Domino Stack Sort is a satisfying and strategic puzzle game that challenges your logic and planning skills. Your goal is simple but addictive: merge matching domino tiles in the same slot to reach the required level and complete the goal. But as the board fills up and new pieces keep coming, every move matters!

Use both lane-to-slot and slot-to-slot transfers to keep the board organized. Plan ahead to avoid getting stuck, because if you can’t fulfill the level’s merge requirement, it’s game over.

Throughout the levels, you’ll encounter two special mechanics that keep the gameplay fresh and challenging:
• Hidden Pieces: These are unknown tiles that remain a mystery until unlocked. You won’t know their color or type beforehand, adding a strategic twist to every decision.
• Ice Pieces: These tiles are frozen and can’t be moved or merged until you complete a specific number of merges. Once unlocked, they become active and can help you reach your goals.

Each level tests your ability to organize, predict, and execute merges efficiently. Stack up to 10 matching domino tiles in a single slot to evolve them into the next type. Chain reactions, smart stacking, and timing are the keys to victory.

Features:
• Intuitive controls with tap mechanics
• Increasing difficulty that rewards smart play
• Unique hidden and frozen piece mechanics
• Clean visuals and satisfying merge animations
• Endless puzzle fun for both casual and strategic players

Think ahead, keep your slots clear, and master the art of merging. Can you solve every puzzle and become the ultimate Domino Stack Sort strategist?
