Engineered Bases or as Supercell likes to call them Lopsided Bases continue to grow in popularity. Just keep reading if you want to know more about Engineered Bases.

An Engineered Base is a base specifically built for war, it is sometimes called a defenceless base. The base overwhelmingly promotes offences over defence. The objective of an Engineered Base is to provide a matchmaking advantage in war.

In war clans are matched on the overall strength of its members. Strength is based on each member’s attacking power (troops, army camp capacity, spells and heroes) and defensive strength (defence buildings, walls, traps and heroes).

Matchmaking will prioritise defensive capabilities in pairing Clans. Powerful, late-game defences and troops like Inferno Towers, Eagle Artillery and Grand Warden will have much greater matchmaking impact. A full guide to matchmaking can be found here.

As the Clash of Clans algorithm in matchmaking favours defence, many clans build their bases to exploit matchups in their favour, to do this they favour developing offensive troops and maintain a very low level of defence.

Examples of Engineered Bases


Creating your own Engineered Base

Engineered bases can look very similar to rushed bases. You are advised that an Engineered Base should not be you primary account. Many clans would refuse you clan entry as they appear rushed.

Building them is easy, upgrade your Town Hall to any level and ensure that the defences are 2 or 3 levels below. These bases should only be considered for those active in war as farming with these bases are troublesome due to their poor defence.
