Giants have a lot of health but are slow and have low attack power, so use them in groups.
Giants are weak against many defenses grouped together.
You can use Giants as a cheap meat shield while deploying other, higher damaging troops to destroy buildings.
Another strategy is to send many Giants with one or more Healers. Be wary of Air Defenses and other anti-air towers, however, as Healers are very weak and have many vulnerabilities.
In general, Giants make better distracting troops than Barbarians due to their much higher health. Because of this they are less vulnerable to Mortar fire and other splash damage, and are much harder to kill.
Giants can be especially susceptible to Spring Traps due to the predictable nature of their AI. Use this to your advantage and place strategic gaps in your Walls with defensive structures behind them, and fill the gaps with one or more Spring Traps.
Giants are reasonably good defensive Clan CastleTroops, as their high health means that multiple offensive units will have to be dispatched to deal with them (a Lightning Spell will not be sufficient). They will also take a relatively long time to kill, delaying the enemy attack. However, the problem with using giants as Clan CastleTroops is that when they come out to defend, they take up five spaces. This means that if the enemy has enough troops to one hit a giant, it will be more efficient to use five Barbarians, as the enemy troops will promptly have to reload. As such, it will take five times as long.
The Giant undergoes significant changes at level 6.
A level 1 and 2, the Giant wears a brown tunic with a red belt and copper buckle around his waist. He otherwise has no accessories.
At level 3, the Giant gains iron cuffs around his arms and iron knuckles on his hands.
At level 5, the Giant exchanges the dark metal cuffs and knuckles for golden ones.
At level 6, the Giant upgrades his cuffs and knuckles to a black metal. He also grows a long, thick red beard and dons a black feather cape.
At level 7, the Giant acquires a golden chestplate underneath its brown tunic that reaches to its shoulders.
When you tap the Army Camp the Giants all pump their fists in and out from their chests a few times, similar to humans cracking their knuckles.
In game if you closely look at the Giants when they're pumping their fists you can see that they have no eyes.
You can have a maximum of 48 Giants at one time in a complete set of fully upgraded Army Camps. This number increases to 55 if you include the 7 that can fit into a fully upgraded Clan Castle.
The Giant's low damage is visually seen by the attacks with their bare fists.
Of all Elixir troops the Giant has the lowest damage per housing space, tied with the Dragon (10 DPS per housing space at level 7).
The Giant's main Barracks image changed substantially as part of the "Witch" update (29 July 2013). However, this change did not affect the look of the in-game unit; when viewed in Army Camps or in battle, the Giant still has the same look as it did prior to the update.
When the Giant attacks a building, a puff of smoke rises from the target.
