About this game

Stack Mettle is a colorful strategy puzzle built around one simple idea: every move is legal, but the smartest moves matter.

Move the top block from one stack to another and organize each stack into a complete matching set. Unlike traditional sorting puzzles, Stack Mettle gives you freedom to place blocks wherever there is space. The challenge is not whether a move is allowed — it is whether the move brings you closer to an efficient solution.

Features:

• Free-move stack puzzle gameplay
• Increasingly challenging levels
• Efficiency-based scoring
• Replay levels to improve your best score
• Clear colors, symbols, and polished block visuals
• Smooth animations and responsive controls
• Satisfying flower and confetti celebrations
• Offline gameplay with no account required

Completing a level is only the beginning. Solve it with fewer moves, improve your score, and prove your Stack Mettle.
