About this game

777 Stack is a quick-thinking number puzzle about building the perfect tower. Tiles with digits drop from above, and your task is to place them so that each stack adds up exactly to 7, 14 or 21. Every tile you catch changes the total, so you have to keep the current sum in mind while already planning where the next one will land.

Sometimes a single piece completes the target, other times you’ll need a careful sequence of numbers to reach the right total without overshooting it. A moment of distraction can ruin a promising structure, while a clever move can suddenly turn a messy pile into a neat, finished stack.

777 Stack blends simple rules with light mental arithmetic, creating short, focused sessions that train attention and quick calculation in a warm, glowing arcade atmosphere.
