Merge Blast is a fantastic fighting game in which you must defend your castle with a cannon against enemy attacks.
Defend your fortress and upgrade your cannon to deal with the harsh environment's more challenging conditions. Stones of a specific value will rain down on your castle from above in an effort to breach the castle's defenses and conquer it. Obviously, you wish to prevent this, so you utilize a basic cannon. It requires you to shoot at the stones and hit them the indicated number of times.
To fire, depress the left mouse button and move the mouse back and forth. Clean your mobile device with your finger. Use the edge to shoot over the rail and protect yourself from the enemy's stone barrage.
