Merge Defense: Tower Merge TD

Little towers. Big decisions. Defend 30 waves across six realms, forge without a charge limit, and unleash crowned towers. Offline. No ads or in-app purchases.

Little towers. Big decisions.

Merge matching towers, build your frontline, and defend your castle through 30 waves across six distinct realms. Every new tower is a choice: combine it for power, or keep it to cover another stretch of the road?

MERGE, THEN MAKE YOUR NEXT MOVE Combine towers of the same type and level. Use the Forge to combine different tower types at the same level, keeping the type you choose first. Forging has no charge limit; you still need a compatible pair below the maximum level.

19 POSITIONS. ONE DEFENSE. Build across 15 formation spaces and four frontline positions. Balance Arrow, Cannon, Frost and Lightning as you unlock them. Keep enough anti-air firepower, slow dangerous enemies, and reposition between waves.

SIX REALMS TO DISCOVER Travel from Bellwind Meadow and Bloomvale to Amberwood, Moontide Coast, Skyglass Sanctum and Duskstar Citadel. A new setting awaits every five waves. Browse the Journey Atlas for a preview and tactical tips.

SMALL TOWERS, CROWNED FIREPOWER Grow towers through eight levels. Maximum-level arrows, cannonballs, frost and lightning each have their own attack effects. Choose upgrades and build combinations that suit your defense.

LEARN BY DOING An interactive practice course walks you through buying, merging, forging, deployment and other controls. Later campaign waves ask more of your formation, with between-wave refitting and chapter retries to help you adapt.
