About this game

MERGE, BUILD, AND DEFEND

Your fortress is under attack! Choose and place buildings, merge matching ones to make them stronger, and prepare for waves of monsters. Build structures that train knights, horsemen, archers, and mages, while all kinds of turrets and barricades attack or slow down enemies as they approach. Face skeletons, slimes, dragons, giants, and even stronger foes that appear as you progress. Adapt your setup to each threat and prepare for mighty bosses that can quickly break through a weak defense.

MAKE EVERY TILE COUNT

Space is limited, so plan your fortress carefully. Clear trees to open new tiles, decide where to place buildings that train different units, and find the best spots for barricades and turrets. Use every tile wisely, leave enough room to place and merge buildings, and create a layout that balances attack and defense.

LEAD HEROES INTO BATTLE

Place a hero on the battlefield to fight alongside your army. Each hero has unique stats, a combat skill, and a permanent boost. Upgrade your heroes, equip gear with useful bonuses, and prepare them for regular battles and special challenges.

EARN GOLD AND GROW STRONGER

Build gold mines to earn extra gold during each wave, but protect them from enemy attacks to collect the full reward. Spend your gold on rerolls to search for better buildings, gain experience by merging structures, and choose a new upgrade each time you level up. Strengthen your units, improve your defenses, or pick bonuses that fit your current strategy.

FEATURES:

• Units and Defenses - Build structures that produce different units or protect your fortress

• Strategic Placement - Clear trees, manage limited space, and balance offense with defense

• Merge and Upgrade - Combine matching buildings to create stronger structures

• Powerful Enemies - Face skeletons, slimes, dragons, giants, bosses, and unexpected threats

• Gold Management - Protect gold mines and spend your earnings on building rerolls

Lead your forces, prove your strategic skills, and build a kingdom no enemy can conquer!
