Your major objective in this game is simple yet highly challenging: defeat the opponent in 1v1 battles using powerful cannons and protect your base from being destroyed. Aim for winning more and more trophies to improve your rank.
Spawn and merging cannons
Press “Buy Cannon” to spawn them on your base. Drag two identical cannons (cannons of the same level) together to upgrade them to a higher level, able to launch stronger units. Keep spawning and merging to reach higher tiers, but do not forget your ultimate mission: do not let the opponent approach and attack your own base.
Watch the opponent and adjust your strategy
There are different lanes in the arena. There are multiple lanes in the arena. Keep a close eye on each one, especially where and how your opponent places their units. Adjust the number of your own units strategically in every lane to counter their advances and prevent them from breaking through.
If you want to launch a strong offense and eliminate your opponent’s base quickly, concentrate a large number of units in the lane where they have the weakest defense. Overwhelming that lane forces them to scramble, giving you a direct path to victory in MergeDuel.io.
Win the competition and upgrade your units
You win the game when the enemy’s base is destroyed completely. This gets you coins and trophies. Spend those earned coins to upgrade your units' stats like damage, health, attack speed, and radius.
