Call your units and challenge other players in a race to conquer bases in MergeDuel.io! Can you overpower your opponents and emerge victorious in all your battles?
Your objective in this game is to defeat your opponents in each match by conquering their base. When you start, you will be matched with another player. The gameplay is simple. At the bottom of the screen, you will see the "add cannon" button. This will randomly place cannons on your grid. Your grid's space is 3x5, and only the cannons placed on the grey spots can be used. You can use the brown spots to store other cannons. If you merge the same cannon type of equal values, you will merge them into a more powerful one. The cannons come in 3 types: melee units, magical units, and ranged units. The higher the value of a cannon, the powerful the unit it spawns on the battlefield. Overpower the units of your opponent and destroy their base to win. You can use the coin rewards to upgrade your units! Enjoy!
