Gameplay
Fortress Merge gameplay: merge buildings and defend the castle
Game overview
Merge, build, and defend
Fortress Merge is a free-to-play merge tower defense from TapNation and Tartatin, published by QubicGames. You drag buildings onto a tight grid, merge matching tiers, and hold waves of skeletons, slimes, dragons, and giants before they crush the castle. The Steam, Xbox, and PlayStation versions launched on 4 September 2026 after a long mobile run. Start with the beginner guide, learn when to merge, then lock a front-to-back layout. Spend gold using the economy guide, check the building tier list, and pick a hero plus gear plan. Daily gem routes live on free rewards. Challenge modes and the console launch are covered in updates.

Quick start
Five steps that turn a messy board into a fortress that lasts.
- 1
Learn the board before you merge
Clear trees, place walls on the lane, and keep the castle alive. The getting started guide covers shop, Fight, and the first ten waves.
- 2
Merge walls and mines, not every camp
Two matching buildings make a higher tier, but extra barracks often beat one big camp. Read when to merge before you collapse your army.
- 3
Spend gold on space, then rerolls
Rerolls get expensive. Unlock tiles first, protect mines, and follow the gold and upgrades order so wave 10 still has damage.
- 4
Pick a hero and stop scattering blueprints
Each hero brings a skill and a permanent boost. The heroes hub and gear guide explain who to invest in on mobile versus the three-hero Steam build.
- 5
Prep the boss wave on purpose
Sell leftover mines, fill gaps with walls, and take global cooldown or HP skills. The boss guide is the checklist for wave 10 and the 13-wave maps.
