Stack Mettle Live

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.
