**Shape Stackers** is a physics-based tower-building game where every piece matters. Stack colorful shapes into a growing tower, balance awkward blocks, and try to reach the goal line without sending everything tumbling. Play through 100 single-player levels with rising height goals, changing backgrounds, and unpredictable pieces. Some blocks are larger and harder to balance, some cursed blocks are tiny, and ghost blocks vanish when they touch another block, taking that block with them. Want a challenge with a friend? Switch to 2-player mode and take turns stacking pieces. The player who drops the block that knocks the tower over loses. Simple to learn, tricky to master, and full of wobbly “just one more block” moments.

- Realistic physics destruction

- Hundreds of challenging levels
