stronger unit. Keep an eye on the board before merging, since removing three separate defences can reduce coverage even if the replacement is more powerful.

A Practical Preparation Routine

Use this sequence when preparing for a dragon attack:

1. Check your remaining swaps. You cannot make unlimited moves before the attack, so avoid spending swaps without a clear improvement.
2. Look for groups of three resources. Match stone, gunpowder, ice, logs, or gold to create the defence or chest associated with that resource.
3. Protect important areas. Place your structures so your castle has coverage rather than concentrating every unit in one location.
4. Delay unnecessary merges. Three matching weapons or walls can become a stronger unit, but merging removes three separate positions from the board.
5. Use special chest rewards carefully. Gold chests can contain swaps, TNT, or anvils, which may help you upgrade before the attack.
6. Reassess after every merge. A stronger unit does not always provide better overall coverage.

Boss Dragon Preparation

The first boss dragon levels identified in the source are day 10 and day 20. Before a boss round, the game indicates the area where the dragon will appear with an arrow. Use that warning to adjust your defences toward the expected attack area before your remaining swaps run out.

Defeating a boss does not necessarily end the danger immediately. The source states that a defeated boss releases a large number of smaller dragons, so your board should remain capable of handling follow-up pressure. Avoid using every available resource on one large merge if doing so leaves too little protection for the smaller dragons that follow.

Accounts, Clans, and Rewards

An account allows you to create a custom avatar, join a clan, compete with other players, earn gold, and unlock chests with rewards. The source also states that gold coins are awarded at the end of each game and can be used to buy lives or open chests early.

These account features are separate from the core match-and-merge loop. You can focus on building defences and surviving attacks first, then use earned gold and clan features as additional progression options.

FAQ

Is Dragon Tower Defence the official game name?

The supplied source identifies the game as Tower Swap. “Dragon tower defence” describes its dragon-focused tower-defence gameplay, but the material does not independently confirm it as the official title.

What should I merge first?

There is no single confirmed best merge. Merge when the stronger unit improves your protection, but delay the move if three separate weapons or walls provide better coverage for the upcoming attack.

When do boss dragons first appear?

The source identifies day 10 and day 20 as the first boss dragon levels. An arrow shows the area where the boss will appear before the round.

Can every tile be swapped?

The supplied controls section says that any tile can be swapped, even if the move does not make a match.
