Merge and create the tallest fighters win fights and invade the enemy camp!
Drag numbered blocks to merge and upgrade their level. Then push the stack into the gates to create and deploy a tall fighter will charge the enemy camp. Your main goal is to breach the enemy border and invade his camp!
However, if one of your tall fighters is intercepted by an enemy's fighter, they will face off to see who is the tallest (and mightiest). Whoever wins continues charging down to invade the enemy.
Strategize your merges to create the best tall fighters to defend your camp and invade the enemy. Beware of hazards along the way that may weaken your fighters.
